OpenCart downloads a file by clicking on the "Download" button

I would like to understand whether it is possible to somehow implement a file on the page of our site when you click on the "Download" button.



For example, we upload books to the cloud, it is necessary that when you click on the "Download" button, the file is downloaded immediately.

Understand which cloud for such purposes it is better to upload files.
