The VMware Integrated OpenStack architecture connects vSphere resources to the OpenStack Compute, Networking, Block Storage, Image Service, Identity Service, and Orchestration components.
VMware Integrated OpenStack is implemented as compute and management clusters in your vSphere environment.
The compute cluster handles all tenant workloads. Your VMware Integrated OpenStack deployment can have multiple compute clusters. For each compute cluster, one compute driver instance is created in the management cluster.
The management cluster contains the VMs that comprise your OpenStack cloud deployment. It also contains the load balancing, DHCP, and database services.
VMware Integrated OpenStack deployments can use NSX for the Networking component. You will require an additional cluster for the NSX Edge nodes.
