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
