I've only heard the term DevOps and had just created an AWS ID when I suddenly needed to set up a Linux environment on AWS, which is why I took this course. I followed the curriculum you created using my actual environment setup as an example, and it worked better than expected. I'm truly grateful. Personally, this was my first time properly encountering the concepts of DevOps and IaC, and it's a whole new world~ It was meaningful not only in terms of helping with my work, but also in discovering how convenient this world is that I didn't know about. It was such a great course!
