Fargate
AWS Fargate — commitment brief
Data sourced: March 2026. Verify current figures at the AWS Pricing Calculator.
Coverage summary
AWS Fargate (for both Amazon ECS and Amazon EKS) is covered by Compute Savings Plans (1-yr and 3-yr terms), which provide up to 52% savings on Fargate vCPU and memory charges versus on-demand pricing (approximately 20% for a 1-year term, up to 52% for a 3-year term). Fargate became eligible for Compute Savings Plans in 2020, with EKS Fargate support added later the same year. The Compute Savings Plan is a single hourly spend commitment that automatically applies across Fargate, EC2, and Lambda — there are no Fargate-only Reserved Instances. Fargate Spot (for ECS) is not eligible for Compute Savings Plans.
What is covered: Fargate vCPU-hour charges and Fargate GB-memory-hour charges for tasks running on both Amazon ECS (EC2 launch type excluded — ECS with Fargate launch type only) and Amazon EKS Fargate profiles.
What is not covered: ECS tasks using the EC2 launch type (those are covered by EC2 RIs, not Fargate Savings Plans), Fargate Spot task charges (Spot pricing model; not eligible for Savings Plans), EKS control plane costs ($0.10/cluster-hour; not eligible), data transfer, Elastic Load Balancer charges, and EFS/EBS storage attached to tasks.
Savings Plan types
AWS Fargate is covered exclusively by Compute Savings Plans — the most flexible Savings Plan type, which applies a single hourly spend commitment across Fargate (ECS + EKS), EC2 instance compute, and Lambda in any region. Fargate savings (~20% for 1-yr, up to ~52% for 3-yr) are lower than EC2 savings (up to 66%) under the same plan, but higher than Lambda savings (up to 17%). There are no Fargate-specific Reserved Instances.

Regional availability
Commitment scope: Region-flexible — Compute Savings Plans apply automatically across Fargate (ECS and EKS), EC2, and Lambda in any supported AWS region; a single plan covers usage regardless of which region the workload runs in.
Available in all commercial AWS regions where Fargate is offered. Compute Savings Plans automatically apply to Fargate usage across any region without requiring per-region commitments.
Partition notes: AWS Fargate is available in GovCloud (us-gov-) regions. Compute Savings Plans can cover GovCloud Fargate usage, but must be purchased from a linked standard AWS account — they cannot be purchased directly from GovCloud accounts. Savings Plans are not available in China (cn-) regions.
⚠️ Regional and partition availability varies by instance type. Always verify at the AWS Pricing Console before purchasing.
Archera
AWS Fargate is within Archera's commitment management scope via Compute Savings Plan coverage. Archera can automate Compute Savings Plan purchases that cover Fargate usage (alongside EC2 and Lambda usage under the same plan), monitor Fargate vCPU and memory spend against the hourly commitment, and wrap commitments in a GRI/GSP — eliminating downside risk on over-commitment while preserving the Savings Plan discount. Because Fargate, EC2, and Lambda share a single Compute Savings Plan, Archera optimizes the aggregate commitment across all three services.
