Windows VPS for 1C

A rented server for 1C saves you from the office PC under a desk that nobody updates or backs up. But 1C on a VPS has its own quirks: the software licence is tied to the parameters of the virtual machine, users need both 1C and Windows licences, and core speed matters more than core count. Here is how to put together a 1C server for a small company.

This article is for a company where 1–10 people work in 1C:Accounting, Trade Management or Salary and HR Management and want to move the database from an office computer to a server in a data centre. How the Windows Server licence itself works and how to lock down RDP sign-in is covered in detail in Windows VPS: licensing, RDP and secure sign-in. Here we cover what 1C adds on top.

Three ways to run it

File database and remote desktop. The database sits on the server, the 1C platform is installed there too, and users connect to the server over RDP and work in their own sessions. This is the simplest option: you need nothing besides Windows and 1C. It suits 1–5 users. As the number of people and the size of the database grow, file mode starts to slow down under simultaneous writes, and if the database file is damaged in a crash, everyone is affected at once.

Client-server option. The VPS runs the 1C:Enterprise server and a database server — Microsoft SQL Server or PostgreSQL. Users connect with the thin client or over RDP. This setup handles more users and larger databases, but it needs a 1C server licence, more memory and an administrator who knows how to configure it. Companies usually switch to it when there are more than five people or the database has grown past a few gigabytes.

Publishing on a web server. The database is published through IIS or Apache, and users work in a browser or the thin client over HTTPS, without remote desktop. Then you need no licences for RDP sessions, but not every external data processor or piece of hardware works through the web client. This setup is often combined with RDP for the accountant who needs full access.

1C licences on a virtual server

Client licences are always required: one per simultaneous connection. In file mode over RDP all users work on one server, and the licences are activated on it.
A 1C server licence is needed only for the client-server option. For small companies there is the "Server MINI" edition for 5 connections; it still requires client licences.
A software licence is tied to the machine's parameters: network name, amount of memory, processor and motherboard model, network card. For a virtual server these are the parameters the virtual machine reports. If the host moves the server to a node with a different processor or you reduce memory when changing plans, the licence may stop working.
Reactivation is done with a spare PIN code: a licence comes with one main and two spare PIN codes. When the spare ones run out, the 1C company issues new PIN codes on request. Adding memory or disk usually does not reset the licence; reducing them does.

A hardware USB key cannot be attached to a virtual server directly, so software licences are used on a VPS. Before renting, ask the host whether the virtual machine's parameters change when it is moved between nodes and when you change plans. If the host promises to keep the processor model and MAC address, licences last for years.

Windows licences for 1C users

Without additional licences, Windows Server allows two people to connect over RDP at the same time, and those connections are intended for administration. If three or more accountants work in 1C through remote desktop, you need the Remote Desktop Session Host role and a licence for each user. From a host this is a monthly RDS SAL, and for a small team it can cost about as much as the server itself. Check its price before ordering.

Another route is a 1C server on Linux. The platform supports the 1C:Enterprise server on Linux with PostgreSQL; then no Windows Server licence is needed, and users work through the thin client. This saves money but requires an administrator familiar with Linux and PostgreSQL.

How much memory and how many cores

According to Microsoft's requirements, Windows Server 2022 itself starts with 2 GB of memory, and for Windows Server 2025 with the desktop experience Microsoft recommends 4 GB. On top of that, each 1C session over RDP takes 300–500 MB on average, and in the client-server option the 1C server and the database server use memory to cache the database. Guidelines for typical configurations:

Users	Setup	Cores	Memory	Disk
1–2	File database, RDP	2	4 GB	60 GB NVMe or more
3–5	File database, RDP	4	8 GB	80 GB NVMe or more
5–10	1C server and database server, RDP or thin client	4–8	16 GB	120 GB NVMe or more

These are starting points, not a rule: heavy configurations such as Integrated Automation and data exchange with a website need more. After a month of use, check the load in Task Manager and, if resources are short, move to a bigger plan, keeping the software licence in mind.

For 1C, core frequency matters more than the number of cores: posting documents and month-end closing run mostly in a single thread. Look for plans with processors from 3 GHz; the selection is VPS with high CPU frequency. Take NVMe disks only: a file database constantly reads and writes in small chunks; more in NVMe or SSD.

What a 1C server costs

According to the accsly catalog as of 1 November 2026, plans in Russian data centres that can run Windows cost the following (the catalog stores prices in roubles; dollar figures are rounded):

4 GB of memory: about $16 a month at the middle of the market, a quarter of the plans cheaper than about $12;
8 GB: median about $30, a quarter cheaper than about $21;
16 GB: median about $66.

Note that some plans include the Windows licence in the price and others add it as an option, which raises the total. RDS licences for users and 1C licences are paid separately. Windows plans in Russia from hosts that invoice legal entities are collected in VPS for 1C; all Windows plans are in VPS with Windows and RDP server.

For 1C the server location is almost always Russia: under Russian law, personal data of employees and counterparties must be stored in databases inside the country, exchanges with banks and electronic document flow work faster, and the company receives the accounting documents it needs from the host. More in How to choose a country for your server.

Database backups

Copies the host makes as disk snapshots protect against a server failure, but not against an accountant who deleted documents a week ago. 1C needs its own backups:

file database — an export to a .dt file from the Designer or a copy of the 1Cv8.1CD file while nobody is working in the database, for example on a nightly schedule;
client-server database — a regular dump with the database server's own tools: SQL Server backup or pg_dump for PostgreSQL.

Store the copies off the server and at least once a quarter check that the database can be restored from them. How to set up such copying is described in VPS backups.

Checklist before ordering

The setup is chosen: file database over RDP, client-server option or publishing on a web server.
1C client licences are counted and, if needed, a server licence.
The price of Windows in the plan is known, and of RDS SALs if there are more than two users.
The host has confirmed that the virtual machine's parameters do not change when it is moved between nodes.
Processor from 3 GHz, NVMe disk, memory with headroom according to the table above.
The server is in Russia, and the host issues invoices and accounting documents to the company.
RDP sign-in is open only to office and staff addresses, and database backups off the server are set up.

FAQ

Can I run 1C on a VPS?

Yes. Most often the database is placed on a Windows server and users work in it through remote desktop. For 5–10 users and large databases, a 1C server with SQL Server or PostgreSQL is installed, or the database is published on a web server.

How much memory does a VPS for 1C need?

For 1–2 users of a file database over RDP, about 4 GB; for 3–5 users, 8 GB; for the client-server option with 5–10 users, 16 GB or more. Core frequency matters more than core count: from 3 GHz.

Will my 1C licence stop working on a VPS?

A software licence is tied to the parameters of the virtual machine. It may need reactivation if you reduce memory or if the host moves the server to a node with a different processor. For this the licence comes with two spare PIN codes.

Do I need a 1C server licence?

Only for the client-server option. With a file database that users work in over RDP, client licences are enough. For small companies there is "Server MINI" for 5 connections.

How many accountants can work on a Windows VPS at the same time?

Without additional licences, Windows Server accepts two RDP connections for administration. If three or more people work on it, you need an RDS licence for each user; from a host these are paid monthly.

How much does a VPS for 1C cost?

According to the accsly catalog as of 1 November 2026, a plan with 4 GB of memory in a Russian data centre that can run Windows costs about $16 a month at the middle of the market, and one with 8 GB about $30 (rounded from roubles). Windows, RDS and 1C licences may be paid separately.

Docker on a VPS: getting startedDocker lets you run a bot, a website, a database and monitoring on one server without them getting in each other's way, and moving to another VPS comes down to copying a couple of files and the data. Installation takes five minutes; the real trouble starts later: database ports exposed to the internet, logs growing to tens of gigabytes and data that vanished along with a container. Here is how to avoid all of that from the start.
How to move a website from shared hosting to a VPSThe move itself takes a couple of hours; the mistakes usually happen around it: a forgotten cron job, .htaccess rules that nginx does not read, an AAAA record with the old address, or mail that disappeared along with the IP change. Below is the order of steps with commands and checks for a PHP and MySQL site.
Server control panels: ISPmanager, FASTPANEL, aaPanelA panel turns a VPS into the kind of dashboard you know from shared hosting: sites, databases, mail and certificates are set up with a few clicks instead of editing config files. The three panels most often installed on Russian and budget international servers are ISPmanager, FASTPANEL and aaPanel. They differ in price, memory requirements and how much of the server they take over.
Windows VPS: licensing, RDP and secure sign-inA Windows server costs more than Linux not only because of memory: the price includes a licence, and how it is arranged decides whether you are compliant and how many people can connect. An exposed RDP port is also the most common way such servers get hacked. Here are both topics.
When to move from shared hosting to a VPSA VPS does not make a site faster by itself: it gives you resources and freedom, and with them the job of running a server. Here is how to tell that hosting has become too small, when the problem can be solved without moving, and how to migrate a site so visitors notice nothing.
VPS backups: strategies and toolsOn a VPS, backups are your job, even if the plan says "backups included". We go through what exactly to back up, why a host snapshot is not enough, how to set up restic or BorgBackup in half an hour, and how to make sure you can actually restore from a backup.
First 10 steps after buying a VPS: securityBots start guessing passwords on a new server within minutes of it getting a public IP. Below are ten steps that close the most common holes in about an hour: commands for Ubuntu and Debian, the differences for AlmaLinux and Rocky Linux, and the checks that keep you from locking yourself out of your own server.
How to choose a country for your serverPut the server where your visitors are. For an audience across Europe, Germany, the Netherlands and Finland are convenient; for North America, the US East Coast. If you serve EU users, keeping the data in the EU makes GDPR simpler. Price hardly decides it: at the same host a server in Frankfurt, Amsterdam or New York usually costs the same, and only Asia and Australia are noticeably more expensive.
Hourly billing: when it pays offHourly billing pays off if you need the server for less than three weeks a month: for a test, a build, a one-off heavy job. At most hosts an hour costs exactly the monthly price divided by 730 hours, so over a full month you hardly overpay. The overpayment hides elsewhere: hourly plans are dearer on average, and for a server that runs all year, monthly billing or a year paid in advance usually comes out cheaper.
How much RAM and how many cores a website needsMost websites are fine with 2 GB of memory and one or two cores; a shop with thousands of products needs 4 GB and two cores. Memory matters more than cores: when it runs out, the site slows down or crashes, while an extra core without memory adds almost nothing. Below I show how to work out the memory for your site and how to see what it actually uses.
KVM or OpenVZ: which to chooseIn 2026 KVM is almost always the right pick: it costs a dollar or two more per month than OpenVZ, but everything runs on it, from Docker to Windows. OpenVZ makes sense in one narrow case, explained below, and at the end you will find the commands to check your own server in a minute.
NVMe or SSD: does it matter for a websiteFor a small site the difference between NVMe and SSD is barely noticeable, because pages are served from memory rather than from disk. It shows up in shops and sites with a large database. At the same host NVMe costs only about $0.50–1 a month more, and sometimes less, so what usually decides it is not the disk type but its size and how the host has limited it.
What is a VPS, in plain EnglishA VPS is a slice of a powerful physical server that you rent and that behaves like a separate computer, with its own operating system, its own IP address and full control. Below is how it differs from shared hosting, who needs one, what it costs and what to check right after you buy it.
VPS for a Telegram bot: what the bot needs and how to pick a planA bot with a menu and a few commands runs fine on the cheapest server, while a bot with broadcasts, files and a database hits completely different limits. Here is what a bot really consumes, which Telegram limits shape the choice of server and how to avoid overpaying.
How to test VPS ping and speed before you payThe numbers in a plan do not tell you the latency to your users or how fast the disk really is. Most of this can be measured before you pay, the rest in the first hour after launch. Here are the tools and how to read the results.
Corporate network on a VPS: remote access to the officeA rented server can become the hub of a company's private network: remote employees and branch offices connect through it to the ERP, file server, CRM and Git. Here are the common layouts, protocols, server requirements and security basics.
