What it does

Plan and manage OpenStack resource quotas and utilization

Best for

Cloud operators right-sizing overcommit ratios and quota policies to prevent outages

Inputs
  • · host inventory
  • · workload profile
  • · growth forecast
Outputs
  • · allocation ratio recommendations
  • · quota templates
  • · utilization report
Requires
  • · Placement service
  • · Nova
  • · Cinder
  • · Neutron quotas
Preconditions

OpenStack cloud deployed; metrics available from hypervisors; nova/cinder services up

Failure modes

Overcommit ratio too high (contention), underestimated growth, quota conflicts between projects

Trust signals
  • · NASA SE Phase E framework cited
  • · CPU/RAM/disk ratio table with workload profiles
  • · Placement service commands documented
