Open Liberty, the open-source implementation of Eclipse MicroProfile and Java EE from IBM, and the foundation of the WebSphere Liberty app server, is adopting Hazelcast’s in-memory data grid (IMDG) as its preferred caching provider, the two companies announced. The IMDG will be used for a session replication module based on JCache.

Session replication is a high-availability feature that allows another application server to continue the user’s browser session without interruption.
