Application focused

In the SDN architecture, the control and data planes are decoupled, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications.

The focus relies on the application rather than the network or servers.




Cisco Application Centric Infrastructure (ACI) is taking data centers to the next step in automation. Cisco’s software-defined networking (SDN) architecture, Cisco ACI enhances business agility, automates IT tasks, and accelerates data center application deployments. Its application-based policy model offers speed through automation, reducing errors and accelerating application deployment and IT processes from weeks to minutes.



As a result, enterprises and carriers gain unprecedented programmability, automation, and network control, enabling them to build highly scalable, flexible networks that readily adapt to changing business needs




Cisco ACI is a comprehensive software defined networking (SDN) solution that is provided on an agile, open, and highly secure architecture. Unlike other infrastructure solutions, it makes the application the focal point.


In Cisco ACI solution the network hardware is  equipped  with a new kind of intelligence. Administrators can create, customize, and duplicate network policies. Then they can instruct the infrastructure to follow these rules for specific applications. In effect, the intelligence is in the software within the infrastructure rather than an independent application.
