The Cloud Controller Manager (CCM) is a Kubernetes control plane component that embeds cloud-specific control logic. It allows Kubernetes to integrate with underlying cloud provider APIs and services.

> It's optional - Kubernetes can run without it (on-premises or with manual configuration)

> It's a control plane component - Part of the cluster's management layer, not the data plane

> It integrates with cloud infrastructure - Manages cloud-specific resources like load balancers, storage, and networking
