Serverless computing on AWS reduces operational overhead. Follow these best practices for success.

Architecture Design

Use Lambda for compute, API Gateway for routing, and DynamoDB for storage. Implement event-driven patterns.

Cost Optimization

Provisioned concurrency for predictable latency, optimize cold starts, and monitor with CloudWatch.

  • Set timeouts appropriately.
  • Use layers for shared code.
  • Implement dead letter queues.

Security

IAM roles with least privilege, encrypt data at rest and in transit, and use Cognito for authentication.

Testing and Deployment

Unit test functions, integration test with SAM, and CI/CD with CodePipeline.

Serverless scales effortlessly. Go serverless.
