Creating a Private Image

IMS provides full-lifecycle management for private images, including creating, replicating, sharing, and exporting private images. You can choose a proper method to migrate services to the cloud or on the cloud with the cooperation of other services, such as ECS and OBS.

Private images include system disk images, data disk images, and full-ECS images. Private images are created from ECSs or external image files. A private image is available only to the user who created it and the user with whom it has been shared.
