Day 6: Shared Database (Interim)
The Shared Database pattern lets several services temporarily read and write the same physical database while their business logic already lives in separate service codebases.
The Shared Database pattern lets several services temporarily read and write the same physical database while their business logic already lives in separate service codebases.
Database per Service means every microservice owns a private datastore that no other service can read or write directly.
Service per Team means every service boundary has exactly one cross-functional team that owns it end to end: code, database, pipeline, production operation, and on-call.
A self-contained service answers a client request using only its own code and its own local data.
Decompose by Subdomain uses Domain-Driven Design (DDD) to split a large business domain into subdomains (Core, Supporting, Generic) and gives each one its own bounded context, its own model, and usually its own service.
