Kubernetes is an open-source platform that automates the deployment, scaling, and management of containerised applications. It orchestrates clusters of virtual machines, scheduling containers based on their resource requirements and availability. Kubernetes handles self-healing by restarting failed containers, replacing them, and terminating those that fail health checks. It automates rollouts and rollbacks, ensuring smooth deployment of application changes while monitoring application health. Kubernetes also manages service discovery and load balancing, exposing containers via DNS names or IP addresses and balancing network traffic. It orchestrates storage by automatically mounting various storage systems, whether local, cloud-based, or networked.
