I think this lecture is enough to cover all the AWS introductory courses for practical work, regardless of whether you are a job seeker, intern, or junior. I liked that it covers the AWS services you will encounter in practical work in a broad and not-so-subtle way!

    I have completed less than 30% of the course. I have tried various courses to learn AWS, but there is no course that covers such a wide range of topics while being detailed and easy to understand. It is the best course to start with AWS because it mixes theory and practice appropriately. In addition, considering the frequent changes in AWS services, I cannot express how grateful I am for the fact that this course is updated quickly and consistently.

        I am a current job seeker. This is the first time I have seen a lecture in AWS Classroom that provides theory and practice on such a wide range of AWS services, so I came across the lecture on YouTube. This lecture is like an AWS dictionary that you can look up right away during a project.
