  Private image

  A private image is created from an ECS or an external image file and is visible only to its creator. Each private image contains an OS, preinstalled public applications, and the creator's private applications. Creating ECSs using a private image frees you from repeatedly configuring ECSs.

  Public image

  A public image is provided by the public cloud system. It contains a standard OS and preinstalled public applications, and is visible to all users. You can configure the application environment and required software based on your requirements.

  System disk image

  A system disk image contains an OS for running services and application software. It can be used to create system disks, and can also be directly used to create ECSs. Through system disk images, you can migrate your service running environment to the cloud.
