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)
