If a new fridge arrives, the urge to just plug it, fill it with beverages and enjoy a cold one is big. But the setup actually requires quite some steps to ensure that the device runs reliably for a long time with low maintenance, so does a proper onboarding process. In this blog post I will use this odd analogy to describe my onboarding process as a Software Engineer in the Dev Team at cloudscale.
