A cloud computer template is a collection of necessary resources for quickly creating cloud computers. You can use a system template or create a custom template based on your business requirements. You can also back up your cloud computer configurations as cloud computer templates and use the templates to create cloud computers with the same configurations. This topic describes how to create, modify, and delete a custom cloud computer template.
Prerequisites
The image that you want to use to create a cloud computer template is available. You can select a system image, a custom image, or a shared image.
A custom image is available if you want to use a custom image to create the cloud computer template. For more information, see Create an image.
A shared image is available if you want to use a shared image to create the cloud computer template. You can copy or share an image to the region in which you want to create the template in advance. For more information, see Copy an image or Share or unshare an image.
Background information
Cloud computer templates are classified into system templates and custom templates. A system template is a default template provided by Alibaba Cloud, and a custom template is a template that you manually create. A template contains all required configurations for creating a cloud computer, such as an image, the vCPU and memory specifications, GPU memory, system disk, and data disk.
