Director has given me a budget for a training session. What should I choose?

He offered this course, which looks pretty neat, but I'm just not super excited about cyber security, is this the wrong attitude?

I was thinking about maybe taking an AWS course. I manage our AWS environments now, but could totally use a full on course.
