Divide and Conquer Send Forth the Microservices
summary
Builds two Java microservices with Spring Boot (service1 on 8081, service2 on 8080), a MongoDB container seeded with ~10,000 Goodreads books, and a reactive WebClient between them. Shows domain mapping, a reactive repository, Dockerfiles and a docker-compose.yml that brings DB + service1 + service2 up and down, and demonstrates successful GETs for all books and single-book by id. Covers swapping localhost for container hostnames, rebuilding jars with Maven, and notes next steps like polyglot stores and Kubernetes.
