Hazelcast provides real-time, scalable messaging for your large-scale applications
The Hazelcast Approach to Messaging
Messaging in a Microservices Environment
The Hazelcast Advantage
High Speed, In-Memory Pub/Sub Messaging
Developers find it easy to leverage Hazelcast to build out messaging pipelines, even at scale with low latency. Applications can subscribe to multiple topics, and multiple applications may publish to the same topic. Hazelcast orders messages, so subscribers process messages in the order they are actually published.
If you are familiar with JMS topics, it will be extremely simple to come up to speed with Hazelcast for real-time scalable messaging.
