This document discusses DevOps tools and practices used in VMware's private cloud. It provides an overview of tools like Jenkins for continuous integration, Gerrit for code reviews, and describes how VMware uses these tools to rapidly deploy applications to its private cloud in a cost effective and automated way. The private cloud has grown significantly over time and now supports over 300,000 VMs across multiple data centers globally using technologies like vSphere, vSAN and vRealize Automation.
