Cisco Application Centric Infrastructure

Cisco Application Centric Infrastructure is a software-defined networking solution that automates data center networking policy, provisioning, and visibility with a declarative model.

What is Cisco Application Centric Infrastructure?

Cisco ACI replaces much of the manual interface and VLAN labor in traditional data centers with a policy-driven, declarative networking model. It is designed for enterprises that want consistent workload connectivity, faster change deployment, and better visibility across physical and virtual infrastructure. Buyers should plan for networking expertise, change management, and integration work, especially when merging ACI into brownfield environments.
