Micro Services

• Sync Patterns:
  • API Gateway
  • Load Balancers
• Async Patterns
  • SQS
  • Kinesis
  • SNS
  • Lambda triggers (S3)
• Challenges with microservices:
  • repeated overhead for creating each new microservice.
  • Issues with optimizing server density/utilization.
  • Complexity of running multiple versions of multiple microservices simultaneously.
  • Proliferation of client-side code requirements to integrate with many services.
• Some challenges are solved by Serverless patterns:
  • API Gateway, Lambda scale automatically and you per usage.
  • You can easily clone API, reproduce environments.
  • Generated client SDK through Swagger integration for the API Gateway.
