Safe Software Deployments: The 180 Rule

The 180 Rule' is a method used by developers to overcome the fear of deploying software. It involves automating the deployment, monitoring, and rollback process to ensure that any issues are quickly detected and fixed. The rule aims to reduce the time spent on failed deployments from hours or days to just three minutes. This requires creating rigorous scripts and metrics, and ensuring reliable detection and fixation of problems. The goal is for environments to be able to deploy software to production and roll it back if needed within a short timeframe, allowing developers to feel more confident about deploying software.
