EDB Summer Academy

Most HA setups look great until something goes wrong. This session covers the core architectures, failure modes, and hard-won lessons that separate robust high availability from a false sense of security.

We dig into the scenarios teams most often overlook: replication lag during a failover, split-brain risks, fencing a demoted primary, and why automated failover can make an outage worse if not done carefully. Add in the observability and testing practices that give you real confidence in your setup, and you leave with a clear path from theory to production reality.
