The project consists of four components: a Keycloak authorization server, a messages-webapp (Spring MVC client using Authorization Code Flow), a messages-service (REST API resource server), and an archival-service (acting as both resource server and client using Client Credentials Flow). The post outlines each service's responsibilities, API endpoints, and role-based access rules, and covers how to export and import Keycloak realm configuration via Docker for reproducible setup. ## Full article daily.dev links to this article rather than hosting it.
