Question

Accepted Answer

Design patterns in microservices architecture help in solving common problems and improving scalability, maintainability, and flexibility.

Service Registry pattern - used for service discovery and registration, such as Netflix Eureka
Circuit Breaker pattern - prevents cascading failures by failing fast and providing fallback mechanisms, like Hystrix
API Gateway pattern - acts as a single entry point for clients to access multiple services, for example, Zuul
Saga pattern - manages distributed transactions across multiple services to maintain data consistency
Event Sourcing pattern - stores all changes to application state as a sequence of events, ensuring auditability and traceability
