.NET Microservices Patterns

Service Decomposition

By Business Capability

E-Commerce Platform:
├── Catalog Service (products, categories, search)
├── Order Service (orders, order processing)
├── Payment Service (payment processing, refunds)
├── Inventory Service (stock management)
├── Notification Service (email, SMS, push)
├── Identity Service (authentication, users)
└── Gateway (API gateway, BFF)

Database Per Service

Each service owns its data store. No shared databases.
