Overview

A private image contains an OS or service data, preinstalled public applications, and a user's personal applications. Private images are only available to the users who created them.

IMS provides multiple methods for creating private images.

Creating a private image from a cloud server or a backup	If you already have an ECS on Huawei Cloud and configured it based on your service requirements (for example, by installing software or setting up an application environment), you can use this ECS to create a private image. A private image can be a system disk image, data disk image, or full-ECS image. System disk image: contains an OS and application software from the system disk. Data disk image: contains service data from data disks. Full-ECS image: contains data of an entire ECS, that is, the OS and application software from the system disk and service data from data disks.

Creating a private image from an image file	You can import an image file from your local PC or other cloud platforms to Huawei Cloud IMS and register it as a private image. Then, you can use the image to create new ECSs or data disks, or change the OS for existing ECSs. This way, your services can be migrated to the cloud or in the cloud.	Overview
