A company is transitioning its network operations to a more flexible and management-efficient architecture due to its rapidly evolving service demands. They want centralized control of network devices so administrators can push policies and configurations from a single controller instead of logging in to each device at its physical location. Which solution would best fit their needs?
Software-defined networking (SDN) abstracts the control plane from the data plane, placing control logic in a centralized SDN controller. Administrators use this controller to program the network and enforce policies across all switches and routers, eliminating the need to configure each device individually. Although SD-WAN also uses centralized orchestration, its primary goal is to optimize and manage traffic across multiple WAN links between sites. Zero Trust Architecture is a security framework focused on continuous verification and least-privilege access, and a traditional VPN only provides encrypted connectivity without centralized device management. Therefore, SDN best satisfies the requirement for centralized configuration of network devices.
