What Is AWS EKS?
AWS EKS, a managed service, eliminates the need to install, administer, and maintain your own Kubernetes control plane on Amazon Web Services (AWS). Kubernetes simplifies containerized app scaling, deployment, and management.
How it Works?
AWS Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes solution for on-premises data centers and the AWS cloud. The Kubernetes control plane nodes in the cloud that are in charge of scheduling containers, controlling application availability, storing cluster data, and other crucial functions are automatically managed in terms of scalability and availability by AWS EKS.
You can benefit from all of AWS infrastructure’s performance, scalability, dependability, and availability with Amazon EKS. You can also integrate AWS networking and security services. When deployed on-premises on AWS Outposts, virtual machines, or bare metal servers, EKS offers a reliable, fully supported Kubernetes solution with integrated tools.
AWS EKS advantages
Integration of AWS Services
Make use of the integrated AWS services, including EC2, VPC, IAM, EBS, and others.
Cost reductions with Kubernetes
Use automated Kubernetes application scalability and effective computing resource provisioning to cut expenses.
Security of automated Kubernetes control planes
By automatically applying security fixes to the control plane of your cluster, you can guarantee a more secure Kubernetes environment.
Use cases
Implement in a variety of hybrid contexts
Run Kubernetes in your data centers and manage your Kubernetes clusters and apps in hybrid environments.
Workflows for model machine learning (ML)
Use the newest GPU-powered instances from Amazon Elastic Compute Cloud (EC2), such as Inferentia, to efficiently execute distributed training jobs. Kubeflow is used to deploy training and inferences.
Create and execute web apps
With innovative networking and security connections, develop applications that operate in a highly available configuration across many Availability Zones (AZs) and automatically scale up and down.
Amazon EKS Features
Running Kubernetes on AWS and on-premises is made simple with Amazon Elastic Kubernetes Service (AWS EKS), a managed Kubernetes solution. An open-source platform called Kubernetes makes it easier to scale, deploy, and maintain containerized apps. Existing apps that use upstream Kubernetes can be used with Amazon EKS as it is certified Kubernetes-conformant.
The Kubernetes control plane nodes that schedule containers, control application availability, store cluster data, and perform other crucial functions are automatically scaled and made available by Amazon EKS.
You may run your Kubernetes apps on AWS Fargate and Amazon Elastic Compute Cloud (Amazon EC2) using Amazon EKS. You can benefit from all of AWS infrastructure’s performance, scalability, dependability, and availability with Amazon EKS. It also integrates with AWS networking and security services, including AWS Virtual Private Cloud (VPC) support for pod networking, AWS Identity and Access Management (IAM) integration with role-based access control (RBAC), and application load balancers (ALBs) for load distribution.
Managed Kubernetes Clusters
Managed Control Plane
Across several AWS Availability Zones (AZs), AWS EKS offers a highly available and scalable Kubernetes control plane. The scalability and availability of Kubernetes API servers and the etcd persistence layer are automatically managed by Amazon EKS. To provide high availability, Amazon EKS distributes the Kubernetes control plane throughout three AZs. It also automatically identifies and swaps out sick control plane nodes.
Service Integrations
You may directly manage AWS services from within your Kubernetes environment with AWS Controllers for Kubernetes (ACK). Building scalable and highly available Kubernetes apps using AWS services is made easy with ACK.
Hosted Kubernetes Console
For Kubernetes clusters, EKS offers an integrated console. Kubernetes apps running on AWS EKS may be arranged, visualized, and troubleshooted in one location by cluster operators and application developers using EKS. All EKS clusters have automatic access to the EKS console, which is hosted by AWS.
EKS Add-Ons
Common operational software for expanding the operational capability of Kubernetes is EKS add-ons. The add-on software may be installed and updated via EKS. Choose whatever add-ons, such as Kubernetes tools for observability, networking, auto-scaling, and AWS service integrations, you want to run in an Amazon EKS cluster when you first launch it.
Managed Node Groups
With just one command, you can grow, terminate, update, and build nodes for your cluster using AWS EKS. To cut expenses, these nodes can also make use of Amazon EC2 Spot Instances. Updates and terminations smoothly deplete nodes to guarantee your apps stay accessible, while managed node groups operate Amazon EC2 instances utilizing the most recent EKS-optimized or customized Amazon Machine Images (AMIs) in your AWS account.
AWS EKS Connector
Any conformant Kubernetes cluster may be connected to AWS using AWS EKS, and it can be seen in the Amazon EKS dashboard. Any conformant Kubernetes cluster can be connected, including self-managed clusters on Amazon Elastic Compute Cloud (Amazon EC2), Amazon EKS Anywhere clusters operating on-premises, and other Kubernetes clusters operating outside of AWS. You can access all linked clusters and the Kubernetes resources running on them using the Amazon EKS console, regardless of where your cluster is located.
