Upgrading software without downtime is one of the most important factors in systems that are highly-available. Users do not tolerate downtime from maintenance windows and expect their applications to be online all the time. Hazelcast IMDG 3.8 introduced the ability to do online upgrades without any maintenance downtime. It means that business transactions can be processed while the software is being upgraded—keeping business users happy.

Join Hazelcast Core Team Lead, Tom Bujok, in a deep dive overview of the Hazelcast IMDG feature Rolling Upgrades to learn how you can keep your system running continuously while upgrading IMDG servers and clients.
