ECS waste check
Oversized ECS Memory
oversized_ecs_memory
What it finds
Oversized ECS Memory: one of the ECS checks in the container optimization group. Checks in this group look for: container services that run with no work to do, oversized tasks, or observability settings out of proportion to the cluster.
Why it costs money
Tasks and clusters bill for the vCPU and memory they reserve, whether or not the containers use it.
How it is detected
Runs in the partner build and the paid hosted tiers.
AWS's own tools
AWS flags this too, under "Compute Optimizer recommendations for Amazon ECS services on Fargate".
Checked against the AWS documentation.
Where this check runs
This check ships in the partner build, for consultancies that scan client accounts, and in the paid hosted tiers.
