System requirements

The following hardware and software requirements must be met, to install and operate a Relution server.

Minimum hardware requirements

The following hardware is required to run a Relution server required:

  • 2 CPU cores
  • 4 GiB RAM
  • 1 network card
  • 10 GiB HDD/SSD
  • Additional storage space for user data, operating system and other applications and programs

External resource storage

We recommend using an external resource storage in generel, especially in these cases:

  • Installation and management of native apps on Windows devices
  • If native apps larger than 50 MB or in general a lot of native apps are used
  • Servers with more than 5000 devices

Relution supports configuring a separate S3 compatible storage system like Minio. You can find more information at Minio Installation

Internal network

The Relution service uses these ports to communicate with external services (database, directory service, mail server). The exact configuration depends on which services are used and whether the services run on separate servers (recommended).

If the servers servers are on the same network, no additional firewall configuration should be required. All ports are TCP.
