Creating an Image

Scenarios

You can use an existing ECS to create a system disk image, data disk image, and full-ECS image.

  • System disk image: contains an OS and application software for running services. You can use a system disk image to create ECSs and migrate your services to the cloud.
  • Data disk image: contains only service data. You can create a data disk image from an ECS data disk. You can also use a data disk image to create EVS disks and migrate your service data to the cloud.
  • Full-ECS image: contains all the data of an ECS, including the data on the data disks attached to the ECS. A full-ECS image can be used to rapidly create ECSs with service data.
  • ISO image: is created from an external ISO image file. It is a special image that can only be used to create temporary ECSs.

If you plan to use a private image to change the OS, ensure that the private image is available. For instructions about how to create a private image, see Image Management Service User Guide.
