WPT 01Why Patterns Matter
Microservices architecture introduces complexity that requires proven patterns to manage effectively. These patterns help solve common challenges in distributed systems.
WPT 02Communication Patterns
API Gateway
A single entry point for all client requests:
- Handles routing and composition
- Implements cross-cutting concerns
- Enables rate limiting and authentication
Service Mesh
Dedicated infrastructure layer for service-to-service communication:
- Handles load balancing
- Provides observability
- Enables mTLS encryption
WPT 03Data Management Patterns
Database per Service
Each service owns its data:
- Enables independent scaling
- Allows technology diversity
- Requires careful coordination
Saga Pattern
Manage distributed transactions:
- Choreography-based sagas
- Orchestration-based sagas
- Compensation logic for failures
WPT 04Resilience Patterns
Circuit Breaker
Prevent cascade failures:
- Monitor for failures
- Open circuit when threshold exceeded
- Allow periodic tests to restore
Bulkhead
Isolate failures:
- Separate thread pools per service
- Limit concurrent requests
- Prevent resource exhaustion
WPT 05Conclusion
These patterns provide a foundation for building robust microservices. Apply them thoughtfully based on your specific needs.
