This document provides an introduction to DevOps. It defines DevOps as a software development method that stresses communication, collaboration, integration, automation, and measurement between software developers and IT professionals. Traditionally, these groups worked in silos with barriers between development and operations. DevOps aims to break down these silos by having development and operations work more closely together through practices like configuration management, infrastructure automation, deployment automation, and monitoring. This mindset shift and cultural change can provide benefits like improved feedback, collaboration, agility, disaster recovery, and faster testing and deployment. Common DevOps tools include infrastructure as a service providers, virtualization platforms, and containerization tools.
