What would you say is the job of a software developer? A layperson, an entry-level developer, or even someone who hires developers will tell you that job is to … well … write software. They’d say that the job involves writing some software, sure. But deep down it’s about the purpose of software. Pretty simple.

In the same way that we have moved from a few big software releases a year to continuous delivery of many small changes, we need to move from annual disaster recover tests or suffering when things actually break, to continuously tested resilience.
