What it is
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications across clusters of servers.
How it actually works
Kubernetes (often shortened to 'K8s' because of the 8 letters between K and s) emerged from Google's Borg system and was open-sourced in 2014. It has become the de facto standard for running containers in production at scale.
What K8s does: (1) scheduling — places containers onto servers based on resource needs, (2) self-healing — restarts crashed containers, replaces failed servers, (3) scaling — adds or removes container replicas based on load, (4) service discovery and load balancing — handles networking between services, (5) declarative configuration — you describe desired state, K8s reconciles current state to match.
Managed K8s offerings (2026): AWS EKS, GCP GKE, Azure AKS, DigitalOcean Kubernetes, Linode Kubernetes. Managed offerings handle the control plane (the K8s 'brain') so you only manage your worker nodes and apps.
When you need Kubernetes: running multiple services that need to scale independently, doing zero-downtime deployments, running stateless workloads at scale, needing portability across clouds. When you don't: simple one-service apps (Vercel / Cloud Run / ECS Fargate is simpler), small teams (K8s has a steep operational learning curve), early-stage products (you're optimizing prematurely).
