This topic describes several methods of creating an ECS instance, from basic creation operations to advanced customization operations.

You can create an ECS instance and choose configurations by following the instructions prompted by the wizard on the buy page. For more information, see Create an instance by using the provided wizard.
Note If you require custom configurations such as a specific operating system or application, you can create a custom image and then select that image during the creation of an instance to improve configuration efficiency. For more information, see Create an instance by using a custom image.

If you need a new instance to have the same configuration as the current instance, you can create an instance of the same configuration. For more information, see Purchase an ECS instance of the same configuration.

You can also create a launch template in advance, and then use it to create an instance in one click. For more information, see Create an instance by using a launch template. For more information about launch templates, see Launch templates.
