Part of the Database glossary:

Redis is an open source key-value database sponsored by VMware.

Data in a key-value database has two parts: the key and the value. Because Redis can accept keys in a wide range of formats, operations can be executed on the server and reduce the client's workload. Redis is often used for caches to speed up web applications.

Redis is written in ANSI C and runs on POSIX systems such as Linux, Mac OS X and Solaris. It can be accessed by applications through its client API library.
