aws-compute-selection

name	aws-compute-selection
description	Choose AWS compute by workload shape and operational burden: Lambda (event/spiky), Fargate/App Runner (containers, no cluster ops), EKS (k8s/portability), EC2 (legacy/specific); design event-driven integration with idempotency and DLQs.

AWS Compute Selection

Workload	Compute
Event / spiky / short	Lambda
Long-running container, no cluster ops	Fargate / App Runner
Need k8s / portability	EKS
Legacy / specific OS	EC2

Match the shape; don't default to one. Serverless-first for variable load (mind cold starts + limits).

Integration

SQS (decouple), SNS/EventBridge (fan-out/route), Step Functions (orchestrate w/ retries). Every async consumer is idempotent + has a DLQ. No hand-rolled queues/pollers.
