Kubernetes on AWS: a managed EKS cluster serving a load-balanced web app, built and torn down cleanly.
eksctl provisions the EKS control plane and a managed worker node. Kubernetes manifests deploy NGINX with three replicas, and a LoadBalancer service puts it behind an AWS load balancer. I validated the pods, the service and the live page in a browser, then deleted the cluster so nothing kept billing.
For a small business, this is the step from "it runs on one server" to an app that can scale and recover, without paying for idle infrastructure. Code is on my GitHub: github.com/nujabesploo/aws-eks-production-platform
