Cisco Application Centric Infrastructure (ACI) is a software-defined networking (SDN) solution for data centers that offers centralized application policy management and network automation. The Cisco ACI fabric consists of APIC controllers and leaf/spine switches. The APIC provides a single point of control and management for the ACI fabric. The leaf and spine switches are responsible for forwarding traffic to and from the endpoints.
Once the model is deployed, the network devices will automatically configure themselves to implement the desired application policy. This eliminates the need for manual configuration of individual devices, which can be error-prone and time-consuming.
Cisco ACI also offers network automation features such as auto-configuration of new devices, automatic detection of faults, and automatic recovery from failures. These features further simplify the management of large and complex data center networks.
The Cisco ACI solution offers many benefits for data center operators, including reduced operational expenses, improved application performance, and increased agility.
