Use Cases

to cluster highly changing data with event notifications, e.g., user based events, and to queue and distribute background tasks

as a simple Memcache with Near Cache

as a cloud-wide scheduler of certain processes that need to be performed on some members

to share information (user information, queues, maps, etc.) on the fly with multiple members in different installations under OSGI environments

to share keys in a cluster where there is a web service interface on an application server and some validation

as a distributed topic (publish/subscribe server) to build scalable chat servers for smartphones

as a strongly consistent layer for its concurrency API which is Hazelcast’s CP (CP with respect the CAP principle) subsystem built on top of the Raft consensus algorithm

as a front layer for a Cassandra back-end

to distribute user object states across the cluster, to pass messages between objects and to share system data structures (static initialization state, mirrored objects, object identity generators)

as a multi-tenancy cache where each tenant has its own map

to share datasets, e.g., table-like data structure, to be used by applications

to distribute the load and collect status from Amazon EC2 servers where the front-end is developed using, for example, Spring framework

as a real-time streamer for performance detection

as storage for session data in web applications (enables horizontal scalability of the web application).
