Multi-region topology
This topology is for larger test or production environments and can include multiple hypervisor environments.
- KVM/QEMU
- KVM for z Systems®
- PowerKVM
- PowerVC
- z/VM®
- Hyper-V
- VMware
When you create this topology deployment, you need one system for the deployment server along with a single controller node for each region. You deploy a separate cloud for each region. Each region must have its own controller. You configure the multi-region topology to share the same Keystone and potentially IBM Cloud Manager - Dashboard.
If the KVM/QEMU, KVM for z Systems,PowerKVM, Hyper-V, or z/VM compute hypervisor is used, then one or more systems are also required to provide the IBM Cloud Manager with OpenStack compute nodes for the topology.
If you want to deploy a topology to manage to PowerVC, PowerVC driver services should run on the same node as the single controller node. It also requires an existing IBM Power® Virtualization Center to be available.
If you want to deploy a topology to manage to VMware, VMware driver services can run on the same node as the single controller node or on a separate node. It also requires an existing VMware vCenter to be available. If you plan to manage multiple vCenter servers, create a region for each vCenter; template images cannot be shared across multiple vCenter servers.
