Question is in the thread title. Thank you!
gavin Only for CP?
@gavin You can go with a 4 core machine. Should suffice. RAM can be 8 or 16GB.
prasad0889 I think so as a friend. CP is efficient. Doesn't use a lot of resources.
8GB RAM should be plenty for the control panel server at almost any cluster size. We are offloading responsibility from orchd (the control panel service) to appcd which runs per server to even further reduce the system requirements of the panel itself.
