Suggested Specifications

There are many factors that determine how many virtual servers you can run. Below you can find specifications for a Medium Production Cloud.

An OnApp installation requires at least four physical machines – three for the Control Panel server nodes, and the other for the compute resource server. You can have as many compute resource servers as you need. You will also need storage for your virtual servers (a data store), and we recommend that you set up a separate server for storing backups and templates.
