Serverless containers, or containers on instances you run yourself.
Pick Fargate for zero infrastructure management, spiky workloads, or simply getting started — you pay per vCPU-second the task requests and AWS owns the host. Pick the EC2 launch type for large, steady, high-utilisation workloads that must be price-optimised, or anything needing GPUs, privileged containers, daemon workloads, or custom AMIs. The deciding factor is steady-state utilisation and host control: high predictable load plus any host-level need points to EC2; everything else favours Fargate.
Answer the questions — the helper scores both the options against the sourced table below and shows its reasoning. A heuristic, not an oracle: the verdict above stays the authority.
| Criterion | Fargate | EC2 launch type |
|---|---|---|
| Host management | AWS — no provisioning, patching or scaling | You — instance choice, config, maintenance |
| Pricing model | Per-second, on the vCPU + memory the task requests | The EC2 instances you run — used or idle |
| Cost at steady high load | Less efficient — billed per task, not per packed host | Cheaper — pack instances to high utilisation |
| GPU support | Not supported | Yes — EC2 GPU instances + the GPU-optimized AMI |
| Privileged / daemon tasks | No — privileged and the DAEMON strategy unsupported | Yes — privileged containers and DAEMON tasks |
| Host access | None — no SSH, no custom AMI | Full — SSH, custom AMIs, instance-type choice |
| Networking modes | awsvpc only — one ENI per task | awsvpc, bridge or host |
| Isolation | Each task in its own kernel / CPU / memory boundary | Tasks on an instance share that instance's kernel |
