CNM Cloud Next

The CNM Next Server (previously known as CNM Lab Server; hereinafter, the Server) is a compute server that is used for learning and testing. While being a part of CNM Servers, the Server utilizes one DigitalOcean droplet, which is located at the 134.209.40.232 IP address, and shall support all the applications installed at the Fellow Server and, in addition, one Humhub and one Tiki Wiki CMS Groupware instances.

Platform

The Server is set up as a Digitalocean droplet with dedicated 1 vCPU and 2GB / 50GB Disk in its NYC3 datacenter (New York). The dedicated resources can be increased when the existing ones can no longer support all the services that the Server is expected to provide.

OS

Ubuntu 18.04.2 x64
