Linux academy is the best online training platform on the market for AWS, full stop.
I have achieved my CSAPro and Linux Academy has been essential for me to prepare for the exam. The breadth and depth of the course is adequate, the instructor does an excellent job by being brief and clear while maintaining adequate detail (the tone is also good) and the labs were handy, specially when one doesn't use a certain AWS service and needs a use case to force it to try it out.
ps: The employee that continuously shuts down production servers can indeed be stopped by a policy, but every-time I saw that question I couldn't help thinking it should be fired too. :)
