Kubernetes is an open-source container orchestration tool developed by Google and is also known as K8s. It is used in managing the complete lifecycle of containerized applications. Kubernetes provides high availability, scalability, and predictability to the containerized application. It automates the deployment, management, and scaling of containerized applications. Kubernetes also supports automated rollout and rollbacks, service discovery, storage orchestration, scaling, batch execution, and more. Kubernetes provides the cluster where containerized applications can be deployed. Kubernetes is not the only container orchestration tool, but various “Kubernetes Alternatives” are available in the market.
Before we talk about the “Alternatives to Kubernetes,” let’s explore the key components of Kubernetes. The Kubernetes cluster consists of at least one worker node where containerized applications are deployed and one master node or control plane which manages the worker nodes. The Control plane or master node consists of Kube-API server, etcd, Kube-scheduler, and Kube-controller-manager, whereas the worker node consists of Kubelet, Kube-Proxy, and Container Runtime.
