Changes the configurations of a cloud desktop, including the vCPUs, memory size, and disk size.

Description

You can call this operation to change the configurations, such as the desktop type and disk size, of a cloud desktop.

  • Before you call this operation, take note of the cloud desktop types and the disk sizes for each type of cloud desktop that Elastic Desktop Service (EDS) provides. For more information, see Cloud desktop types.
  • When you change the configurations of a cloud desktop, you can change the desktop type or the size of the system disk or data disk. You must configure at least one of the following parameters: DesktopType, RootDiskSizeGib, and UserDiskSizeGib. Take note of the following items:
    • Each desktop type contains different desktop specifications, such as vCPUs, memory size, and GPUs. You cannot change only one of these specifications. If you want to change the desktop specifications, you must change the desktop type.
    • You cannot change a cloud desktop from the General Office type to a non-General Office type, or from a non-General Office type to the General Office type. You cannot change a cloud desktop from the Graphics type to a non-Graphics type, or from a non-Graphics type to the Graphics type.
    • You can only increase the sizes of system and data disks.
    • If the cloud desktop uses the subscription billing method, the price difference is calculated based on the price before and after the change. You can receive a refund, or must pay for the price difference.
    • If you want to change the type of cloud desktop for multiple times, we recommend that you wait at least 5 minutes before you change the desktop type if you want to change it again.
    • The cloud desktop for which you want to change configurations must be in the Stopped state.
  • The changes do not affect your personal data on the cloud desktop.
