It’s a cache cluster. If you have an expensive query on your database or an api response that’s expensive to generate, you cache it in memory and then for some period of time whenever someone needs it, you return the cached version instead of doing the expensive work. Redis can do a whole lot more than that- data types, documents, etc etc but it’s a web scale caching layer.
…What? This is Redis. Linux doesn’t really benefit from this (aside from being an OS that can host Redis)
Wait I thought it’s an industry standard component used in the Linux space like systemd or something.

It was a very popular nosql key-value store. Used massively for caching, certainly web apps in general.
It was relicensed a few years ago to no longer be FOSS.
Pretty sure the FOSS fork that is now widely used is Valley.
That might be rsync XD
