microservices-patterns

What problem does it solve?

This Skill addresses the complexities of building and managing distributed systems. It helps you effectively decompose monoliths, manage inter-service communication, handle distributed data, and build resilient microservices that can withstand failures, ensuring your applications are scalable and robust.

Core Features & Use Cases

• Service Decomposition: Strategies for breaking down applications by business capability or subdomain.
• Communication Patterns: Implement synchronous (REST, gRPC) and asynchronous (event-driven, message queues) inter-service communication.
• Data Management: Master "database per service" and the Saga pattern for distributed transactions.
• Resilience Patterns: Apply Circuit Breaker, Retry with Backoff, and Bulkhead to build fault-tolerant systems.
• Use Case: Decompose a large, monolithic e-commerce platform into independent microservices, ensuring robust communication and data consistency across services.

Quick Start

Example: Service Decomposition by Business Capability

Order Service

class OrderService: async def create_order(self, order_data: dict) -> Order: order = Order.create(order_data) await self.event_bus.publish(OrderCreatedEvent(...)) return order

Payment Service (separate service)

class PaymentService: async def process_payment(self, payment_request: PaymentRequest) -> PaymentResult: result = await self.payment_gateway.charge(...) if result.success: await self.event_bus.publish(PaymentCompletedEvent(...)) return result
