Most Spring Boot apps still store sessions locally — fine… until a node restarts or a region goes down.
In this walkthrough, we show how to:
Replace local HttpSession with Hazelcast Spring Session
Add cluster backups in a few lines of config
Enable Geo (/WAN) replication for cross-region resilience
Run active-active with failover
✅ No application code changes — just a dependency + configuration.
If you run Spring Boot and care about session resilience, this is a practical guide.
