Active / Active Architecture
Active / Active architecture example for SRM.
In an Active / Active scenario, your producers can be load balanced to either your primary or secondary cluster. SRM is configured to replicate topics bidirectionally between both clusters. What makes this architecture Active / Active, is the fact that you now have consumers reading from both clusters at the same time, essentially acting like a cross-cluster consumer group. In case of a disaster the VIP or load balancer directs the producers to the secondary cluster and the secondary cluster consumer group is still able to process messages.While the primary cluster is down, your producers are still able to ingest and your consumers are still able to process messages. This results in a 0 downtime and hands-off failover in case of a disaster. Once the primary cluster is back online, SRM automatically takes care of synchronizing both clusters and your primary consumer group resumes processing messages.
