How do you migrate your Kafka cluster while still allowing full user traffic?
Recently, Wix migrated its self-hosted, 60B events per day Kafka clusters, to a managed Kafka platform.
The classic approach would be to perform this transition when all incoming traffic is removed from the data center.
But draining an entire data-center for an undetermined period of time, until all 2000 services complete the switch was too risky for us.
This talk is about how we gradually migrated all of our Kafka consumers and producers with 0 downtime while they continued to handle regular traffic. You will learn practical steps you can take to greatly reduce the risks and speed up the migration timeline.
