Building the code

Even before we get to questions about containers versus VM images, we should look at some things about the code. Developers naturally pay a lot of attention to their code. As a result, we have great tools at our disposal to build, house, and deploy code. There are some important rules to follow, though. These are mostly about making sure that we know exactly what goes into the code on the instance. It is vital to establish a strong chain of custody that stretches from the developer through to the production instance.
