Understanding Service Decomposition Patterns

When splitting monolithic applications into microservices, deciding where to draw service boundaries becomes the most critical architectural decision. This detailed examination covers decomposition strategies based on business capabilities, subdomain analysis, and transaction boundaries. We analyze actual migration scenarios, common pitfalls in granularity decisions, and practical approaches to identifying appropriate service scopes. The discussion includes database separation challenges, shared data handling strategies, and techniques for managing distributed transactions without compromising service autonomy.
