From Traditional to GitOps: A Tale of Modernizing Two Goverment Institutions in One Year
summary
Two Guatemalan government systems move from Docker and Java EE monoliths to a staged cloud strategy inside a year, facing a data residency in Guatemala constraint and target concurrency of 1,000–5,000 concurrent users. Work includes on‑premises GitLab CI/CD, lift from Docker monolith to Kubernetes, and observability with Prometheus, Grafana and Linkerd plus SonarQube for code quality. Approach uses PMI phases, micro‑product migrations, satellite services before breaking monoliths, mandatory live documentation and training; first migration succeeds, second requires deeper cultural change.
