Azure Redis Cache is an in-memory data storage, or cache system, based on Redis that boosts the flexibility and efficiency of applications that rely significantly on backend data stores. It can handle massive numbers of application requests by storing highly trafficked data in server memory, where it can be written to and read fast. Redis open-source (OSS Redis) and Redis Enterprise (from Redis Labs) are both available as managed services through Azure Redis Cache. It offers safe and dedicated Redis server facilities and complete Redis API support. Microsoft runs this service, which can be helpful for any Azure-based or non-Azure-based application.
