What is the control plane?

The control plane is the brain of a distributed system, directing how the rest of the system behaves and orchestrating the processing of data to accomplish specific tasks or goals in various areas such as cloud computing, networking, databases, analytics, and software as a service architecture. The control plane plays a vital role in enforcing security policies and mechanisms, implementing access controls, encrypting data transmissions, and ensuring compliance with security standards. It also abstracts the underlying hardware in an SDN architecture, allowing for more flexible and programmable network management. The evolution of cloud technology has seen the integration of software-defined networking principles into the control plane, enabling efficient and agile responses to changing network conditions.
