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

Redis has unique abilities like ultra-fast lua-scripts. Its execution time equals to C commands execution. This also brings atomicity for sophisticated Redis data manipulation required for work many advanced objects like Locks and Semaphores.

There is a Redis based in memory data grid called Redisson which allows to easily build distributed application on Java. Thanks to distributed Lock, Semaphore, ReadWriteLock, CountDownLatch, ConcurrentMap objects and many others.

Perfectly works in cloud and supports AWS Elasticache, AWS Elasticache Cluster and Azure Redis Cache support
