VMware Telco Cloud Automation sends out an alert when the licenses threshold crosses 90%. However, TCA remains functional and no service is impacted.

The TCA supports following two types of licences:
  1. CPU or Socket based License

  2. CPU Core based License (Added in TCA 3.0)

VNF resource consumption:

When designing the VNF catalog, it is mandatory to specify the virtual compute property at each VDU level in the TOSCA descriptor.

The TCA can use the information available in the descriptor to compute the overall vCPUs allocated to a particular VNF instance.

CaaS(Kubernetes VIM Types) consumption:

For CaaS, the calculation differs based on license type applied on TCA:

  • CPU or Socket based License: You need to define the resource limits in the Helm Chart definitions for each container in a CNF. The same resource limits are used for consumption calculation.

  • CPU Core based License : Licensing mechanism in TCA allows to count all K8s workload clusters resources and use them for consumption calculation.

CPU license usage is calculated based on the number of managed vCPUs per VIM. The transformation factor used for calculating CPU license usage is:

  1. For CPU or Socket license transformation factor is 12 vCPUs = 1 CPU Package License

  2. For CPU Core license transformation factor is 1 vCPUs = 1 Physical Core = 1 License Unit


To increase the license capacity, obtain a license key with new license capacity, and apply that on TCA, visit the VMware customer care portal or contact the license team.

To view the details about the number of available and used licenses, perform the following steps:


  1. Log in to the VMware Telco Cloud Automation web interface.
  2. From the left navigation pane, go to Administration > Licensing.


The Licensing page displays the CPUs available and utilized per VIM.
