This document discusses the use of CI/CD (continuous integration and continuous delivery) pipelines to safely and quickly deliver code from development to production. It outlines the tools used, including BitBucket, Jenkins, Docker, and Mesos. It describes build conventions and how the build infrastructure is scaled horizontally. The deployment flow and types of operations like deploy, start, stop, and restart are explained. Auto healing, saving money, and the need for a PAAS platform are also covered. Build and deployment demos are included to demonstrate the workflows.
