Keycloak, Spring Authorization Server & Microservices Security
A single microservice validating its own users doesn't scale to ten microservices. This chapter is centralizing authentication with Keycloak (or your own Spring Authorization Server) across a whole system.
Learning objectives
- Beginner: Explain why centralizing authentication matters once you have more than one microservice.
- Intermediate: Configure a Spring Boot resource server to validate tokens issued by Keycloak.
- Advanced: Reason about when to run your own Spring Authorization Server instead of an off-the-shelf identity provider like Keycloak.
