Fargate bills per vCPU-second and GB-second, not per task hour. In us-east-1 a 0.25 vCPU / 0.5 GB task runs ~$9/mo; a 4 vCPU / 16 GB task ~$145/mo. Prefer arm64 + C9g/C8g when moving steady-state to ECS on EC2.

As of May 8, 2026, Lambda bills INIT time on cold paths (pricing change live since Aug 1, 2025), API Gateway REST integrations time out at 29 seconds, and picking ALB vs NLB still determines whether TLS termination and routing live on the edge.

API Gateway REST integrations still max out at 29 seconds—if your Lambda keeps retrying a 35-second partner HTTP call without a bounded circuit, you burn capacity and duplicate side effects instead of failing fast.
