When I started coding, my professors taught me that copy-pasting code from the internet is the worst thing a dev can do. It almost felt like an army boot camp, with the drill sergeant screaming: “What will you do in the battlefield, soldier? What will you do when you’re a full-stack developer, and you can’t…

By making it easier than ever to add powerful new microservices, Kubernetes has become a driving force behind companies breaking up monolith apps and transforming them into microservice architectures. But as their numbers grow, the cost of managing microservices and the dependencies between them increase exponentially as well. This makes things more complicated than many…
