Experiences and Lessons Learned Building a Multi-Cloud Spring Boot Backend
summary
Multi‑cloud Spring Boot backend runs on Oracle Cloud and Azure (Tanzu and on‑prem BYO supported) and installs via Terraform + Ansible into Kubernetes with Oracle Database, Eureka, Spring Config, Conductor, Kafka, Vault, Coherence, Prometheus/Grafana/Loki and optional Jaeger/OpenTelemetry. Installer uses a mono‑repo, nightly builds and automated tests; platform provides a CLI and a VS Code extension and an admin service that builds native image default containers with JVM fallback. Lessons include AZ and shape variability, surprising 10,000 DB connections at scale, and the deliberate choice of no service mesh.
