Alibaba Cloud Simple Application Server provides three types of images: application images, OS images, and custom images. When you create a simple application server, you can select an image based on your business requirements. This topic describes the image types that are supported by Simple Application Server. This topic also describes the image names and image versions of each image type.

Image types

The following table describes the application images, OS images, and custom images that are provided by Simple Application Server.
Type Description
Application images Application images contain applications, initialization data and runtime environments of the applications, and OSs. After you create a simple application server from an application image, you can use preset applications or customize application configurations based on your business requirements. Application images provide ready-to-use applications. This way, you do not need to upload or install applications.

For more information, see Build a WordPress blog.

OS images OS images contain only the OSs that are required to start servers. OS images do not contain application data or environment configurations. After you create a simple application server from an OS image, the server runs on an OS without installed applications. You can install applications on the server based on your business requirements.

For more information, see Deploy Apache based on a CentOS system image.

Custom images A custom image is created from a snapshot of a simple application server. You can use custom images to create multiple simple application servers that have the same configurations. You can also share custom images with Elastic Compute Service (ECS) and use the shared images to create ECS instances or replace the OSs of existing ECS instances.

For more information, see Overview of custom images.
