Spring Cloud: API gateway upgrade & configuration in the cloud

on YouTube ↗54m

" summary

Compares Zuul vs the new reactive Spring Cloud Gateway (reactive) and shows how routes, predicates and filters move from Java code into YAML so gateways can change without rebuilds. Demonstrates Spring Cloud Config + Bus (Git + Rabbit/Kafka) storing configs in Git, sending refresh events, and using @RefreshScope to hot-swap bean properties. Claims zero-downtime config changes at scale (example: 40 billion requests/day, ~500k/sec), explains tradeoffs, and reports this setup runs in production for their projects.
