The solution's most valuable feature is its programmability and the automation you can do for large changes. It's not that automation wasn't available on any of the other Cisco platforms, like Cisco NX-OS, but not many people did it, Network Automation was just buzz word, but with MSO/NDO this automation becomes real for DC networking Stack. Cisco ACI is built on data application-centric infrastructure with automation and Cisco is bring more automation be working with partners like Nutanix etc We have not implemented Cisco ACI with APIC and spine and leaf in the application centric mode but in network centric mode be use another Cisco platform for micro-segmentation very successfully in protecting out internal environment. Even though it was a painful journey for us, right from day one, we went for a Cisco multi-site implementation with Cisco's MSO (Multi-Site Orchestrator), which is today called NDO. We configured and deployed Cisco ACI through an NDO. The way you can expand the platform within the data center allows you to have a top-of-the-row design instead of centralizing everything in one frame and one central network rack. You can have leaf switches in the cabinet where they are needed most. You can have a top-of-the-row design or within-a-row design instead of a centralized design. That architecture allows you to have spines in a central place, but leaves can be distributed wherever you need them.
