I see that Microsoft are continuing to post more great Azure training into the Microsoft Virtual Academy. If you look here, you will find some great videos that can ultimately prepare you for 70-533 (Implementing Microsoft Azure Infrastructure Solutions).
There are several great things about this training – first it's pretty current. Azure changes literally weekly which means some of the printed material from other training outlets can be woefully out of date!. Second, it's free. And finally, being simple videos, it's easy to watch in your spare time (Ed: what is that?).
