This is a great lecture that provides direction for designing backend systems. Until now, I haven't thought much about it since I've only developed using the typical monolithic approach, but I'll try applying these concepts one by one while working on side projects. Thank you for the great lecture!

This was very helpful! Thank you!

It's good for starting to study system design.

It's much easier to understand and organize everything at once when learning through video materials with explanations like this, rather than just vaguely reading books on the market!

Thanks to you, I learned a lot. Thank you!

The overall flow is very easy to follow. Thank you for the great lecture.

This lecture made me think about the architectural structure of the projects I create. It also made me consider the trade-offs that come with choosing different structures. My satisfaction with this lecture was high, so I naturally look forward to the next one. Looking at the comments, I see you're planning lectures with more advanced content, which I'm excited about. I learned a lot. Thank you.

This is an excellent course for getting the big picture of system design! The instructor pinpointed and explained concepts that I had heard about somewhere before but never fully understood, which really broadened my knowledge. In particular, by focusing on 'why' rather than 'how', I was able to realize that there are no correct answers in design and that everything is the result of trade-offs. Also, through this course, I was able to get a sense of which parts of my projects I should focus on when appealing in interviews. I highly recommend this course to anyone who is learning system design for the first time or preparing for interview preparation!!

When I first did a team project, I had such little understanding of architecture that I struggled a lot, so I took this course based on that memory, and I'm leaving with a lot of learning.

It was a time to briefly experience the overall architectural forest.
