• This course aims to provide a complete guide to AWS fundamentals, organizing knowledge about AWS services and their practical applications.

  • Learn why you use AWS's main services, what features they have, and how to utilize them.

  • Not only AWS, but also the foundational knowledge needed to understand AWS.

  • The title says beginner course, but it actually aims to cover content up to intermediate level and beyond.

• Created by a Dev Lead from a startup that has been using AWS on the front lines for 9 years.

  • Not only simple knowledge transfer, but also the know-how of actually solving problems in the field is included.
