Orchestration coordinates application operations across distributed infrastructure. Kubernetes continuously works to keep an application in its declared healthy state despite the challenges of distributed architectures. section 2.3.5
A Kubernetes cluster separates a control plane, which manages cluster resources and scaling, from worker nodes, which run applications. Its standardized APIs also make orchestration extensible. section 2.3.5

Use the cluster diagram to see how control-plane services relate to the worker nodes running applications. section 2.3.5
At the platform level, an orchestrator such as Humanitec can automate infrastructure provisioning, resource allocation, configuration, and scaling. Developers can use self-service deployment without managing every underlying detail. section 10.5.3
