When using CLIs to manage stacks, you only need to edit a template file. Then, you can use it directly. When you choose to upload a template to the RTS console to create stacks, you need to prepare a template file and compress the template file based on the required format before using the template. This method is applicable to a wider range. Both single and nested templates can be uploaded. When you choose to edit a template online, you do not have to compress the template file. The online editing mode applies to the single-template scenario.
