APIC (Application Policy Infrastructure Controller)

APIC (Application Policy Infrastructure Controller) is a centralized management system for Cisco's Application Centric Infrastructure (ACI). It serves as the brain of the network, coordinating and automating how network devices, policies, and applications work together. By providing a single interface, APIC simplifies configuring, monitoring, and managing complex data center networks, ensuring efficiency, security, and consistent policy enforcement. Essentially, it enables organizations to dynamically adjust their network infrastructure to meet application demands, improve performance, and reduce manual errors.
