Cisco’s ACI (Application Centric Infrastructure) is a data center solution that enables customers to increase agility, improve efficiency, and reduce costs. The ACI fabric is designed to enable applications to be deployed quickly and easily, while still providing the security and performance required by today’s businesses. The ACI fabric is comprised of a number of different components, including the APIC (Application Policy Infrastructure Controller), the leaf and spine switches, and the application-specific integrated circuits (ASICs).
The leaf and spine switches are the workhorses of the ACI fabric and are responsible for forwarding traffic between the endpoints. The leaf and spine switches are connected to each other using a high-speed interconnect, which allows them to share state information and maintain a consistent view of the ACI fabric.
The ASICs are responsible for forwarding traffic within the ACI fabric. The ASICs are designed to offload the forwarding decision from the CPU to the hardware, which enables the leaf and spine switches to forward traffic more efficiently.
The ACI fabric is designed to be highly scalable and can support a large number of endpoints. The ACI fabric can also be easily expanded by adding additional leaf and spine switches.
The ACI fabric is also designed to be highly available. The leaf and spine switches are connected to each other using multiple links, which provides redundancy and eliminates single points of failure. In addition, the APIC can be deployed in a highly available configuration.
The ACI fabric is designed to be secure. The leaf and spine switches support role-based access control, which allows the administrator to control which users have access to which resources. In addition, the ACI fabric supports encrypted communication between the APIC and the leaf and spine switches.
The ACI fabric supports a number of different applications, including virtualized applications, bare-metal applications, and containerized applications. The ACI fabric is also designed to work with a variety of different types of networking hardware, including traditional routers and switches, as well as newer technologies such as software-defined networking (SDN) and network functions virtualization (NFV).
The ACI fabric is a flexible and powerful data center solution that can be used to deploy a variety of applications. The ACI fabric is easy to manage and can be quickly and easily expanded to support a growing number of endpoints. The ACI fabric is also secure and scalable, making it an ideal solution for today’s businesses.
