5 Microservices Design Patterns Every DevOps Team Should Know

Blog By Sep 14, 2023 No Comments

Understanding and applying microservices design patterns can help you design more scalable, reliable and maintainable applications. Here are the 5 key microservices design patterns that every DevOps team should know:

  • API Gateway pattern – The API gateway serves as a single entry point for all client requests. It routes requests to the appropriate microservice and aggregates responses. It also handles concerns like authentication, monitoring and rate limiting. It provides a unified API for clients.
  • Database per service pattern – Each microservice owns its own database, ensuring loose coupling and high cohesion. This allows each microservice to use the optimal database type and scale independently.
  • Circuit breaker pattern – It prevents a network or service failure from cascading to other services. When a failure is detected, the circuit breaker trips and prevents further calls to the failing service. It periodically retries the service and closes the circuit when the service is available again.
  • Event-driven pattern – Services publish events when their state changes. Other services subscribe to these events and update their state accordingly. This ensures data consistency in an asynchronous and decoupled manner.
  • Saga pattern – A saga is a sequence of local transactions where each transaction updates data within a single service. If a transaction fails, compensating transactions are executed to undo the impact. This pattern helps manage distributed transactions.

These patterns help with concerns like scalability, fault tolerance, distributed data management and inter-service communication. Though each pattern has its trade-offs, when applied judiciously based on your application’s needs, they can help you build robust and resilient microservices applications.

Hope this overview of the 5 key microservices design patterns is helpful!
