Cloud, and really any vendor specific stuff, is tough to keep up with both in terms of learning and creating training materials. You’re better off getting it straight from amazon, google or other practitioners. See if you can find some smaller conferences in your area, and if you can spend training budget on that.

Obviously $200 isn’t much, but coursera might be a better bang for your buck than some other systems. Learning core skills will help you level up, while a lot of Udemy and similar content will just keep you on the same track you would have been on.
