It's a good lecture.. I quickly looked through the free introductory lectures that are open to the public through YouTube and blogs such as Life Coding and AWS Classroom, and while taking the Udemy AWS-C03 course, I was looking for other lectures that are more in-depth and professional problem-solving courses, and I ended up taking this course. I think it's good to look at the FAQ and Well-Architected Framework before looking at the introductory lectures and studying the dumps. It's good because it's different from the lectures that are open to the public for free, and there's new knowledge to be gained. If you have time, I think it would be helpful to look at Udemy and this lecture. Let's study hard to pass and get a job!
