Modern enterprises frequently find themselves constrained by monolithic codebases that resist agile deployment rhythms. In this deep dive, we break down the practical migration path our engineering teams use to refactor critical monoliths into scalable microservices orchestrated via Kubernetes.
Phase 1: Domain-Driven Decomposition
Before launching containers, decouple the database layer and isolate clear business domain boundaries. Identify independent services that can be extracted with minimal circular dependency.
Phase 2: Automated CI/CD & Observability
A successful container rollout requires end-to-end continuous deployment pipelines and real-time observability utilizing Prometheus and Grafana dashboards to monitor pod health, latency spikes, and automatic autoscaling triggers.
