How We Transformed a Monolithic System into Scalable Microservices

The article details a three‑phase migration of a large monolithic Java application—splitting its database, refactoring code for multi‑datasource and custom transaction handling, and decomposing the application into nine independent services—while addressing data safety, routing, testing, and deployment risks to achieve a robust microservice architecture.
