Usually, when you work with a version control system like git, development happens in multiple branches. It’s funny to see people’s faces when you tell them that the author of Continuous Delivery, Dave Farley, advocates “no branches”. I had that same surprised face myself the first time I heard that concept. But, so far, I haven’t really worked somewhere where no branches were used.
The term microservice has been getting a lot of hype and attention. I have to admit that I fail to understand what’s the big deal about it. The best practices about microservices are similar to the ones we should apply to everyday software design. Avoid tight coupling. Single responsibility principle. Keeping things simple. Even those principles go back to the old Unix mantra of doing one job and doing it well (and that’s from 1978). And even that could in turn be labelled just “common sense”.
