Is Redis just a cache?

Question

I have been reading some Redis docs and trying the tutorial at http://try.redis-db.com/. So far, I can\'t see any difference between Redis and caching technologies like Velo

Answer 1

Actually there is no dependency between relative data representation (or any type of data representation) and database role (cache, permanent persistence etc).

Redis is good for cache it's true, but it's much more then just a cache. It's high speed fully in-memory database. It does persist data on disk. It's not relational, it's key-value storage.

We use it in production. Redis helps us to build software that handles thousands of requests per second and keep customer business data during whole natural lifecycle.
