AI agent An AI-powered program that performs complex multitasking autonomously. Unlike a typical chatbot, which responds to individual requests, an agent sets a goal and plans the steps to achieve it. For example, an agent can collect brand mentions on the Internet, analyze them and prepare a report, freeing a person from routine searchingThe key "superpowers" of such an agent are memory, planning, and access to external data. It stores intermediate results (like a chatbot's "notebook and pen"), breaks the task down into steps, and, if necessary, calls external service APIs (web search, databases, computing tools). This allows the agent to independently adjust its plan on the fly if the initial information is insufficient, and it continually adjusts its actions.

Why deploy an agent on a VPS?

VPS server with the LLM interface is treated not just as a remote machine, but as a full-fledged platform for intelligent agentsFirst and foremost, this ensures round-the-clock availability: the AI agent can operate 24/7, not just when the user's computer is turned on. In practice, this allows for real-time monitoring and automation tasks—for example, monitoring prices on marketplaces or website changes, sending alerts when important events occur.

Furthermore, a private VPS provides greater control and data security. Many organizations prefer on-premises LLM solutions to avoid transferring sensitive data to the cloud. VPS can be used to deploy private LLM models, email processing (spam filtering, highlighting important emails), and log analytics—all on-premises. Finally, VPS is usually less expensive than dedicated cloud LLM services: you simply pay for the server and control the computing and traffic yourself.

AI Agent Capabilities on VPS

An AI agent running on a VPS can automate a huge number of routine tasks. For example, typical agent functions The server includes:

• Monitoring resources and websites24/7 checking for changes on the website or product prices, monitoring exchange rates, weather, news, stock quotes, etc.

• Process orchestration: running scripts and pipelines on a schedule (via cron, Airflow, etc.), managing backups, updates, and other system tasks.

• Data analysis: automatic log processing (grep, awk), text recognition (OCR) or audio (Whisper), generation of summaries and reports based on incoming data.

• AI DevOps: The agent can analyze metrics and logs, identify problems with servers or applications, make decisions (for example, restart the service), and send notifications to the administrator (via Telegram, email, Slack, etc.).

• Working with mail and messagesIf the VPS has a mail server or a Telegram/Discord bot connected, the agent can classify emails, filter spam, respond to requests, or forward messages, freeing the user from routine communication.

Applications can be found in virtually any field: from collecting research and calculating forecasts (the agent can run data analysis via Python and visualize the results) to supporting digital "colleagues" who assist in marketing, HR, sales, and more. The agent performs all these tasks autonomously, "retrieving" additional information from external systems as needed and generating a final conclusion or report.

Using the tool n8n You can visually construct the AI agent's workflow: the diagram launches an "AI Agent" node, which communicates with messengers, databases, and other services via an API.

Services and APIs for AI Agents

Implementing an AI agent typically involves combining cloud-based LLM models and integration with various services. For example, OpenAI provides an API for GPT models (GPT-4, GPT-3.5, etc.), as well as a set of built-in tools. OpenAI recently released Responses API – a new primitive for agents that combines regular chat with the ability to use tools (web search, file search, emulated desktop access, etc.). This allows a single command to trigger multiple operations at once: the agent can enter a search query, process the resulting text, and generate output, all within a single conversation. OpenAI also introduced the Agents SDK for simplified agent orchestration (works with their API and even with models from other providers).

Anthropic Claude (and the new tool Claude Code) is another example. Claude Code is a command-line interface for "agent programming" from Anthropic: you run Claude in the terminal, and the agent can now, for example, write and edit code, run calculations, and return results. Anthropic recently added a Python code execution tool to its API, allowing the Claude agent to execute scripts and build graphs without external tools. The same release also introduced the MCP connector, which allows Claude to access tools from other services (via the MCP protocol), including Zapier, Asana, and others. This means your agent can directly interact with hundreds of apps (Slack, Google Sheets, Trello, and others) through these integrations.

Managing the APIs themselves boils down to exchanging HTTP requests and JSON. Almost any system with a REST API can be an agent "instrument," from corporate CRMs to public weather services or exchange-traded funds. Popular no-code platforms (Zapier, Make/Integromat, Pipedream, n8n) already have ready-made connectors to OpenAI and Claude, simplifying the creation of action chains.

Tools and platforms for running agents

There are ready-made solutions and frameworks for deploying AI agents on a VPS. For example, n8n is an open platform for visually building automations. You can install it on your server and use drag-and-drop to connect nodes: webhooks, databases, HTTP requests, and blocks. OpenAI/Claude for communicating with LLM. Some hosting providers even offer VPS with a pre-configured n8n, allowing you to start building the agent right away without the hassle of configuration.

There are also specialized open-source frameworks: DocsGPT, agenticSeek, Depthnet, Airi and others. For example, DocsGPT combines LLM with document analysis, agenticSeek can select optimal agents and even generate voice responses, Depthnet is trained 24/7 for monitoring tasks, and Airi can play games, recognize speech, and chat via Discord/TG. These systems are experimental, but they demonstrate the broad application of agents—from technical tasks to creative ones (AI worker, analyst, tester, etc.).

Additionally, if privacy is important to you and you want to run models locally, you can install your own LLMs on a VPS. There are tools like llama.cpp, Ollam, LM Studio and others that allow you to run models like LLaMA, Mistral, Gemma, and others on CPU/VPS. This provides complete independence from the cloud: all data remains on your server, and the models run without connecting to external services. In this case, the agent is controlled either by your code (in Python, Node.js etc.), or the above-mentioned frameworks, but with a local backend.

What opportunities do AI agents ultimately provide?

Running an AI agent on a VPS opens up vast automation and monitoring capabilities. A server with a "brain" powered by LLM can handle tasks 24/7, from tracking information and generating reports to full-fledged DevOps support and client interactions. These agents can be built using cloud services from OpenAI and Anthropic, as well as local open-source models. Integrations are crucial: thanks to API nodes (HTTP, databases, and messengers), the agent gains full access to the digital world.

Popular tools like n8n allow you to quickly prototype such systems without deep programming, and advanced users can write their own agents through Claude Code or the OpenAI Agents SDK library. All of these allow you to integrate LLM with any external services. If you're riding the IT hype and want to explore this approach, start with simple scenarios (for example, price monitoring or converting emails into tasks) and gradually increase complexity: resource management on a VPS is a perfect fit for an AI agent. Ultimately, a VPS becomes not just a virtual machine, but a flexible platform for your autonomous digital assistant.

In the age of digitalization, a company's infrastructure, especially web projects and services, depends on the chosen server solution. The modern market offers a variety of options, among which virtual private servers (VPS) occupy a special place.VPS) and highlighted (dedicated) servers. Despite their superficial similarity—both provide dedicated resources for projects—these solutions differ significantly technically and organizationally. The choice between them is determined by management, performance, security, and budget requirements. This article provides a comparative analysis of a powerful VPS and a dedicated server costing approximately 3,400 hryvnias per month, as well as real-world use cases.

What are the differences between VPS and dedicated?

A VPS is a virtualized environment created on a physical server using virtualization technologies such as KVM, OpenVZ, and others. Multiple VPSs can coexist on a single physical server, each with guaranteed CPU, RAM, and storage. This type of server provides flexibility, rapid scalability, choice of operating system, and easy administration via SSH or control panels.

A dedicated server is a physical server completely dedicated to a single client. All computing resources (processors, memory, disks) are allocated to it with maximum isolation. This type of server is ideal for projects with high performance, security, and customization requirements, as the client has complete control over the hardware and can configure the system at the hardware level.

Comparison table of both solutions

Although virtualization has advanced significantly in recent years, the lines between VPS and dedicated servers are blurring. However, there are still nuances that are important when choosing between these two solutions, so let's discuss these nuances in more detail.

A real-world comparison of VPS and Dedicated using SIDATA plans as an example

For a real comparison, let's take the current tariffs from SIDATA costs 3400 hryvnia per month.

The raw data shows a 3:1 advantage for VPS over Dedicated. This makes sense, as VPS is cheaper than renting the entire system.

In real-world use, VPS can deliver high performance for tasks related to websites, applications, databases, and services with variable loads. Its rapid scalability makes it convenient for growing projects and changing requirements.

A dedicated server is more suitable for projects requiring maximum power and a stable workload without virtualization, for computing-related projects that require a large, immediate workload, and for those requiring specific hardware configurations or additional physical security.

For growing businesses, a VPS combines flexibility and performance, but for mission-critical systems without compromise, a dedicated server is a better choice.

A real-world comparison of VPS and Dedicated based on SIDATA plans and practical use cases

Next, we will consider not only the technical characteristics of VPS and dedicated server plans from SIDATA, but also real-life scenarios for their use in business through hosting on online accounting server.

When is VPS more profitable?

Accounting for small businesses

For a sole proprietorship with 2–5 users, the START or BASE+ VPS plans offer sufficient resources, including fast NVMe drives, backups, and out-of-the-box support for 1C and MEDoc. The savings are obvious: rent starts from ₴350–₴1,150 instead of ₴3,400 per month.

Test environments and pilot projects

A company is launching a new service or testing a new configuration in 1C:Enterprise. There's no point in immediately purchasing a dedicated server. A VPS on the BASE or BASE+X plans allows you to deploy the system in 15 minutes and test it in real-world conditions without additional costs.

Branches and remote employees

When an accountant or manager works from different locations in Ukraine or Europe, it's more convenient to host 1C in the cloud on a VPS. For example, the MEDIUM plan covers the needs of 5-7 users with sufficient performance and backup, so if your accounting department is scattered across the country, it's enough to cover all the needs of up to 7 users while saving you money.

When is Dedicated needed?

Large accounting system (20+ users)

For example, you have a manufacturing facility or branch network with a large 1C database. The workload is consistently high, and it's critical to isolate it in a single environment without resorting to virtualization. Firstly, a dedicated server offers more flexible management, and secondly, you'll get more RAM and a larger hard drive to store your substantial databases and sensitive company data.

Intensive integration with other services

When 1C is connected to CRM, online banking, warehouse systems, and external APIs, constant data exchange requires a dedicated server to avoid the risk of performance degradation due to "neighbors."

Long-term projects with increased safety requirements

Financial companies or corporations where complete control over the environment is essential—audits, certifications, compliance with internal policies. Dedicated ensures that resources are not shared with other tenants, minimizing the risk of data leakage.

The choice between a VPS and a dedicated server should be based on the specific needs and expectations for performance and security. A VPS is ideal when dynamism and flexibility are needed, while a dedicated server is ideal when maximum control and unparalleled reliability are critical, but require more management resources.

Thus, examining real-world cases helps us understand that VPS is more about flexibility, simplicity, and accelerated acceleration for dynamic projects, while a dedicated server is ideal for businesses requiring absolute control, high stability, and adaptation to unique hardware needs. The choice depends on the priorities and specific workload of your product.

What do we choose in the end?

There's a clear answer to this question: the choice depends on your priorities and specific business goals. Despite virtualization, VPS today can offer performance comparable to or even superior to a dedicated server in a number of respects, while remaining more flexible and easier to administer.

A dedicated server makes sense in scenarios where maximum isolation, full physical control, and predictable performance without the risk of interference from neighbors are important.

Based on SIDATA's 3,400 UAH plan, a VPS offers a more powerful processor and high-speed NVMe storage, which is beneficial for dynamic projects. A dedicated server may be preferable for memory-intensive workloads and when complete physical isolation is critical.

Automation of business processes is the basis for sustainable development of the company. For many years, the leader in this area in Ukraine was 1C, which provided accounting, management tasks and interaction with government regulations. However, after the introduction of sanctions against 1C, products under new names appeared on the market - BAF and BASThese systems have become a de facto replacement for the familiar platform and configurations.

BAF (Business Automation Framework) is a platform that replaced 1C. BAS (Business Automation Software) is a configuration, i.e. application solutions for accounting, personnel management, trade and production.

“Legally, these are new products, but technically, they are direct successors to 1C solutions.”

However, many companies are faced with the question: is it necessary to switch to BAS and when is it appropriate?

When should you think about switching?

The transition from 1C to BAS is not so much a matter of convenience as a strategic decision.

Firstly, new BAS products receive regular updates that take into account changes in legislation and new requirements for accounting and tax accounting. Old 1C configurations (for example, UTP or ZUP) are gradually no longer supported.

Secondly, BAS offers modern capabilities:

• access via browser;

• updated interface;

• accelerated work with reports and reference books;

• convenient mechanisms for integration with external services.

Thirdly, legal risks. Despite the fact that there is no direct ban on the use of old products, businesses under sanctions prefer to work with legal solutions.

“For companies that cooperate with European partners or use server rental, the issue of switching to BAS becomes especially relevant: the legality and transparency of decisions here come to the forefront.”

When should you postpone the transition?

However, not all businesses need to make the transition immediately. Here's why:

1. A large number of improvements. If the current 1C configuration is significantly modified, then transferring or rewriting the functionality for BAS will be expensive. In some cases, it is cheaper to support the old system.

2. Hardware resources. BAS is more demanding in terms of performance. If a company uses older equipment, it may require dedicated server rental or transfer the base to VPS/VDSOtherwise, the system will start to work noticeably slower.

3. Employee training. The new BAS interface requires time for adaptation. If work processes are highly dependent on the speed and experience of the staff, then the implementation should be planned gradually.

4. Legislative risks. Paradoxically, the transition to BAS does not guarantee absolute security. In the event of new sanctions, BAS solutions may also be subject to restrictions. In such a situation, alternative business systems will have to be considered: SAP, Microsoft Dynamics or localized Ukrainian products.

What technical nuances arise during the transition?

For those who are still considering the transition, it is important to know a number of technical points:

• 1C licenses are suitable for BAF. The old and new platforms can work in parallel.

• 1C configurations can be run on BAF without critical problems.

• Servers. In most cases, it is more convenient to deploy BAS not on local PCs, but on virtual servers (VPS or VDS). This approach allows for scalability, stability of operation and access from different points.

• If the company is focused on long-term work, it is more profitable to consider server rental in Europe - this reduces the risk of blocking and ensures higher data security.

“Using a virtual server is becoming a must for companies that plan to scale their accounting and provide access to employees from different cities and countries.”

In what cases is the transition really necessary?

There are situations when the transition to BAS becomes inevitable:

• lack of updates for the old configuration, which makes it impossible to maintain records in accordance with the law;

• critical need for new functions (for example, in production management, integration with banks, CRM or online services);

• business expansion, where old systems can no longer cope with the load.

Also, if you want, you can check out our material - How to properly migrate from an on-premises environment to the cloud?

In such cases, there are two approaches to consider:

1. Full transition to BAS with modifications, if they are critically important.

2. Parallel work: using the old configuration for familiar tasks and launching BAS for updated accounting, with partial data synchronization.

Conclusions

The transition from 1C to BAS is an ambiguous decision. It provides access to modern capabilities, updates and legal use of the product, but requires investment in training, server capacity and transfer of modifications.

For small businesses without complex modifications, the transition can be relatively painless. For larger companies with custom developments, this step will require a strategic approach and significant resources.

“The key benchmark for businesses is the balance between the costs of transition and the benefits of using a more modern and stable solution.”

Given the current reality, if your company already works with virtual servers (VPS/VDS), uses server rental or is considering server rental in Europe, then switching to BAS can be considered a logical step. If the old 1C fully copes with the tasks, and there are too many improvements, it is worth waiting and planning the migration at a more favorable moment.

Ukrainian businesses increasingly need to move to the cloud - especially when it comes to such an important aspect as accounting. Why? Local solutions are subject to serious risks: equipment failure, viruses, lack of backup and limited access to data, we are not even talking about war and arrivals at any moment - all this can result in serious losses for business, and managing these risks is becoming much more expensive than transferring the entire local IT infrastructure to the cloud, much cheaper.

That's why, virtual server (VPS) — is a reliable and flexible cloud solution that allows you to store and process accounting data in a secure location. Thanks to VPS, a business gets constant access to the accounting system from anywhere in the world, information protection, automatic backup and technical stability.

But the question arises, how to safely and correctly migrate to the cloud from a local environment, so as not to lose any data, configurations, without downtime, and simply not to lose important data.

How to properly prepare for migration?

Before migrating accounting and other business applications to the cloud, it is important to conduct thorough preparation. A competent approach at this stage helps to avoid downtime, data transfer errors, and failures in the operation of key systems.

Audit of current IT infrastructure

The first step is to determine what exactly we plan to transfer. Usually, we send accounting programs (1C or BAS), CRM, office applications, and electronic document exchange services (MEDoc) to the cloud.

By the way, you can find out how to switch from 1C to BAS Here.

Resource assessment and timing

It is important to ask the right questions in advance:

• How many users will work with the cloud solution?

• What volumes of data need to be transferred?

• What is the speed of your internet connection?

Migrating your entire database to the cloud can take a significant amount of time, especially on slow connections. To avoid disruptions, plan your migration for periods of low business activity, such as after-hours or weekends.

Preparation of programs and accesses

Before we begin migrations need to:

• Check availability licenses, installation files and current versions accounting programs.

• Do full data backup and check its integrity.

• Prepare everything digital signature keys, login data for banks, email, MEDoc and other important systems.

• Check availability backup copies of configurations.

Here is an example of a case of correct migration:

One of our clients decided to move her accounting in the cloudThe work process was built on the basis of 1C, MEDoc, CRM system.

First, we conducted an audit: we looked at what programs were used, how many employees worked with them, whether everything was updated and whether there were the necessary licenses and electronic signatures. Then we clarified the amount of information that needed to be transferred to the cloud and measured the speed of the Internet channel. It turned out that copying would take a lot of time - migration always occurs at night so as not to interfere with business during the main business hours.

Before the migration itself, we updated all the programs, made backup copies and checked that everything works correctly. On our side, we configured the virtual server in advance for the needs of the business: the required configuration, installed programs.

The move was arranged on a day off so as not to interrupt the work process. On Monday, all employees began working calmly in the new cloud environment - with the same functionality, but without dependence on one computer and with access from anywhere.

This approach has shown that migration can proceed smoothly and without losses, and most importantly, free of charge for the client, if everything is thought out in advance.

How did we choose a server to migrate to the cloud?

Once it becomes clear that the company is truly ready to move to the cloud, the next important step is to choose the right server configuration. Here you can’t just take “something in between” - everything depends on the number of employees, the types of programs and the amount of data they work with.

There were three users in this case: an accountant, a manager, and a customer service specialist. They all used 1C, MEDoc, worked with a bank and email. The tasks were typical for accounting - accounting, reporting, daily operational work. Based on this, we proposed BASE tariff - He fit the requirements perfectly.

The BASE tariff includes:
– 2 Intel processor cores
– 4 GB of RAM
– 60 GB on NVMe disk
– automatic backup for 7 days
– support of programs: MEDoc, Vchasno, bank-client, EDS

Such a server fully covers the needs of 2-3 users and ensures stable, fast operation of all necessary programs. In addition, the configuration allows for expansion: if necessary, the server can be scaled - add resources, connect more users.

Thus, the choice was made without overpaying, but with a margin of reliability and flexibility. This is important: not to take too much, but also not to limit yourself in the future.

How did we migrate data to the cloud?

Once the server has been selected and configured, it's time for the most important thing - transferring the entire accounting database and working environment. There is no need to rush here, so measure 7 times and then transfer.

First, we made a full backup copy of the local 1C database and other data. This is like insurance: even if something goes wrong, you can always roll back. We saved the copy on an external drive and in cloud storage to be on the safe side as much as possible.

Activated the virtual server, then took access to the archive with the database, installation files. On the virtual server installed 1C, MEDoc, configured access, users, checked the correctness of the keys.

When the server was fully ready, all three employees connected on Monday and tested the environment: generated a report, sent a document via MEDoc, made a payment via a bank. They checked everything, from access rights to the system response speed.

Possible mistakes and how to avoid them?

Moving your accounting to the cloud is a fairly resource-intensive process, and it’s easy to make mistakes that will later turn into unnecessary problems. We’ve collected the most common ones and will tell you how to avoid them.

One of the main mistakes is the lack of a database backup. Even if everything seems stable, you should always make a backup before any serious actions. Correctly written literally lost millions. This simple rule can save data in case of failures or unexpected errors.

The second mistake is choosing the wrong VPS configurationFor example, if there are three users, and the server is designed for one, there will be “smooth” operation, freezes and dissatisfaction of the entire team. It is better to immediately discuss the configuration with SIDATA technical support - they will suggest the best option for your needs.

Third, they forgot to transfer licenses, keys, certificates. Without them, neither 1C, nor MEDoc, nor the bank-client will work. To avoid rush and panic, it is better to make a list in advance: what needs to be transferred, checked, activated.

Also, people often forget to test the environment after setup.. Everything was transferred, everything started up — and off we went. And then it turns out that reports are not being generated or documents are not being sent. Therefore, a test drive is mandatory: log in under each user, perform typical operations, check electronic signatures and exchange with the bank.

Well, and perhaps the most unpleasant mistake is when they start working in parallel on the old one, and on the new system. This leads to data desynchronization, confusion in documents. Therefore, it is important: as soon as you are sure that everything works on the VPS, close the old system and work only in the cloud.

Migrating to the cloud is not scary

If you act step by step and carefully. The SIDATA team helps at every step: from server selection to full environment setup, and also performs migration in most cases for free! As a result, you get a modern, stable and secure environment for your accounting - without headaches and with support you can rely on.

Modern business processes are increasingly moving to the cloud. This is especially true for accounting, a critical area where sustainability, security, and access to data directly affect management decisions. In this article, we will look at why you should place accounting systems online, what VPS better than local hosting, what determines the cost of renting a virtual server, and what conclusions can be drawn before making a decision.

Why move accounting to an online environment?

In a rapidly digitalizing business environment, moving accounting online is not just a fashionable trend, but a logical step towards security, efficiency, and sustainability. “Today, data is the main asset. Its loss can result in a loss of not only finances for a company, but also its reputation.”

1 Data protection: comes first

The traditional model of storing accounting data - on a desktop PC or in a local network - has long ceased to be safe. Virus attacks, hardware failures, user errors or a simple disk failure can lead to the loss of all information.

Online accounting based on VPS or VDS dramatically reduces these risks.

A cloud server rented from a provider like SIDATA, is physically located in a data center with access control, backup power, and a failover protection system. The benefit is obvious: you get an environment where data is protected technically and legally, depending on the jurisdiction of the data center.

If an entrepreneur wants to ensure the safety of information about his company's activities, storing this data on a local computer is simply not safe.

2 Online access and flexibility

Another weighty argument is the availability of accounting data from anywhere in the world. An accountant, being in another country or working remotely, gets the opportunity to fully interact with the system: conduct transactions, generate reports, manage payments.

It is also convenient to organize joint work: you can assign access rights, differentiate roles and keep records in parallel for several employees.

3 Maintenance? It's already included

Online services based on virtual servers do not require any effort from the user to update or maintain the system. The provider takes care of all of this. You do not need to hire a separate administrator, solve backup, update, or security control tasks. This is especially important for small and medium businesses.

"If your accounting is maintained on a VPS virtual server, you pay for the service, not the equipment. This removes most of the organizational tasks."

4 Saving time and resources

A virtual server is an all-inclusive solution, especially when rented from a specialized company like SIDATA. You don’t need to buy a server, worry about its maintenance and upgrades. All that is required is a stable Internet connection and basic workflow setup.

Besides, the cost of renting a virtual server is significantly lower than the total cost of purchasing and maintaining your own equipmentFor entrepreneurs, this is an obvious savings.

Remote access to data, automated backup, reduced dependence on local infrastructure - all these are arguments in favor of virtualization. When placing an accounting system on a virtual server, you ensure:

• Continuous access to the system, regardless of your workplace or device.
• Minimizing the risks of data loss, thanks to backup and reserve systems.
• Compliance with regulatory safety, especially when hosting data in European or US data centers, as SIDATA does.

On-premise solution or VPS?

When it comes to accounting automation, a business owner sooner or later faces an important question: where is it better to place the accounting system - locally, on office equipment, or in a virtual environment, renting a VPS? Both approaches have their own characteristics, but in modern conditions the balance is increasingly tilted towards cloud solutions.

Cloud accounting isn't just convenient. It's a strategy that provides stability and control under any circumstances.

Why do many people abandon local servers?

Placing an accounting program on an office computer or on an internal server seems logical - especially to those who are used to keeping everything "at home". But in practice, such a solution turns into a whole series of risks and limitations.

First of all, it is necessary invest in equipment: buy a server, take care of uninterruptible power supply, organize backup, provide protection from overheating and dust. These aspects are usually not taken into account, but ignoring them means exposing the business to unjustified risk.

Secondly, access to the accounting system outside the office is difficultSetting up remote access requires a separate channel, a static IP, and certain technical skills. And even after setting up, the stability of the connection is far from guaranteed.

Even if there are no legal grounds for seizing equipment, no one is immune from unscheduled inspections or unauthorized actions that can temporarily paralyze a business.

What does VPS offer?

A virtual private server (VPS) provided by companies like SIDATA, eliminates most of these problems. Everything is hosted in a data center where:

• backup power supply systems are in operation;

• the temperature regime is observed;

• fire safety is in effect;

• there is protection against unauthorized access;

• high connection speed is ensured - up to 1000 Mbit.

And all this is included in fixed monthly cost - from 350 UAH. for VPS with basic configuration. You do not need to pay separately for electricity, internet, security or air conditioning.

Full control and access to the system - 24/7, from anywhere in the world. This is especially important if the accountant or business owner works remotely or is located abroad.

Are there any disadvantages to VPS?

Undoubtedly, cloud solution requires a stable internet connectionHowever, in modern realities this is no longer a problem - a reliable communication channel can be provided almost everywhere for reasonable money.

The monthly fee is another argument that may scare off those who expect to "save money." However, it is worth considering that a one-time investment in a local server and its maintenance ultimately costs more, especially when scaling a business.

Comparison of on-premise and cloud solutions

What does the price of server rental depend on?

Choosing a VPS is not only a matter of reliability and security, but also a matter of rational budget allocation. The cost of renting a virtual server is not fixed and depends on several key factors at once.

The price of VPS is not formed arbitrarily - it reflects the resources that you receive for specific tasks of your accounting department.

1 Number of users

The first thing that determines the cost is how many employees will work simultaneously with the accounting system. One accountant working with documents and the bank requires a minimum set of resources. But if there are already five users, the load increases, and the server must match.

SIDATA offers structured tariffs based on the number of active users. For example:

• START — from 350 UAH/month, For 1-2 users.

• base — from 900 UAH/month, For 2-3 users.

• MEDIUM — 1600 UAH/month, For 5-7 users.

• XXXL+ — 3950 UAH/month, For 20 or more users.

When scaling a company, it is important to update the tariff in a timely manner so that employees do not suffer from “slow” accounting.

2 VPS Characteristics

No less important role in pricing is played by server technical parameters:

• Amount of RAM — the higher, the more tasks the server can process simultaneously.

• Processor power (CPU) — affects the speed of processing operations in 1C, MEDoc and other systems.

• Disk size and type (NVME) — especially critical for working with large databases.

• Communication channel capacity - ensures fast operation without delays and freezes.

SIDATA offers servers with modern NVME disks, from 40GB to 2TB, And high connection speed (1000 Mbit), which significantly increases the productivity of online accounting.

3 Additional features

It is important to take into account that the price of all VPS from SIDATA already includes:

• Backup data (up to 7 days),

• Integration with MEDoc, Vchasno, EDS and banks,

• Server protection and stable operation 24/7.

That is, renting a VPS is not only about the hardware, but also about the service that allows the entrepreneur not to waste time on setup and maintenance.

Each SIDATA tariff is not just a lease. It is a comprehensive solution for business tasks, taking into account the number of employees, work intensity and security requirements.

Conclusions

Placing your accounting on a virtual server is not just a trend, but a strategically correct step. VPS and VDS servers from SIDATA allow you to reliably, conveniently and securely maintain financial records without the need to create and maintain physical infrastructure.

When comparing cloud VPS rental with all-inclusive SaaS solutions, it is important to understand that the latter are often more expensive and do not always allow for flexible management of confidential data. In addition, data in such services is stored in a closed environment, to which the business owner often does not have full access.

Using a VPS server is a balance between management, security and price. It is a choice in favor of control and independence.

SIDATA offers ready-made solutions for any business need. Regardless of the size of your company—whether it's a sole proprietorship or an international holding company—you can find the right VPS in just one day. This means accounting will work stably, quickly and safely.

Choosing the right provider to rent a virtual server for Node.js is a task that requires attention to detail. In this article, we will look at the key aspects to consider when choosing a VPS/VDS for your Node.js applications and present offers from SIDATA.

Choosing a provider for renting VPS for NodeJS

Why is VPS/VDS selection important for Node.js?

Node.js is a JavaScript runtime environment that enables you to build scalable web applications. To ensure stable operation of such applications, a reliable server with a suitable configuration is required. VPS (Virtual Private Server) and VDS (Virtual Dedicated Server) provide an isolated environment with dedicated resources, making them ideal for hosting Node.js applications.

Criteria for choosing a VPS/VDS provider

When choosing a provider, pay attention to the following aspects:

• Performance and reliability: Make sure your servers are equipped with modern processors and fast storage devices such as NVMe.
• Configuration flexibility: Ability to choose an operating system (Linux or Windows) and scale resources as needed.
• Support and Maintenance: 24/7 technical support and data backup.

Methods to Install Node.js on Linux

1. Installation via APT package manager (Ubuntu/Debian)

For basic needs, you can use standard repositories:

sudo apt update sudo apt install nodejs npm

However, the Node.js versions in the default repositories may be outdated. To get more current versions, it is recommended to use other methods.

2. Installation via NodeSource

NodeSource provides up-to-date versions of Node.js for various Linux distributions.

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash - sudo apt install -y nodejs

Replace 18.x to the version of Node.js you need.

3. Using Node Version Manager (NVM)

NVM allows you to install and manage multiple versions of Node.js on a single server.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash source ~/.bashrc nvm install --lts

After installation, you can switch between versions:

nvm use 16

This is especially useful if you work with multiple projects that require different versions of Node.js.

Checking the installation

After installation, make sure Node.js and npm are installed correctly:

node -v npm -v

You should see version numbers, confirming a successful installation.

Configuring and Managing Node.js Applications

To manage Node.js applications, it is recommended to use process managers such as PM2.

sudo npm install -g pm2 pm2 start app.js pm2 startup pm2 save

PM2 provides automatic restart of applications on crashes and allows you to easily manage multiple processes.

The method you choose to install Node.js depends on your specific needs and preferences. For most users, it is recommended to use NodeSource or NVM for up-to-date versions and management flexibility. Using a VPS provides the necessary environment for stable and efficient operation of Node.js applications.

“Proper server configuration is the key to reliable and productive operation of your applications.”

If you are looking for a reliable provider to rent a virtual server, pay attention to the offers of companies specializing in hosting for Node.js. They provide optimized solutions for developing and deploying your applications.

How to optimize NodeJs for correct operation of the server and your application?

Once you install Node.js on your VPS or VDS, it is important to not only launch the application, but also ensure its stable and efficient operation. Below are some Node.js optimization tips for virtual servers that will help improve the performance and reliability of your application.

1. Using Clustering for Multithreading

Node.js runs in single-threaded mode, which can limit resource usage on multi-processor systems. Module cluster allows you to run multiple processes, each of which will process part of the incoming requests, effectively distributing the load across all available processor cores.

2. Setting up a reverse proxy

It is recommended to use a reverse proxy such as Nginx or Apache in front of your Node.js application. This allows:

• Handle SSL encryption by offloading the main application.
• Cache static files, speeding up their delivery to the user.
• Distribute the load across multiple instances of an application.

Reverse proxy improves the performance and security of your application.

3. Implementation of compression and caching

To reduce the amount of data transferred and speed up page loading, we recommend:

• Use middleware compression in Express to enable Gzip compression.
• Implement caching using Redis or Memcached to store frequently accessed data.

These measures reduce the load on the server and improve application response.

4. Monitoring and managing processes

To ensure stable operation of the application, it is important:

• Use process managers such as PM2 to automatically restart your application on crashes:

npm install -g pm2 pm2 start app.js --name my-app

• Set up monitoring using tools like New Relic or Datadog to track performance and identify bottlenecks.

Effective monitoring helps to detect and resolve problems in a timely manner.

5. Optimize dependencies and code

Excessive or inefficient dependencies can slow down your application. It is recommended to:

• Conduct dependency audits periodically using npm audit or depcheck.
• Replace heavy libraries with lighter analogues, for example, use day.js instead of moment.js.
• Minimize the use of middleware in Express, leaving only the necessary ones.

Clean and optimized code leads to better performance.

6. Using CDN for static resources

To speed up the delivery of static files (images, styles, scripts), it is recommended to use content delivery networks (CDN), such as Cloudflare or AWS CloudFront. This allows you to:

• Reduce loading times by placing content closer to the user.
• Reduce the load on the main server.

CDN improves the availability and speed of your application.

7. Regularly update Node.js and dependencies

Updates to Node.js and the libraries it uses often include performance and security improvements. It is recommended to:

• Check for updates regularly using npm outdated.

• Update dependencies to the latest stable versions.

Up-to-date software ensures reliable and secure operation of the application.

By following these guidelines, you can set up and optimize your Node.js application to run efficiently on a virtual server, ensuring high performance and reliability.

The choice between a colocation service (placing your own equipment in a data center) and virtual server rental (in our case VPS/VDS) is an important stage in the development of any company's IT infrastructure. The level of control, costs, flexibility and compliance with regulatory requirements depend on this decision.

In this article, we will consider the main characteristics of both options, highlight the advantages and disadvantages, and provide a comparison table to make your choice easier.

What is colocation?

Colocation is a service of placing your own physical server in a professional data center. The client independently purchases the equipment, delivers it to the data center, where it is connected to the infrastructure: power supply, cooling system and communication channel.

All maintenance, component updates and administration remain on the customer's side. Responsibility for security and compliance also lies with the customer.

Advantages of colocation:

• Full control over equipment.
• Increased security (only authorized employees have physical access).
• Ability to strictly comply with regulatory requirements (e.g. GDPR, DPA).
• Independence from provider policies.
• Possibility of installing specific hardware.

Disadvantages of colocation:

• The need to purchase a server.
• The need to purchase and maintain equipment.
• Limited scalability - each upgrade requires physical intervention and “rack access”.
• Additional costs for logistics and maintenance.

What is virtual server rental (VPS / VDS)?

VPS (Virtual Private Server) is an isolated virtual environment on the provider's physical server. The user gets access to dedicated resources: CPU, RAM, disk, operating system. Configuration is carried out remotely through the control panel or SSH access.

Advantages of renting a VPS:

• There is no need to buy a server.
• Low cost compared to colocation.
• Quick start: the server is activated within a few minutes.
• High flexibility and scalability.
• There is no need to purchase and maintain physical equipment.
• Possibility to choose OS, configuration, tariff.

Disadvantages of renting a VPS:

• The level of security depends on the integrity of the provider.
• There is no possibility to install specific equipment or radically increase productivity.

Comparison table: colocation and VPS

Comparing Costs and Features: Colocation and Virtual Server Rental

When choosing an infrastructure for hosting servers, companies often face the need to choose between hosting their own equipment in a data center (colocation service) and renting a virtual server (VPS). Below we will consider two options using the example of the Ukrainian data center Volya and the virtual server provider SIDATA, and we will also conduct a comparative analysis of key parameters.

Server conditions in a rack (colocation) in the Volya data center

Additional services such as remote hands, upgrades, maintenance, component replacement, backup are usually paid for separately.

Also, don't forget about the cost of the server itself. Let's take an average server costing 45,000 ₴.

VPS rental conditions from SIDATA (Europe, Intel platform)

Additionally, the price includes:

• All plans include a free 5-day trial period.
• The price includes 24/7 support.
• Placement in European data centers of Tier III level and above.

Comparison table: Colocation from Volya vs VPS rental from SIDATA

Example: placement of 2U server (up to 350W)

As we can see, both colocation and renting a ready-made virtual server cost almost the same, yes, it is not a dedicated server, but considering the starting costs for a similar server plus or minus 45,000 ₴. It turns out to be more profitable to take a ready-made virtual server in the cloud than to pay for colocation and buy an expensive server and, in case of increased load, simply change the tariff to a higher one than to bother with buying, installing, servicing equipment in a rack.

Let's sum it up

Colocation is suitable for companies that already have equipment and a team ready to service the infrastructure. This approach may be justified if there are specific requirements for the hardware, a high degree of customization, or a policy of using only their own equipment.

Renting a virtual server from SIDATA offers a flexible, less expensive and faster solution. Within one tariff, the client receives a full set of services - from hardware resources to maintenance and data backup. Considering the level of cost and additional services, renting a VPS is a preferred solution for most typical tasks of small and medium businesses, especially in conditions of the need for remote access and high availability.

Both options have a right to exist and are used depending on the business objectives. Colocation is preferable for companies seeking maximum control, security and compliance. This solution is suitable for mature organizations with their own IT department and long-term planning.

Renting a VPS will be optimal for fast-growing projects that value flexibility, launch speed, and minimal initial costs. This is an approach with a minimal infrastructure load, allowing you to focus on business, not technical details.

If you decide to deploy Laravel on a virtual server (VPS/VDS) running Linux (in our case it was Ubuntu), but don't know where to start, then you've come to the right place. In this article, we'll look at installing Laravel on Ubuntu 20.04 — from preparing the environment to setting up the web server.

“Laravel is not just a framework, but an entire ecosystem for developing PHP applications. The simplicity of the syntax and powerful built-in tools make it the number one choice for many developers.”

Step 1: Preparing the VPS

Before installing Laravel, make sure your virtual server is updated. Run:

sudo apt update && sudo apt upgrade -y

You will also need to create a user with sudo access and configure UFW (firewall). If all this is already done, let's move on!

Step 2: Install Composer

Laravel requires Composer, a package manager for PHP. Let's install it:

sudo apt install curl php-cli php-mbstring unzip git curl -sS https://getcomposer.org/installer | php sudo mv composer.phar /usr/local/bin/composer

Let's check:

composer --version

If we see the version number, then everything is ok.

Step 3: Installing the LEMP stack

For Laravel to work, you need to deploy LEMP (Linux, Nginx, MySQL, PHP):

sudo apt install nginx mysql-server php-fpm php-mysql

Launch and add to startup:

sudo systemctl enable --now nginx mysql php7.4-fpm

Step 4: Install Laravel

Now download Laravel:

cd /var/www sudo git clone https://github.com/laravel/laravel.git

Go to the project folder:

cd /var/www/laravel sudo composer install

Step 5: Setting up access rights

sudo chown -R www-data:www-data /var/www/laravel sudo chmod -R 755 /var/www/laravel sudo chmod -R 777 /var/www/laravel/storage

Now Laravel has the required permissions.

Step 6: Setting up the environment

Create a configuration file:

cp .env.example .env

Generate an application key:

php artisan key:generate

“The .env file is the heart of Laravel’s configuration. It’s where you set up database settings, operating modes, and other critical settings.”

Edit .env:

nano .env

Update database parameters:

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=laravel DB_USERNAME=laravel DB_PASSWORD=your-password

Save the changes.

Step 7: Configure MySQL

Let's create a database and a user:

mysql -u root -p CREATE DATABASE laravel; CREATE USER 'laravel'@'localhost' IDENTIFIED BY 'your-password'; GRANT ALL PRIVILEGES ON laravel.* TO 'laravel'@'localhost'; FLUSH PRIVILEGES; EXIT;

Step 8: Configure Nginx

Editing the config:

sudo nano /etc/nginx/sites-available/laravel

Add:

server { listen 80; server_name your-domain.com; root /var/www/laravel/public; index index.php index.html index.htm; location / { try_files $uri $uri/ /index.php?$query_string; } location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/run/php/php7.4-fpm.sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~ /\.(ht|git|env|svn) { deny all; } }

Save, create a symbolic link and restart Nginx:

sudo ln -s /etc/nginx/sites-available/laravel /etc/nginx/sites-enabled/ sudo systemctl restart nginx

Step 9: Test and Launch

Let's run database migrations:

php artisan migrate

Open your browser and go to https://sidata.com.ua. If everything is done correctly, we will see the Laravel start page!

Now Laravel is successfully running on your virtual server. As you can see, there is nothing complicated, the main thing is to follow the instructions and check for errors if something went wrong.

“The best way to learn Laravel is to deploy it on a VPS and start developing your first project!”

WordPress has long ceased to be just a tool for blogging. Today it is a full-fledged ecosystem, on which both small sites and huge marketplaces operate. But any owner of a WP project sooner or later faces the question: which server to choose so that the site flies, and not crawls?

Virtual server (VPS) is the golden mean between traditional shared hosting and expensive dedicated-machines. It provides more power, flexibility and stability. But not every VPS can handle WordPress on 100%. Let's figure out what the ideal server for WP should have.

“WordPress loves speed. And speed means power, proper optimization, and the right choice of hosting.”

1. Performance

What to look for when choosing a VPS? Three key parameters are important:

• CPU. The more powerful the processor, the faster the server will process PHP requests.

• RAM. WordPress does not like a lack of RAM. The minimum is 2 GB, but for WooCommerce and busy sites, 4 GB is better.

• Disk. SSD or NVMe - this is not discussed. Hard disk drives (HDD) slow down the site.

Good virtual servers also support optimized stacks: Nginx + FastCGI, MariaDB instead of MySQL, PHP 8+.

2. Caching - the fewer requests, the faster the site

WordPress can be quite capricious. The more content, plugins and traffic, the greater the load on the server. Caching solves the problem. Let's look at the main levels:

“Caching is like anticipating user requests. The faster the server responds, the higher the visitor’s satisfaction.”

Opcode Cache

PHP code is executed line by line on the server. Each time it is compiled anew - this takes a long time. Opcode Cache allows storing the compiled code in RAM, reducing the load.

Object Cache

WordPress makes dozens of SQL queries every time a page is opened. Object Cache stores the results in memory (RAM), which speeds up access. Powered by Redis or Memcached.

Full Page Cache

If your site is a blog or an online store, the content does not change every second. It makes sense to simply save the HTML version of the page and give it to users, bypassing PHP and MySQL.

HTTP Accelerators

Instead of writing the cache to disk, you can store it in RAM. Varnish or FastCGI handle this with flying colors.

3. Server location: the closer, the faster

Clients from Europe? Renting servers in Germany or the Netherlands will give you minimal ping. Working for the American market? It is better to take a VPS in the USA.

In addition to physical location, CDN support is important. Cloudflare, BunnyCDN or similar networks will deliver content closer to the user.

4. Security: SSL, firewall and backups

WordPress is a tasty morsel for hackers. A good VPS should support:

• Automatic SSL Certificates

• Firewalls (UFW, CSF)

• DDoS protection

• Regular backups

Additionally, you can install Fail2Ban to protect against brute force attacks and hide the standard paths of the administration panel.

5. Why VPS and not shared hosting?

Shared hosting is like living in a dorm: shared resources, constant problems with neighbors, lack of productivity. VPS is your own apartment. You choose the configuration, install software, manage resources yourself. Plus, if the project grows, you can easily scale up.

“Shared hosting is a compromise. VPS is freedom.”

VPS according to needs

The best VPS for WordPress is a server that suits your project’s needs. A small site will be fine with 2GB of RAM and an SSD, but a large store will need at least 4–8GB of RAM, a powerful processor, and advanced caching settings.

If you need a VPS for eCommerce, here it is article to help you.

Look at reliability, support, geolocation, and additional features. And remember: site speed is not just convenience, but a ranking factor in Google. Fast site = more customers.
