๐ณAmazon ECS vs AWS Fargate๐ข
These two are not rivals so much as layers: ECS is the orchestrator, while Fargate is a serverless compute engine ECS can run tasks on instead of EC2.

๐ณAmazon ECS
- โFull control over the underlying EC2 instances
- โOften cheaper for steady, predictable workloads
- โFine-grained tuning of instance types and placement
- โReuse reserved or spot instances for savings
๐ขAWS Fargate
- โNo servers to patch, scale or manage
- โPay only for the vCPU and memory tasks use
- โFaster to launch with far less operational overhead
- โScales tasks up and down automatically
Verdict
Run ECS on EC2 for steady workloads where you want cost control and tuning. Run ECS on Fargate when you want serverless simplicity and no infrastructure to babysit.
Frequently asked
Is ECS different from Fargate?+
Yes, ECS is the orchestrator; Fargate is one compute option ECS uses instead of EC2.
Which is cheaper?+
EC2-backed ECS is usually cheaper for steady loads; Fargate wins on bursty or unpredictable usage.
Do I still configure ECS with Fargate?+
Yes, you define ECS task definitions and services either way; Fargate just removes server management.
