Seeking CentOS 7 Optimizations

Im thinking of switching to OVH as my new host but according to the information from them they only deal with hardware and i have to handle anything software related etc.

I want to know if theres any experienced people with root access centos 7 specific that can give me a list of recommendations i can do to ensure the most optimal experience when i get a server from them and install multicraft following this link: https://javapipe.com/blog/multicraft-control-panel/

When i get the “GAME-64-OC” for example i want to ensure the above link doesint skip anything important or if people can recommend optimization i can do before or after the above links instructions to ensure my experience with root access is a decent one since iv never had to deal with root access dedicated servers before!

Even a checklist i should do in centos cmd screen to ensure everything is secure and up to date.

Thanks in advance!
