4 Best Practices to Keep in Mind WhenImplementingAmazon EKS

Amazon Elastic Kubernetes Service (EKS)is a managed Kubernetes container service that makes it easy to run and scale Kubernetes applications in the AWS cloud and on-premises.It ensures a more secure Kubernetes environment and supports AWS Virtual Private Cloud (VPC) for pod networking. Moreover, unlike many other cloud providers,Amazon EKS is compatible with many Kubernetes applications.

However, for many organizations, AWS EKS implementation can be a challenge. Here are some best practices to help you reduce the overwhelm and successfully implement Amazon EKS.

Best Practice #1: Set Up Two Subnets in AWS VPC

With Amazon EKS, you get a scalable and highly-available Kubernetes control plane running across three AWS Availability Zones (AZs) and an integrated console for Kubernetes clusters.The service Amazon EKS manages the availability and scalability ofcontrol plane nodes and automatically detects and replaces unhealthy nodes.

To create a cluster of Amazon EKS nodes, you should set up two subnets in your AWS VPC, one for each AZ. The VPC isolates your Kubernetes clusters from other customers’ clusters.Since compute resources are not shared among customers, you get high isolation to build secure and reliable applications.

Make sure your worker nodes use the private subnets and Kubernetes uses the public subnets. If required, you can use the public subnets as load balancers. Make certain that each worker on your cluster has a valid Identity and Access Management(IAM) role assigned because the EKS cluster requires the EKS-role-ARN IAM role to function properly.

Best Practice #2: Understand How Amazon EKS Functions Before Launching a Containerized Application

With Amazon EKS, you can setup and launch containers in just a few minutes. However, it’s good to first get a solid understanding of how it functions before starting your first Kubernetes cluster and launching your first containerized application.

Fortunately, with AmazonEKS, it’s easy to start, run, and scale Kubernetes clusters and applications. Thus, you will have more confidence when deploying your containerized applications with Amazon EKS.

Best Practice #3: Select a Suitable Cluster Name

Before starting, select a cluster name for the AWS EKS environment you will be using. The name must correspond with the name of the VPC. If you provide the cluster with the same name each time, you can avoid instances that overlap in the cluster.

Also, when putting together an EKS cluster, use the appropriate EC2 Auto Scaling Group. This will automatically create the cluster’s data nodes and the script for cloud formation will get executedin the background.

Best Practice #4: Use Available Help Resources

AWS provides numerous freeresources to help you get the most out of Amazon EKS, such as step-by-step guides, blogs, videos, and roadmaps.You will also get sample scripts and templates which you can use for successfully installing AWS EKS. Several free tools and plugins are also available for Kubernetes.

If you require further assistance during the installation process, contact an AWS Certified Engineer or an AWS Consulting Partner like Axcess.

Contact Axcess to Get Started with Amazon EKS

With Amazon EKS, you can run your containerized applications on Amazon Elastic Compute Cloud (Amazon EC2) and AWS Fargate, while taking advantage of world-class AWS networking and security services. Do keep in mind that the nature and scope of your Kubernetes application should guide the selection of the appropriate EKS implementation. In this way, your applications will enjoy greater levels of safety and productivity.
