Cisco Aci Fundamentals

Cisco Application Centric Infrastructure (ACI) is a unique architecture that enables IT to increase agility while reducing TCO. ACI is built on industry standards and proven Cisco technologies, making it easy to use and scalable. ACI provides a centralized policy model that automates and accelerates application deployment while reducing operational complexity.

Cisco ACI is built on three key concepts:

1. Application-centric: All applications are treated as first-class citizens, with each application getting its own dedicated network resources. This approach enables IT to be more agile in responding to business needs.

2. Centralized policy: ACI uses a centralized policy model to automate the provisioning and management of network resources. This reduces operational complexity and enables faster application deployment.

3. Scalable: ACI is designed to be highly scalable, with a multi-tenant architecture that supports up to 8,000 tenants.

Cisco ACI consists of the following key components:

1. Application Policy Infrastructure Controller (APIC): The APIC is the centralized policy engine that provides a single point of control for the ACI fabric. The APIC uses an application-focused policy model to automate the provisioning and management of network resources.

2. Cisco Nexus 9000 Series Switches: The Cisco Nexus 9000 Series Switches form the foundation of the ACI fabric. These switches are purpose-built for ACI and offer high performance, scalability, and flexibility.

3. Cisco Application Virtual Networking (AVN): AVN is a software-defined networking (SDN) solution that provides network virtualization and orchestration for the ACI fabric. AVN enables the creation of virtual networks that are isolated from the underlying hardware.

4. Cisco ACI Multi-Site: ACI Multi-Site is a solution that enables the extension of the ACI fabric across multiple physical locations. ACI Multi-Site provides a consistent policy model and centralized management across multiple ACI fabrics.

5. Cisco Nexus 1000V Series Switches: The Cisco Nexus 1000V Series Switches are virtual switches that run on top of a hypervisor. The Nexus 1000V Series provides network visibility and control within the ACI fabric.

The Cisco Nexus 9000 Series Switches are the foundation of the ACI fabric and offer high performance, scalability, and flexibility.
