Containerization packages an application and its dependencies into an image that a runtime can execute. Orchestration coordinates many running containers across infrastructure, including placement, rollout, scaling, service discovery, and recovery.
Container Orchestration Tools: How to Choose a Deployment Platform

Container orchestration is the control layer that schedules workloads, replaces failed instances, manages configuration, exposes services, and coordinates releases across a cluster or managed platform. Choosing a tool is less about the longest feature list and more about the control your workloads require and the operational responsibility your team can sustain.
Start with the deployment model. A managed Kubernetes service reduces control-plane work but still leaves significant platform responsibility. A higher-level container service can remove more operations at the cost of portability or control. A self-managed orchestrator offers flexibility, but your team owns upgrades, reliability, security, and capacity.
Kubernetes is an orchestration system for managing containerized workloads and services; it is not the tool that builds the application image. Its core workload controllers manage Pods and provide rollout, scaling, and recovery behavior. Use the Kubernetes concepts documentation and workload-management documentation as the source of record for Kubernetes capabilities.
Containerization itself acts like a standardized shipping box for software, wrapping the code and all its necessary files into a single lightweight package (like a Docker container) so it runs reliably on any computer. Orchestration is the automated traffic control system (like Kubernetes) that manages these boxes — scheduling where they go, restarting them if they crash, and scaling the number of boxes up or down based on customer demand.
