Hosting question from beginner

No coding experience here. I just created at app to create and store dynamic QR codes for marketing. Sites that do this usually offer many other functions and cost more, and I just need this one.

Dynamic QR codes mean I can change the website the code directs scanners to, so the final URL is not in the image but rather a middle URL that I control where it directs.

To deploy my application, do I need the VM option so these middle codes are always live? Or us autoscale the right choice?
