# AWS EKS Cluster with Fargate profiles
|
||||
|
||||
Configuration in this directory creates EKS cluster with Fargate profiles in two different ways:
|
||||
|
||||
- Using a root module, where EKS Cluster and Fargate profiles should be created at once. This is the default behaviour for most users.
|
||||
- Using `modules/fargate` submodule where Fargate profiles should be attached to the barebone EKS Cluster.
|
||||
- Using `modules/fargate` submodule where Fargate profiles should be attached to the existing EKS Cluster.
