Cisco ACI (Application Centric Infrastructure)

Optimizing the Data Center with Cisco ACI

Cisco Application Centric Infrastructure (ACI) is the industry-leading software-defined networking (SDN) solution for the data center, designed to automate and secure complex application workloads.

What is Cisco ACI?

Cisco ACI is a policy-driven architecture that transforms the data center into a highly agile, automated environment. In a traditional data center, networking is focused on IP addresses, VLANs, and physical ports, which can be rigid and difficult to manage as applications scale. ACI flips this model by focusing on the application itself. It uses a "Leaf-Spine" physical topology managed by a central controller known as the APIC. Administrators define "Endpoint Groups" based on what an application does, rather than where it is physically located. This allows for a completely abstracted network where policies follow the workload across physical servers, virtual machines, or containers, ensuring that security and performance remain constant even as apps move or scale.

What is Cisco ACI used for?

ACI is primarily used by large enterprises and service providers to accelerate the deployment of new applications and services. By automating the network configuration process, ACI reduces the time it takes to provision an application from weeks to minutes. It is also used as a foundational tool for Zero Trust security within the data center. Through micro-segmentation, ACI ensures that even if one part of a system is compromised, the threat cannot move laterally to other sensitive areas. Furthermore, CTOs leverage ACI for hybrid cloud integration, using it to create a single, consistent policy domain that spans on-premises data centers and public cloud environments like AWS or Azure, providing a "single pane of glass" for global infrastructure management.

Key Technical Capabilities

• Centralized Policy Controller (APIC): A single point of truth for managing all physical and virtual network assets.
• Zero-Trust Micro-segmentation: Isolating workloads at a granular level to prevent lateral threat movement.
• Multi-Cloud Extension: Extending consistent networking and security policies to public cloud providers.
• Open API Ecosystem: Integrating seamlessly with DevOps tools like Terraform and Ansible for Infrastructure as Code.
• Real-Time Telemetry: Gaining deep visibility into application health and network performance through the Nexus Dashboard.
