Bitrix24 is developed in the PHP programming language, uses the MySQL database, Apache and nginx web servers, as well as a number of additional software.

It can be installed on a dedicated server in your corporate network or at a hosting provider, as well as on a VPS/VDS (virtual dedicated server).

Required server parameters

• at least 4 CPU cores

• at least 8 GB RAM

• at least 60 GB SSD NVME disk

• CentOS Stream 9 operating system

• "white" IP address

• open network ports: 22 (or another for SSH), 80, 443, 8893, 8894

Recommended tovendor configurations

Approximate server configurations with comfortable performance:

• Up to 50 users: Intel Xeon E3-1230v5 3.4 GHz, 4 cores / 2 x 2 TB HDD for portal files / 2 x 256 GB SSD for database files / 16 GB DDR4.

• 50 – 100 users: Intel Xeon E3-1230v5 3.4 GHz, 4 cores / 2 x 2 TB HDD for portal files / 2 x 256 GB SSD for database files / 24 GB DDR4.

• 100 – 500 users: Intel Xeon E3-1230v5 3.4 GHz, 4 cores / 2 x 2 TB HDD for portal files / 2 x 256 GB SSD for database files / 32 GB DDR4.

• 500 – 1000 users: Intel Xeon E5-1650v4 3.6 GHz, 6 cores / 2 x 4 TB HDD for portal files / 2 x 480 GB SSD for database files / 64 GB DDR4.

• 1000 – 5000 users: Intel Xeon E5-1650v4 3.6 GHz, 6 cores / 2 x 4 TB HDD for portal files / 2 x 480 GB SSD for database files / 128 GB DDR4.

• From 5000 users: 2 Intel Xeon E5-1650v4 servers 3.6 GHz, 6 cores / 2 x 4 TB HDD for portal files / 2 x 480 GB SSD for database files / 128 GB DDR4.

These configurations are approximate, and most projects may require significantly fewer resources. And for some, on the contrary, it may not be enough.

Additional information on storage

If you are deploying a boxed Bitrix24 to migrate from the cloud, you need to look at the space occupied in the cloud in the My tariff section and multiply by 3. This is how much space you need to provide on the server.

For large volumes of stored files in Bitrix24, the following scheme is often used:

• fast disk (SSD) - for OS, portal files and database (from 60 GB)

• cheap disk (HDD) or external object storage (S3) - for file storage and Bitrix backups

If you are deploying your own server, don't forget about reliable disk redundancy (RAID).

Examples of VPS hosting for Bitrix24 for 50 users

What you need to deploy Bitrix24

• root access from the server via ssh (or access from the hoster's office, where you can create a server, or from the hypervisor)

• a separate mailbox (e-mail, login, password and SMTP server address) from which the portal will send notifications and service letters

• a domain or subdomain linked to the server's IP address
