Question

I am new to hazelcast and want to use the replicated map to share data between two microservices. Using spring-boot-starter cache with following two modules. Is it open source/free ?

  `enter code here`<!-- Core hazelcast module -->
    <dependency>
        <groupId>com.hazelcast</groupId>
        <artifactId>hazelcast</artifactId>
    </dependency>
