Do you wish to install Memcached process?

Memcached is an additional application that helps to run web applications faster by caching objects and other things into RAM to make access to them very fast. It can cache a lot of different things used in web applications, variables, objects, database calls, API calls and web page renderings.

The name basically already says what it does mem = memory, cached well, its cached... both means memory cached. Basically you use as much free RAM as possible to speed up your web applications like websites and other stuff.

Do you wish to install Redis process?

Redis is a kind of in memory database system that belongs to the no SQL database family because it doesn't use SQL queries to store and access data.

Whether you need this depends on your web application. If you never heard of it and never used it before - you simply don't need it.

Do you wish to set up Watchdog (beta)?

Well, that is a bit hard to answer for a person who never used Cyberpanel.

However Watchdogs are nothing new. It's a monitoring process for the actual process. It checks if the process is still alive and working as intended. If it detects that something is not working it will attempt to get the main process up and running.

Linux and other OSs have watchdogs for all kind of processes and services. Mostly without you noticing anything. They're working in the background and making sure things are running.

Most likely this feature is for the Cyberpanel services and processes. As it says it is in beta it might be not a good idea to use it in production unless you want to really try it out and maybe even help the developers by reporting issues with it to them and etc.
