Operations Engineering is the application of software engineering practices and principles to achieve and sustain operational excellence.
The quote above is from a re:Invent talk given by Josh Evans at Netflix. The phrasing appeals to me because it explicitly links operations and software engineering. I also recommend the talk if you’re interested in the topic of operations engineering at Netflix. (For context: Josh is my manager’s manager’s manager).
I wrote a paper review for It Never Work In Theory.
The limitation of over-engineering as a safety technique is that the extra weight and volume may begin to contribute to the very problem that it was intended to solve. No-one knows how much of the volume of code of a large system is due to over-engineering, or how much this costs in terms of reliability. In general safety engineering, it is not unknown for catastrophes to be caused by the very measures that are introduced to avoid them.
