Resilient Java Systems in Production - Hazelcast x London Java Community

### Modern Java systems don’t fail all at once. They fail under load, during warmup, and sometimes days after a “successful” zero-downtime deployment.

Join us for an evening focused on real-world resilience in production Java systems, from JVM performance stability to the hidden risks of mixed-version state during rolling upgrades.
Come for the talks, stay for the conversations. Food, drinks, swag, and a LEGO® raffle included.

### Special Guest: Simon Ritter

Java Champion and Deputy CTO at Azul, Simon Ritter shares how to make JVM performance more resilient by reducing latency risk from GC, warmup, and JIT behaviour without changing application code.

### Hazelcast Session

Zero-downtime rolling upgrades in distributed Java systems are hard when multiple versions of the same service and data model must run concurrently and share state. Using Hazelcast and Hazelcast Compact Serialization, we’ll show practical Java examples and tests that demonstrate how mixed versions behave and how to make those upgrades resilient in real systems.

### What’s in Store?

• Two technical talks on resilience in production Java systems
• Food & drinks included
• Swag + LEGO® raffle
• Networking with the local Java community
