Experiences using Grails in a microservice architecture

on YouTube ↗01h 22m

" summary

Grails runs as the lowest-layer REST resource framework while Spring Boot handles non-web consumers; a subscription service uses GORM with Cassandra, emits events to a broadcast channel, and relies on Spring Batch for compensation jobs. Shared code ships as plugins to an internal nexus and a thin Java jar for Spring Integration (dedupe filter, custom deserializer). CI/CD uses Bamboo plus Puppet skeletons for rolling zero‑downtime deploys. Logging uses a correlation id in Log4j MDC, aggregated in Splunk, with New Relic custom traces for per‑call timing.
