Docker (and by extension, microservices based architecture) has expanded our horizons with respect to how the industry builds and supports applications at scale. It’s changed the way we think about our code, what production looks like, and how we live. But in our rush to embrace this exciting new paradigm, are we throwing away the lessons of the past?
