AWS Fargate is a serverless compute engine that allows you to run containers without having to manage servers or clusters. With Fargate, you specify your application's resource needs and AWS handles provisioning the infrastructure required to run the containers. This removes the need to choose server types, decide when to scale resources, or optimize cluster packing. You pay only for the resources used by your containers. Fargate provides isolation at the individual task/pod level so containers don't share underlying resources. It works with both Amazon ECS and EKS, allowing containerized applications to be deployed with Fargate as the compute provider.
