Unzip hazelcast-_version_.zip file
Add hazelcast.jar file into your classpath
Hazelcast is pure Java. JVMs that are running Hazelcast will dynamically cluster. Although by default Hazelcast will
use multicast for discovery, it can also be configured to only use TCP/IP for environments where multicast is not
available or preferred (Click here for more info). Communication among
cluster members is always
TCP/IP with Java NIO beauty. Default configuration comes with 1 backup so if one node fails, no data will be lost.
It is as simple as usingjava.util.{Queue, Set, List, Map}. Just add the hazelcast.jar into your
classpath and start coding.
