vCPU-hours and memory-hours for serverless containers.
Oversized Fargate tasks quietly overpay on vCPU and memory every second they run. Right-size the task and scale count with demand. Compare a self-managed cluster on the Kubernetes cost calculator and container hosting calculator.
Free AWS Fargate cost calculator — tasks, vCPU and memory per task to your real monthly container bill.
Per vCPU-hour (about $0.04048) and per GB-hour of memory (about $0.004445), billed per second with a one-minute minimum. You choose vCPU and memory per task, and pay only while tasks run — there are no idle EC2 hosts underneath.
Fargate removes server management and is cheaper for spiky or low-utilisation workloads because you pay per task-second. For high, steady utilisation, running your own EC2 hosts under ECS/EKS can be cheaper per container. It is a utilisation question.
