ACI

Cisco ACI is the industry-leading SDN solution that automates network management through intent-based policies and centralized control.

Cisco Application Centric Infrastructure (ACI) transforms data center operations by replacing manual CLI configurations with a centralized APIC controller. It uses a spine-leaf architecture to deliver 40/100GbE performance while enforcing consistent security policies across physical and virtual workloads. By decoupling the network fabric from hardware endpoints, ACI reduces provisioning times from weeks to minutes (a critical edge for high-scale environments like financial services or healthcare). It integrates directly with platforms like VMware vSphere and Kubernetes to ensure your connectivity remains seamless, automated, and secure.
