Minimum RAM requirements for the UCS installation

For the installation of Univention Corporate Server at least 1,4 GB RAM is required.
We recommend a minimum of 2GB RAM, therefore the installation process warns if less than that is detected.

Depending on the selected Software components more RAM might be required.
Additional software components may be installed later after the installation of UCS via the App-Center.

The installation might fail or get stuck in case not enough memory is available. Either the amount of available RAM memory or SWAP space should be increased before starting the installation.

If UCS is installed in cloud hosting solutions like the Amazon EC2 cloud (AWS), it may be necessary to adjust the instance type to a size of at least “t2.small” or larger. For the detailed instance size information see https://aws.amazon.com/ec2/instance-types/.
