![]() ![]() As of publication, EKS is only running up to Kubernetes version 1.22, even though version 1.24 is already out. It's not available in all AWS regions, and its release velocity is slow. Availability and managementĪlthough EKS runs Upstream Kubernetes and is certified Kubernetes-conformant, it has some drawbacks. Key features to consider are availability, security and cost. The available features and the simplicity - or lack thereof - will push organizations one way or the other. When an organization must decide how it will deploy Kubernetes on AWS, choosing the right option comes down to the use case and specific development requirements. Admins will also have to patch and maintain everything by hand, which can be inconvenient in some cases. In this case, the control plane is visible and available to the users, who will be able to see components running on dedicated EC2 instances. Deploy with tools like kops, which help create and manage the Kubernetes cluster. This is a standard tool, regardless of the Kubernetes version.Īlternatively, IT teams can run a self-managed Kubernetes environment on an EC2 instance. Use kubectl to run actual commands against a Kubernetes cluster and manage the containerized resources within it. ![]() It can also make subsequent modifications when required. This third-party tool can provision an entire Kubernetes infrastructure, including the managed control plane and unmanaged worker nodes. When the Kubernetes control plane creates new pods, they will run as containers in Fargate without any Kubernetes node creation and configuration.Ī developer can deploy an EKS cluster using eksctl. With it, users can take advantage of the serverless platform for their Kubernetes data plane. AWS FargateĪWS Fargate is the managed service to create on-demand compute capacity for containers. Users need to click only a couple of buttons on the web console to add new nodes and update the OS or Kubernetes versions. With the EKS-managed node groups, EKS automatically creates and updates data-plane nodes. In addition, users need to handle the updating of the OS and Kubernetes version of the data-plane nodes. Then, the Kubernetes control plane assigns pods to the nodes and runs containers. When the EC2 VMs are up and running, they join the Kubernetes control plane. With the self-managed nodes, users need to create and manage nodes with manual configuration or via the AWS CloudFormation templates provided by EKS. For users, the EKS control plane is essentially a black box.įor the data plane, there are three options for EKS users: self-managed nodes, EKS-managed node groups and AWS Fargate. It also handles all the upgrades and patching. ![]() AWS automatically replaces any unhealthy nodes in order to maintain high availability. The entire management infrastructure runs behind the scenes, across multiple availability zones. ![]() With EKS, Amazon fully manages the control plane - including components like etcd and Kubernetes API server with integration to other AWS services, such as Identity and Access Management ( IAM). To choose between EKS and self-managed Kubernetes, carefully consider the benefits and drawbacks of each option. Eventually, however, Amazon couldn't ignore the demand for a managed Kubernetes offering, and in late 2017, Amazon added Elastic Container Service for Kubernetes ( EKS). Alternatively, users could run their own Kubernetes clusters on EC2. It enables companies to reap the benefits of containers without having to deal with the complexity and overhead that previously went with them.ĪWS has a fairly successful managed container orchestration service of its own -Amazon Elastic Container Service. Kubernetes, an open source container orchestrator, simplifies automation, deployment, scaling and operation of containerized applications. ![]()
