While I don't intend to "bump" an old thread, I'd like to add onto this with a new type of course offered by Alphabet(parent company of Google) and Its called QwickLabs. The way its different is that it teaches you stuff about AI, VM, Cloud etc but actually offers you a vps where u can start a "lab" and learn on the go on it. The labs are temporary and close down after usually an hour but that is enough to practise on them.

While qwicklabs is a paid project, you can easily find codes online that allow you to launch a lab for free.
