Practice next
- Adopt SAM or CDK serverless constructs.
- Standardize structured JSON logging.
- Set account-level Lambda concurrency caps.
- Add AWS X-Ray tracing: Active on function.
- Export shared authorizer Lambda for all APIs.
Remember
SAM/CDK for repeatable serverless. Shared layers for common code. Org guardrails on concurrency.
