With VMware Integrated OpenStack, you can implement OpenStack services on your existing VMware vSphere implementation.You can deploy VMware Integrated OpenStack through the Integrated OpenStack Manager vApp in vCenter. The Integrated OpenStack Manager provides a workflow that guides you through and completes the VMware Integrated OpenStack deployment process. With Integrated OpenStack Manager, you can specify your management and compute clusters, configure networking, and add resources. Post-deployment, you can use Integrated OpenStack Manager to add components or otherwise modify the configuration of your VMware Integrated OpenStack cloud infrastructure. VMware Integrated OpenStack 2.0 is based on the Kilo release of OpenStack. (Version 1.0 was based on the Icehouse release)
VMware Integrated OpenStack Architecture:
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. Integrated OpenStack Manager creates one Compute driver instance in the management cluster for each compute cluster. The management cluster contains the VMs that comprise your OpenStack cloud deployment. It also contains the memory cache (memcache), message queue (RabbitMQ), load balancing, DHCP, and database services. VMware Integrated OpenStack deployments can use NSX-V for the Networking component. You will require an additional cluster for the NSX-V Edge nodes.
