Using SharePoint Online for hosting public web files

Thank you! Performance is key, people want the same experience every time. We aren't looking to host web pages, just documents but seeing how they respond on our WordPress pages we were thinking this may not be a viable option. One of the reasons I was hoping this would work on SPO is the fact we could keep all contents in one place whether it is internal or external, minimal effort on our users for document management for web. I will take a look at Azure, thank you for the suggestion.
