Hazelcast is an in-memory data grid that allows applications to share data across multiple nodes or instances in a highly distributed environment. Hazelcast provides:

• Distributed caching: For scalable, fault-tolerant cache management.
• Data partitioning: Efficiently spreads data across multiple nodes.
• Fault tolerance: Supports automatic failover and replication to avoid data loss.
• Persistence: Enables backing up cache data to persistent storage.
• Elastic scalability: Automatically scales up or down to handle changing loads.

Hazelcast can be run in two modes:

• Embedded mode: Hazelcast runs within the same JVM as your application.
• Client-server mode: Hazelcast runs as a separate service, and applications connect to it via the Hazelcast client.

In this guide, we’ll focus on using Hazelcast in embedded mode with Spring Boot.
