You can scale your network function in or out by aspect or instantiation level.

Prerequisites

Note:
  • For this release, you cannot define a network function's scale aspects using the Network Function Designer. Instead, you can manually add the scale aspects to your descriptor YAML file as a part of the Policies section.
  • Scale aspects and minimum and maximum values cannot be identified for network functions that are imported from a partner system. For these network functions, you must enter the valid values manually.
  • The scale to level feature is not supported for network functions that are imported from a partner system.
  • You can set the instantiation scale when instantiating a Virtual Network Function (VNF).

Verify that the network function descriptor for the instantiated network function includes scaling aspects. Network functions without scaling aspects cannot be scaled.

Procedure

  1. Log in to the VMware Telco Cloud Automation web interface.
  2. Select Network Functions > Inventory.
  3. To scale a network function by aspect, perform the following steps:
    1. Click the Options (three dots) icon for the desired network function and select Scale.
    2. In the Scale tab, select the aspect to scale.
    3. Drag the scroll bar to select the number of steps to scale to be performed. The default number of steps is 1.
    4. Click Next.
    5. In the Inputs tab, enter the input variables required for starting and ending the scale. These credentials are required for running a workflow.
    6. Click Next.
    7. In the Review tab, review your configuration and click Finish.
  4. To scale a network function by instantiation level, perform the following steps:
    1. Click the Options (three dots) icon for the desired network function and select Scale To Level.
    2. Select whether to scale the entire network function or only certain aspects.
    3. Select the desired scale level and click Next.
    4. In the Inputs tab, enter the input variables required for starting and ending the scale to level. Provide any required inputs appropriately.
    5. Click Next.
    6. Review the configuration and click Finish.
