Code Example
Provided
Context
Choosing between microservices patterns for our scaling needs
Implementation Steps (5)
1Define service boundaries based on domain contexts
2Create API contracts between services
3Implement service discovery mechanism
4Set up inter-service communication (REST/gRPC)
5Deploy independent CI/CD pipelines per service
Benefits (4)
  • +Independent scaling of services
  • +Technology flexibility per service
  • +Fault isolation prevents cascade failures
  • +Faster deployments with smaller codebases
Tradeoffs (4)
  • ~Increased operational complexity
  • ~Network latency between services
  • ~Data consistency challenges
  • ~Requires mature DevOps practices
Code Example
// Service Registry Pattern
const serviceRegistry = new ServiceRegistry();

// Register microservice
serviceRegistry.register({
  name: 'user-service',
  host: 'localhost',
  port: 3001,
  healthCheck: '/health'
});

// Discover and call service
const userService = await serviceRegistry.discover('user-service');
const users = await userService.get('/users');
