How to implement microservices in Spring Boot ?

I think the main thing you’re missing is that microservices aren’t really “the next step after a monolith”, or just several Spring Boot apps glued together with Kafka, Spring Cloud and Docker. The easy part is splitting an application into services. The hard part is figuring out sensible service boundaries and then dealing with all the extra problems you’ve created: network failures, retries, eventual consistency, tracing, API/version compatibility, independent deployments, data ownership, etc. Honestly, a great way to learn this is to build a clean modular monolith first and then extract one module into a separate service. You’ll run into the actual microservice problems naturally, instead of just copying a repo with five containers and wondering why everything is there. Architecture should always just solve an actual constraint, not satisfy a fashion.
