Put "Autoscaling for Compute"[1] and "Autoscaling for Instances" into a single doc called "Autoscaling the OpenStack Cloud." [1] https://access.redhat.com/documentation/en/red-hat-enterprise-linux-openstack-platform/7/auto-scaling-for-compute/chapter-1-configure-auto-scaling-for-compute
I can't find any reference to an "Autoscaling for Instances" article or document in our docs set, so perhaps that content never came into being. Closing this bug.
