Redis®* refers to an open-source (BSD licensed), in-memory data structure that is used as a database, message broker, and cache. Also, it supports data structures including strings, lists, hashes, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams.

Niles Partners is launching a product that will configure and publish Redis®* which is embedded pre-configured tool with Ubuntu and ready-to-launch AMI on Amazon EC2 which contains LAMP.

One of the best aspects of Redis®* is that it has built-in replication, Lua scripting, transactions, LRU eviction, and multiple levels of on-disk persistence, and provides high availability via Redis®* Sentinel and automatic partitioning with Redis®* Cluster. Redis®* works with an in-memory dataset that depends on your use case, you can persist it either by often dumping the dataset to disk or by affixing each command to a log. Also, the persistence can be disabled that is totally optional if you require a feature-rich in-memory cache.

Also, Redis®* supports trivial-to-setup master-slave asynchronous replication, along with quick non-blocking first synchronization, auto-reconnection with partial resynchronization on netsplit. Some other features of Redis®* include the following:

• Pub/Sub
• Lua scripting
• Keys with a limited time-to-live
• Transactions
• Automatic Failover
• LRU eviction of keys
