Cisco ACI is a software-defined networking (SDN) solution that enables enterprises to build a unified, policy-based network infrastructure that supports both virtualized and traditional workloads. The key to ACI’s success is its Application Policy Infrastructure Controller (APIC), a centralized controller that manages the entire ACI fabric.
ACI’s centralized policy control and management is made possible by its leaf-spine architecture. The leaf nodes are the edge switches that connect to endpoints, such as servers, storage, and hosts. The spine nodes are the core switches that connect the leaf nodes to each other.
The leaf-spine architecture provides a high-performance, scalable, and highly available network that can be easily managed using the APIC.
ACI also includes a number of features that make it an attractive SDN solution for enterprises. These features include:
Multi-tenancy: ACI supports multiple tenants, each with their own virtual network. This enables enterprises to segment their network to better meet their security and performance needs.
Security: ACI includes a number of security features, such as role-based access control, that helps enterprises secure their network.
Automation: ACI’s policy-based approach to networking enables enterprises to automate many of the tasks associated with configuring and managing a network. This includes the ability to automatically provision new services and applications.
Cisco ACI is a powerful SDN solution that enables enterprises to build a unified, policy-based network infrastructure that supports both virtualized and traditional workloads. The key to ACI’s success is its Application Policy Infrastructure Controller (APIC), a centralized controller that manages the entire ACI fabric. The APIC provides a single point of control and management for the ACI fabric and simplifies the creation and enforcement of network policies. It also automates many of the tasks associated with configuring and managing a complex network.
