Brand new Proximus microservices architecture in production

on YouTube ↗51m

" summary

Proximus migrates a decade-old monolith into a phased microservices platform and ships into production using Spring Boot, Spring Cloud (Eureka, Hystrix, Turbine), HAL hypermedia, Zipkin tracing, ELK logging, Pact consumer-driven contracts and Cloud Foundry; provisioning hundreds of JBosses once takes five days and causes major pain, the first production rollout is a two-week war room until monitoring and circuit-breakers expose failures, and about 50 microservices run with automated tests, API docs from Spring REST Docs, and a gateway aggregating HAL indexes.
