RabbitMQ vs. Hazelcast

RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.

With its various distributed data structures, distributed caching capabilities, elastic nature, memcache support, integration with Spring and Hibernate and more importantly with so many happy users, Hazelcast is feature-rich, enterprise-ready and developer-friendly in-memory data grid solution.
