Elastic Kubernetes Service (EKS) is a managed service provided by AWS for deploying, scaling, and managing containerized applications using Kubernetes. Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
EKS makes it easy to run Kubernetes clusters on AWS by handling the underlying infrastructure for you. It simplifies the process of setting up and managing the control plane, which is responsible for managing the cluster's resources and scheduling workloads.
With EKS, you can take advantage of the scalability, flexibility, and resilience of Kubernetes to run your applications on AWS. The service provides features such as automatic scaling, load balancing, and integration with other AWS services.
Here's an example of how you can use EKS to deploy a Kubernetes application:
1import io.fabric8.kubernetes.client.DefaultKubernetesClient;
2import io.fabric8.kubernetes.client.KubernetesClient;
3import io.fabric8.kubernetes.client.dsl.NamespaceListVisitFromServerGetDeleteRecreateWaitApplicable;

5import io.fabric8.kubernetes.client.dsl.Resource;
6import io.fabric8.kubernetes.client.dsl.ServiceResource;
