Redis is an open-source in-memory database project released in May 2009 implementing a distributed, in-memory key-value store with optional durability. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, hyperloglogs, bitmaps and spatial indexes.

Redis is mostly single threaded, or double-threaded when it rewrites the AOF log.[1]

Redis is also provided as a service in different Cloud providers such as ElastiCache from Amazon Web Services, Azure Cache from Microsoft Azure, Alibaba Cloud offers ApsaraDB and Google Cloud Memorystore.
