An Amazon Elastic Kubernetes Service (EKS) cluster is a managed Kubernetes environment that runs in the AWS cloud. It enables users to quickly deploy, scale and manage containerized applications using the same Kubernetes resources as on-premises deployments. EKS clusters are highly available, secure and scalable, offering users greater control over their containerized workloads without the need for complex configuration or setup. The service also integrates with other AWS services such as IAM, VPC and CloudWatch for seamless management of clusters and workloads. With EKS, organizations can benefit from improved resource efficiency, improved security posture and reduced time to market for new application features.
