This article highlights some cost-saving measures that can be implemented to minimize the expense of running Elastic Container Service (ECS) on Fargate by AWS.
The author suggests minimising resource allocation for development environments, which can lead to significant cost savings. They set the minimum configuration of 256 (.25 vCPU), 512 MiB for their development environment.
Fargate Spot instances are up to 70% cheaper than standard Fargate instances; thus, by using Fargate Spot for development environments, costs can be reduced.
Stopping tasks during non-working hours in development environments can significantly reduce Fargate costs, and this can be done using EventBridge and Lambda to schedule task stop and start times.
Migrating from x86_64 architecture to Arm architecture can reduce; up to 20% Fargate pricing while maintaining high performance.
In the CI/CD workflow, docker buildx enables efficient multi-architecture image builds, making the infrastructure more flexible.
The article suggests utilizing Compute Savings Plans, as this allows committing to a consistent amount of compute usage (measured in USD/hour) over a 1- or 3-year period, offering significant discounts across EC2, Lambda, and Fargate.
By implementing these cost optimization strategies, significant reductions in ECS on Fargate costs can be achieved while maintaining system stability.
