What is Azure Cache for Redis?

Azure Cache for Redis is a high-performance, in-memory caching solution that is implemented as a service in an Azure data center by Azure Cache for Redis. It generally runs on one or more machines and enables scalable and secure architectures. It offers a caching service that may be used from any Azure application, regardless of whether the application is built as a cloud service, a website, or inside of an Azure virtual machine. One of the main benefits of this architecture is speed, so in order to ensure fast access, it actually keeps as much data as it can in memory. Moreover, client applications that have the required access key are able to share caches.
