What is the primary function of cloud-based AP architecture?

In cloud-based access point (AP) architecture, the primary function involves moving the controller function to the cloud. This architecture allows for centralized management of multiple access points without the need for a dedicated on-premises controller. By leveraging cloud resources, network administrators can efficiently manage configurations, updates, and monitoring from a centralized interface accessible from anywhere with an internet connection.

This cloud-based approach enhances scalability, as adding new access points to the network can be done quickly without extensive local setup. Additionally, it provides the advantage of real-time analytics and the ability to implement network policies consistently across all locations.

In contrast to the other options, using the cloud solely for data plane management does not capture the holistic management capabilities that cloud controllers provide. Similarly, while some traffic may be forwarded to the cloud for monitoring or processing, it is not accurate to say that all traffic is directed this way, as local data forwarding often continues for performance reasons. Finally, while access points may have some level of independent operation, they are designed to be centrally managed, distinguishing the cloud-based model from purely autonomous AP setups.
