Design Patterns in Microservices

Microservices is a distinctive method of developing software systems that try to focus on building single-function modules with well-defined interfaces and operations.

Microservices have many benefits for Agile and DevOps teams.

The goal of microservices is to increase the velocity of application releases, by decomposing the application into small autonomous services that can be deployed independently. A microservices architecture also brings some challenges.

The design patterns shown here can help mitigate these challenges.

Below are the Micro-services Design Patterns:

 Decomposition Patterns:

  • Decompose by Business Capability
  • Decompose by Subdomain
  • Decompose by Transactions
  • Strangler Patterns
  • Bulkhead Pattern
  • Sidecar Pattern

 Integration Patterns:

  • API Gateway pattern
  •  Aggregator Pattern
  •  Proxy Pattern
  •  Gateway Routing Pattern
  •  Chained Microservice Pattern
  •  Branch Pattern
  •  Client-Side UI Composition Pattern 

Database Pattern:

  •  Database per Service
  •  Shared Database Per Service
  •  CQRS
  •  Event Sourcing
  •  Saga Pattern 

Observability Patterns:

  •  Log Aggregation
  •  Performance Metrics
  • Distributed Tracing
  •  Health Check

 Cross-Cutting Patterns:

  • External Configuration
  • Service Discovery Pattern
  •  Circuit Breaker Pattern
  •  Blue-Green Deployment Pattern
