What is Container Orchestration?

The automated management of containerized applications including deployment, scaling, networking, and health monitoring across clusters.

Container orchestration handles the operational complexity of running containers at scale. It automates container placement across nodes, scaling up/down based on demand, load balancing between container instances, rolling updates, health checking, and automatic restart of failed containers. Kubernetes is the dominant orchestration platform, but alternatives include Docker Swarm, HashiCorp Nomad, and managed services like AWS ECS. Orchestration transforms containers from a developer convenience into a production-grade deployment platform, enabling organizations to run hundreds or thousands of containers reliably.
