New to cloud

So I have a small background in Web development and I thought I'd use this for my undergraduate project in my final year but look more into cloud. I know a few areas for research. However, I was wondering, would comparing companies for the 'ideal' service/provider for migration be an ideal topic of research? Or could automation of any migration be a better choice?

If the latter, what areas would be even able to be automated?

Again, sorry if this is blatantly obvious... I'm new.

Thanks.
