Cisco is a software-defined networking (SDN) solution designed for data centers. It shifts network management from a traditional hop-by-hop configuration to a centralized, policy-based model where the needs of the application define how the network behaves. Core Components
The "brains" of the operation. It is a centralized software controller that manages automation, policy enforcement, and health monitoring. Cisco ACI
Instead of configuring VLANs or ACLs on individual switches, you define "policies" in the APIC that automatically propagate across the entire fabric. Key Concepts & Terminology ensuring high performance and low latency.
The physical fabric uses Cisco Nexus 9000 Series switches in a topology where every leaf switch connects to every spine switch, ensuring high performance and low latency. Cisco ACI
