Licensing on public clouds
Software that is installed on computers that run on public clouds is licensed according to the BYOSL policy. To ensure that license metric utilization is properly calculated for such software, computers must be identified as running on public clouds.

To ensure that proper counting rules are applied by License Metric Tool, identify the computers that run on pre-approved public clouds and specify the types of clouds on which they run. For more information, see: Identifying computers as running on public cloud.

Other public clouds
If you want to use License Metric Tool and BYOSL policy on a public cloud other than the pre-approved public clouds, write an e-mail to talk2sam@us.ibm.com to obtain an approval. In your request for approval, specify the exact type of the public cloud, the list of products you want to use, the approximate number of computers to manage with such a public cloud, the IBM Customer Number (ICN) and your country or region.
After you obtain a written approval from IBM for the specific use case, configure License Metric Tool accordingly to ensure correct license usage calculation and stating approval details. For more information, see: Identifying computers as running on public cloud.
Operating systems supported on public clouds
- Windows
- Linux
- AIX
Limitations
License Metric Tool does not support public cloud VMs that are identified by duplicated serial numbers. The serial number is usually the UUID of the virtual machine that is assigned by the VM manager of the particular public cloud.
