Blue/green deployment refers to a software technique that can be used to reduce or even eliminate systems downtime and its associated business risk by deploying two mirrored production environments referred to as Blue and Green.
Starting from version 3.12, Hazelcast IMDG Enterprise provides a client connection strategy that allows for client connections to be rerouted to a different cluster without requiring a client network configuration update and restart. This feature can be used to manually redirect client traffic to a newly updated cluster, and should any problems be found in that updated clusters, clients can be redirected back to the original production cluster with no downtime. This feature also can automatically redirect client traffic to a different cluster during a disaster recovery scenario. This white paper will walk you through these deployments, the features, and several use cases.
