License Types

BYOL

What Is BYOL?

Bring your own license (BYOL) allows you to use your existing OS license. In such a case, you do not need to apply for a license again.

How to Use BYOL?

If you select the BYOL license type, you are required to manage licenses by yourself. If you have obtained an OS license, you do not need to apply for a license.

The OSs supporting BYOL are as follows:
  • Windows

Application Scenarios

The system does not support dynamic license type changing. ECSs support BYOL in the following scenarios:

  • Creating an ECS

    After creating an ECS, you cannot change its license type. If the license type must be changed, reinstall or change the ECS OS.

  • Reinstalling an ECS OS

    When reinstalling an ECS OS, you can set the license type for the ECS.

  • Changing an ECS OS

    When changing an ECS OS, you can set the license type for the ECS.

  • Attaching a system disk

    The license type of a system disk is determined by the ECS license type after the ECS is created, the ECS OS is reinstalled, or the ECS OS is changed. If the system disk is detached and then attached to a new ECS or the original ECS, ensure that the ECS license type is the same as the system disk license type.
