On-premise to Cloud and Kafka Version Upgrade
On-premise to cloud and Kafka version upgrade example architectures for SRM.
If you have an on-premises Apache Kafka cluster that you want to migrate to the cloud, not only do you have to migrate consumers and producers, you also have to migrate topics and their messages to the new cloud based cluster.
After you have set up replication through SRM, you only need to point your consumers to the new brokers before you can start processing messages from the cloud cluster. This approach ensures that the historical data kept in the on-premises Kafka cluster is migrated to the cloud cluster allowing you to replay messages directly from the cloud without having to go back to your on-premises cluster.
Once you have migrated your cluster, producers, and consumers to the cloud, you can use SRM to turn-around the replication direction and use the on-premises cluster as your DR cluster.
Kafka Version Upgrade
If you have to upgrade your Kafka cluster to a newer version and an in-place upgrade is not possible, you can use the same migration approach to provision a new cluster, use SRM to replicate all existing topics and messages before migrating your producers and consumers to interact with the new cluster.
