Can you list the main microservice design patterns?

The main patterns of microservices design include:

• API Gateway — a single entry point for all clients that routes requests to the appropriate microservices.
• Service Discovery — a mechanism for automatically discovering microservice addresses in a dynamic environment.
• Circuit Breaker — protection against cascading failures, disabling calls to non-operational services.
• Saga — a pattern for managing distributed transactions through a sequence of local transactions with compensations.
• CQRS (Command Query Responsibility Segregation) — separation of read and write operations for optimization and scaling.
• Event Sourcing — storing state through a sequence of events, which simplifies auditing and recovery.
• Bulkhead — resource isolation to prevent failure propagation between services.

These patterns help build fault-tolerant, scalable, and manageable microservice architectures.
