It was a great opportunity to learn things I didn't know before. Thank you!

This was truly a perfect course. It was so engaging that I completed half of it in just one day, and for practitioners building monitoring systems, there's so much content that makes you think "I need to save this and keep watching it." It wasn't just a simple feature introduction, but provided step-by-step configuration and operational know-how that can be immediately applied in real-world practice, which was extremely helpful. Highly recommended.

I was curious about management and found out through this course. Thank you. The lecture volume was low while the Line notification sound was loud, which startled me several times. It would be great if you could adjust the volume levels.

I was able to gain an overall understanding of AWS fundamentals. Through the hands-on practice, I acquired concepts that I can actually use in the future. Thank you for the great lecture.^^
