{}We are transitioning from the current monolithic WildFly-based deployment to a lightweight and modular architecture. This involves deploying Spring Boot microservices as executable JARs managed by systemd, serving UI bundles via Nginx, and automating deployments via CI/CD.

This migration will significantly enhance scalability, observability, deployment speed, and system maintainability.

---

Acceptance Criteria:

• All backend services built as executable JARs and deployed via systemd

• Nginx configured as a reverse proxy for APIs and static host for UIs

• Domain routing and SSL termination via Nginx

• CI/CD pipeline updated to handle backend & frontend deployment

• Jenkins/GitHub Actions enabled for service restart & file rsync

• MySQL and Redis installed and configured

• All DBs and users created and privileges granted

• ELK or journald-based logging operational

• Migration documentation created for reproducibility
