What is the Best Practice about redis and managed wp service

[ Moderator note: moved to Fixing WordPress. ]

Hi guys,

I want to serve a service like managed wp services.

The server may have N pieces WordPress site and all of them have use Redis know but I don’t like the current situation because every customer can see other customer’s website Redis keys.

I want to isolate all customer’s redis from each other but redis instance for all customer sounds like a huge weight for the server.

So I need hear some experiences of yours.
What do you do about this situation on your project?

I’m open for all ideas I’m searching a secure and fast solution.

best regards.
