This document provides an overview and introduction to DevOps. It discusses that DevOps involves people, processes, and tools working together. It describes how DevOps extends lean and agile principles across the entire application development lifecycle from development to operations. Specifically, it promotes a culture of collaboration between development and operations teams. It also explains how DevOps aims to address bottlenecks in the software delivery process through practices like continuous integration, deployment, and testing.

DevOps – Key Takeaways
1. DevOps is about transforming application development and deliveryin
order to acceleratedigital innovation. So DevOps is a topic for both business
and IT roles in the organization.
2. You don’t buy DevOps, you do DevOps. DevOps is an approach, a mindset –
a combination of culture, process and technology (includinginfrastructure, tools
and services).
3. DevOps is not only about the hand-off between Developmentand
Operations. DevOps is about applying lean and agile principles across the
application deliverylifecycle (biz-dev-test-deploy-operate) to achieve continuous
delivery of digital innovation. Key concepts: automation, feedback loops.
