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

Not just a cache.

• In memory key-value storage
• Support multiple datatypes (strings, hashes, lists, sets, sorted sets, bitmaps, and hyperloglogs)
• It provides an ability to store cache data into physical storage (if needed).
• Support pub-sub model
• Redis cache provides replication for high availability (master/slave)
