What is Kubernetes?

Kubernetes is an open-source container orchestration platform that automates deploying, scaling, networking and healing containerized applications across a cluster of machines.

Definition: Kubernetes is an open-source container orchestration platform that automates deploying, scaling, networking and healing containerized applications across a cluster of machines.

Key concepts

A cluster has a control plane and worker nodes. Pods are the smallest unit and hold one or more containers. Deployments declare how many replicas should run, Services give pods a stable network address, and Ingress or gateways route outside traffic. You describe the desired state in YAML and Kubernetes continuously works to match it.

Why teams use it

Self-healing restarts, rolling updates, autoscaling and a consistent way to run microservices across clouds. Managed offerings such as EKS, AKS and GKE handle the control plane.

Kubernetes for AI workloads

Kubernetes schedules GPU nodes for training and model serving, and is a common base for self-hosted open-weight models.

When it is overkill

For a few services, managed container or serverless platforms often cost less to run and operate. The guide on Kubernetes vs ECS compares options on AWS.
