Custom images

Custom images are created based on existing cloud desktops or snapshots. A custom image includes the operating system, configurations, and data of deployed services or applications. You can use custom images to quickly and easily create multiple copies of cloud desktops that have identical configurations. The following figure describes the process of creating a custom image:Custom image
As shown in the preceding figure, Alibaba Cloud provides two methods to create a custom image:
  • Create an image by using a cloud desktop

    When you use a cloud desktop to create a custom image, the resulting custom image contains the data of both the system disk and data disk of the original cloud desktop.

  • Create an image by using a snapshot

    You can use only snapshots of the system disk to create custom images. The resulting custom images contain only the data of the system disk of the original cloud desktop.

After you create a custom image, you can use the custom image to create a desktop template. Desktop templates allow you to create multiple identical cloud desktops with ease. For more information, see Create a desktop template.
