Master microservices architecture patterns including service boundaries, inter-service communication, data management, and resilience patterns for building distributed systems. By Business Capability By Subdomain (DDD) Strangler Fig Pattern Synchronous (Request/Response) Asynchronous (Events/Messages) Database Per Service Saga Pattern Circuit Breaker Retry with Backoff Bulkhead - Decomposing monoliths into microservices - Designing service boundaries and contracts - Implementing inter-service communication - Managing distributed data and transactions - Building resilient distributed systems - Implementing service discovery and load balancing - Designing event-driven architectures - Organize services around business functions - Each service owns its domain - Example: OrderService, PaymentService, InventoryService - Core domain, supporting subdomains - Bounded contexts map to services - Clear ownership and responsibility - Gradually extract from monolith - New functionality as microservices - Proxy routes to old/new systems - REST APIs - gRPC - GraphQL - Event streaming (Kafka) - Message queues (RabbitMQ, SQS) - Pub/Sub patterns - Each service owns its data - No shared databases - Loose coupling - Distributed transactions - Compensating actions - Eventual consistency - Fail fast on repeated errors - Prevent cascade failures - Transient fault handling - Exponential backoff -...
