Kubernetes, commonly abbreviated as K8s, is an open-source container orchestration platform originally developed by Google and now maintained by the Cloud Native Computing Foundation (CNCF). It automates the deployment, scaling, and management of containerized applications across clusters of machines, eliminating much of the manual effort traditionally required to run distributed systems at scale.
At its core, Kubernetes organizes containers into logical units called pods, which are scheduled across a cluster of nodes. It provides built-in mechanisms for service discovery, load balancing, automated rollouts and rollbacks, self-healing, and secret management. These capabilities allow development teams to focus on writing application code rather than managing infrastructure.
Kubernetes has become the de facto standard for container orchestration in modern cloud-native development. Major cloud providers including AWS (EKS), Google Cloud (GKE), and Microsoft Azure (AKS) offer managed Kubernetes services, making it accessible to organizations of all sizes. Its rich ecosystem of tools, extensions, and a vibrant open-source community ensure that Kubernetes continues to evolve alongside the demands of contemporary software delivery.
