Control Plane

Definitions

1. The part of a system responsible for configuration, orchestration, policy decisions, and coordination, as opposed to the data plane that handles live traffic or workload execution. Control planes are common in Kubernetes, networking, and managed platforms where one layer directs how another layer operates.

   In plain English: The management layer that decides how the rest of the system should run.

   Example: "The outage affected the control plane, so new deployments and scaling changes stalled even though existing traffic still flowed through the data plane."
