 In EKS, AWS is responsible for the reliability of the Kubernetes control plane. EKS runs Kubernetes control plane across three availability zones in an AWS Region. It automatically manages the availability and scalability of the Kubernetes API servers and the etcd cluster. 
 
-The responsibility for the data plane’s reliability is shared between you, the customer, and AWS. EKS offers three options for Kubernetes data plane. Fargate, which is the most managed option, handles provisioning and scaling of the data plane. The second option, managed nodes groups, handles provisioning, and updates of the data plane.

+The responsibility for the data plane’s reliability is shared between you, the customer, and AWS. EKS offers three worker node options for deploying the Kubernetes data plane. Fargate, which is the most managed option, handles provisioning and scaling of the data plane. The second option, managed nodes groups, handles provisioning, and updates of the data plane. And finally, self-managed nodes is the least managed option for the data plane. The more AWS-managed data plane you use, the less responsibility you have.
 
 [Managed node groups](https://docs.aws.amazon.com/eks/latest/userguide/managed-node-groups.html) automate the provisioning and lifecycle management of EC2 nodes. You can use the EKS API (using EKS console, AWS API, AWS CLI, CloudFormation, Terraform, or `eksctl`),   to create, scale, and upgrade managed nodes. Managed nodes run EKS-optimized Amazon Linux 2 EC2 instances in your account, and you can install custom software packages by enabling SSH access. When you provision managed nodes, they run as part of an EKS-managed Auto Scaling Group that can span multiple Availability Zones; you control this through the subnets you provide when creating managed nodes. EKS also automatically tags managed nodes so they can be used with Cluster Autoscaler.
