Continuous delivery journey - Montgomery county JUG
The document describes the journey of an insurance comparison website moving from a yearly release cycle with 12 releases in 2012 to a continuous delivery model with daily releases by 2014. It discusses how the company transitioned to using Kanban and feature teams to allow independent delivery of features as soon as they are ready for production. This enables production deployments every day with a focus on fast, reliable builds; automated testing and deployment; and production monitoring.
