High Availability (HA) controller +n compute deployment
This topology is for larger test and production environments that require highly available (HA) cloud controller nodes.
The HA controller + n compute topology supports multiple cloud controller nodes that are configured to be highly available and load balanced. The IBM® Cloud Manager with OpenStack HA controller nodes manage the availability of the IBM OpenStack controller services, excluding the OpenStack compute node services. The OpenStack compute node services are provided by the OpenStack compute nodes, but are not configured to be highly available. This topology supports the following OpenStack supported compute hypervisors:
- x86 KVM
- PowerKVM (Note: The controller nodes must run on x86-64)
