I am a computer science student who is about to graduate and is aspiring to become a data engineer. While creating a portfolio related to employment, I had many concerns about how to configure pipelines and architectures for processing big data, and how to set up an AWS environment to use it efficiently at the lowest cost possible. Through this lecture, I gained tremendous insight and know-how. In particular, I am glad that I gained a lot of knowledge about various frameworks that handle big data, and that I was inspired to delve into which direction I can go in the future. It was like a shower after a drought. I recommend this course to students who are aspiring to this field like me.
