As I implemented micro services without thinking, I discovered service problems as they arose. So I took this course to see the big picture, and I’m glad I did. To be honest, I didn’t understand everything, but I nodded along to the parts I had done before. And in the architecture section, I learned about hexagonal architecture and it cleared up a lot of things for me. As the saying goes, a picture is worth a thousand words, but there were still some parts I didn’t understand, and there were things I hadn’t thought about regarding DIP, and it was a course that covered a lot of different topics.
