 ## Cluster
 
-A `cluster` is simply an EKS cluster. EKS Blueprints provides for customizing the compute options you leverage with your `clusters`. The framework currently supports `EC2`, `Fargate` and `BottleRocket` instances. It also supports managed and self-managed node groups. To specify the type of compute you want to use for your `cluster`, you use the `managed_node_groups`, `self_managed_nodegroups`, or `fargate_profiles` variables.

+We rely on [`terraform-aws-modules/eks/aws`](https://registry.terraform.io/modules/terraform-aws-modules/eks/aws/latest) to configure `clusters`. See our [examples](getting-started.md) to see how `terraform-aws-modules/eks/aws` is configured for EKS Blueprints.
