I can’t speak for most programmers, but I started my career by taking courses online. That’s right, the courses I learned from my undergraduate degree are too theoretical for anything in the real world, so I took upon myself to learn about web/app development. It didn’t take long as there are very good resources out there on websites like Udemy, Coursera, Pluralsight, edX and more. Pretty soon, I reached the point where all web developers would reach at some point of their career, learning micro-service. It’s all about Docker, container, Kubernetes and orchestration. Feel lost yet? Well I did. Not because all of these terms are overwhelming because the courses that teach these things are pretty reasonably paced, but, as soon as you finish the course, you forget how to do micro-service. I have figured out the reason why.
