Summary
Integrating the virtual compute platform into ACI extends the policy model down and provides deep visibility into the virtualization layer. As discussed in this chapter, due to the open architecture of Cisco ACI, any hypervisor or container-based platform vendor—such as VMware, Microsoft, OpenStack, Kubernetes, or OpenShift—can be integrated into ACI.
In a single ACI fabric located at a single site or stretched between multiple sites using transit leaf, multi-pod, or remote leaf, individual VMM integration can be leveraged using the same policy model in any of the locations where the ACI fabric is stretched because a single control and data plane has been stretched between multiple data center locations. In a dual ACI fabric or multi-site environment, separate APIC clusters are deployed in each location; therefore, a separate VMM domain is created for each site.
