I think this course also helped me learn how to design systems based on AWS. It was useful not only for learning the theory, but also for designing infrastructure in a practical context. I also feel it indirectly helped me prepare for the AWS-SAA certification. In particular, it was valuable to understand how real cloud networking components such as VPCs, ALBs, and NLBs work, with the help of diagrams.
The network architecture, which had once seemed vague, became more organized in my mind, giving me the confidence to design infrastructure myself. It was a worthwhile course that I would recommend to anyone looking to strike a balance between theory and practice.
