This is all done through the Fargate Profile, which will be discussed in detail in the following section.

Understanding how the AWS Fargate profile works

When considering how to integrate the Fargate service with EKS, the AWS team made a conscious decision not to make users update their existing K8s manifests to support Fargate. Instead, the profile identifies which namespaces and/or labels will be used to host Pods on Fargate, and no changes are required in the Pod definition. The following diagram illustrates how this process works:
