This is the best class and instructor I have had in the last decade. What the instructor was able to convey was the exact information I needed, and I am grateful I had such a knowledgeable instructor. I will try and get the same instructor for future courses. I will recommend Ruben to my co-workers and associates as a top-notch, peerless instructor when it comes to relating AWS & Cloud technologies to people seeking this knowledge. Up until this point I have mostly utilized self-study, but after taking Ruben's class I will now look to more instructor-led classes, especially if the instructors have the proficiency of knowledge that Ruben displayed while teaching this difficult course.
