The document details a continuous delivery journey of a Richmond, VA-based insurance comparison website launched in 2012, highlighting its shift from a monolithic architecture to a more agile delivery process. With 4 feature teams and an emphasis on rapid builds and releases, the development workflow includes automated deployment and thorough validation processes. Key metrics and tools such as Jenkins, Selenium, and Git flow are utilized to enhance reliability and speed in delivering valuable software to customers.
