AWS EKS: What is it?
Installing, managing, and maintaining your own Kubernetes control plane on Amazon Web Services (AWS) is no longer necessary with AWS EKS, a managed service. Scaling, deploying, and managing containerized apps is made easier using Kubernetes.
How Does It Operate?
For on-premises data centers and the AWS cloud, AWS Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes solution. AWS EKS automatically manages the scalability and availability of the Kubernetes control plane nodes in the cloud that are responsible for scheduling containers, managing application availability, storing cluster data, and other critical tasks.
With Amazon EKS, you can take use of all the performance, scalability, reliability, and availability of AWS infrastructure. AWS networking and security services can also be integrated. EKS provides a dependable, fully supported Kubernetes solution with integrated tools that can be installed on-premises on AWS Outposts, virtual machines, or bare metal servers.
Benefits of AWS EKS
Combining AWS Services
Utilize AWS services that are integrated, such as EC2, VPC, IAM, EBS, and others.
Using Kubernetes to cut costs
Reduce costs by utilizing efficient compute resource provisioning and automatic Kubernetes application scalability.
Automated Kubernetes control aircraft security
You may ensure a more secure Kubernetes environment by automatically applying security fixes to your cluster's control plane.
Use cases
Use in a range of hybrid environments
Manage your Kubernetes clusters and applications in hybrid environments, and run Kubernetes in your data centers.
Model machine learning (ML) workflows
To effectively complete distributed training tasks, use the newest GPU-powered instances from Amazon Elastic Compute Cloud (EC2), like Inferentia. Inferences and training are deployed via Kubeflow.
Develop and implement web applications
Create applications that run in a highly available configuration across numerous Availability Zones (AZs) and scale up and down automatically with creative networking and security connections.
Features of Amazon EKS
Amazon Elastic Kubernetes Service (AWS EKS) is a managed Kubernetes solution that makes it easy to run Kubernetes on AWS and on-premises. Containerized apps may be scaled, deployed, and maintained more easily with the help of an open-source platform called Kubernetes. Because Amazon EKS is certified Kubernetes-conformant, it can be deployed with existing apps that use upstream Kubernetes.
Amazon EKS automatically scales and makes accessible the Kubernetes control plane nodes that manage application availability, schedule containers, store cluster data, and carry out other essential tasks.
You can use Amazon EKS to execute your Kubernetes applications on AWS Fargate and Amazon Elastic Compute Cloud (Amazon EC2). With Amazon EKS, you can take use of all the performance, scalability, reliability, and availability of AWS infrastructure. Additionally, it connects with AWS networking and security services, including as application load balancers (ALBs) for load distribution, AWS Identity and Access Management (IAM) integration with role-based access control (RBAC), and AWS Virtual Private Cloud (VPC) support for pod networking.
Kubernetes Cluster Management
Control Plane
AWS EKS provides a scalable and highly available Kubernetes control plane across many AWS Availability Zones (AZs). Amazon EKS automatically manages the etcd persistence layer and the scalability and availability of Kubernetes API servers. Amazon EKS spreads the Kubernetes control plane across three AZs to achieve high availability. Additionally, it recognizes and replaces sick control plane nodes automatically.
Integrations of Services
AWS Controllers for Kubernetes (ACK) allow you to easily manage AWS services from within your Kubernetes environment. ACK makes it simple to create scalable and highly available Kubernetes applications with AWS services.
Kubernetes Console Hosted
EKS provides an integrated console for Kubernetes clusters. Cluster operators and application developers may use AWS EKS to organize, visualize, and troubleshoot Kubernetes apps in one place. The EKS console, hosted by AWS, is automatically accessible from every EKS cluster.
EKS Accessories
EKS add-ons are often used operational software to increase Kubernetes' operational capability. EKS can be used to install and update the add-on software. When you first build an Amazon EKS cluster, you can select the add-ons you want to use, such as Kubernetes tools for observability, networking, auto-scaling, and AWS service integrations.
Groups of Managed Nodes
Using AWS EKS, you may expand, terminate, update, and create nodes for your cluster with a single command. These nodes can also use Amazon EC2 Spot Instances to reduce costs. While managed node groups run Amazon EC2 instances using the most recent EKS-optimized or customized Amazon Machine Images (AMIs) in your AWS account, updates and terminations seamlessly decrease nodes to ensure your apps remain accessible.
Connector for AWS EKS
Using AWS EKS, any conformant Kubernetes cluster may be linked to AWS and displayed on the Amazon EKS dashboard. Any Kubernetes cluster that complies with the requirements can be linked, including self-managed clusters on Amazon Elastic Compute Cloud (Amazon EC2), on-premises Amazon EKS Anywhere clusters, and other Kubernetes clusters that are not hosted by AWS. No matter where your cluster is situated, you may use the Amazon EKS console to view all linked clusters and the Kubernetes resources that are operating on them.
