How to post a large file to Amazon Kindle?

Thank you, but I don't understand. All I know is how to build a good course. I don't know how to package it as an app. I don't know how to host online and I cannot believe Articulate 360 would require me to expose all my files to a download. Nor can I imagine that a Kindle user would be expected to download all those files and then sort through them to try and find the story.html file to execute. 

I am sorry, but this just doesn't make sense to me. Again, I am grateful for the response, but I just don't get it.

Is there someone I can hire to do this for me? Would I look for a developer? My company's IT guy is really savvy, but he was at a loss as to how to make this work. 

I spent 9 months building this course and now it seems like it is impossible to distribute securely.  

Again, thanks for your response, but I need really clear, step by step instructions. Or I need to hire someone that can do it for me. I am exhausted trying to figure this out. Can anyone help?
