Section 15 - Serverless Architectures

Synchronous patterns: API Gateway, Load Balancers
Asynchronous 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 separate services
Solutions using serverless patterns:
- API Gateway and Lambda scale automatically and are pay per usage
- Can easily clone an API and reproduce the environments
- Generated client SDK via Swagger integration for API Gateway
