You can dynamically scale OpenStack services in or out to adapt to a changing system load.


VMware Integrated OpenStack does not support scaling the following services in or out:

  • Gnocchi
  • Ingress
  • MariaDB
  • Memcached
  • Nova compute
  • RabbitMQ

Do not attempt to scale these services in or out using the web interface, command-line interface, or API.


  1. Log in to the Integrated OpenStack Manager web interface as the admin user.
  2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
  3. On the Services tab, find the desired OpenStack component and select Actions > Scale out.
  4. For each service in the component, enter the desired number of pods.
    Note: The maximum number of replicas for each service cannot be greater than the number of worker nodes.
  5. Click OK.


Service pods are created or terminated to reach the specified number.
