In order to run a task, we will demonstrate how to override the default Capacity Provider strategy with Fargate & Fargate Spot, both with a weight of 1, and to divide tasks equally among Fargate & Fargate Spot.

In order to demonstrate a cost breakdown between the tasks running on Fargate and Fargate Spot, we left the tasks running for a day.

In this blog post, we have demonstrated how to utilize CircleCI to deploy and manage ECS tasks and run applications in a cost-effective serverless approach by using Fargate Spot.
