Refactor Java EE application Microservices and Containers

on YouTube ↗49m

" summary

Shows a Java EE7 monolith (WAR) refactored into user/catalog/order microservices each packaged as Docker images and run in WildFly containers, with service registration via Zookeeper service registry (alternatives: snoop, Kubernetes). Uses the Docker Maven plugin to build images and start containers; code size increases due to duplication but services deploy faster and scale independently. Covers patterns (aggregator, proxy, chain, branch), async messaging vs REST, CI/CD/automation needs, and real-world scale concerns (Netflix: ~50 billion daily calls, ~35% evening traffic) and failure handling.
