By: Paul Swartout

Overview of this book

Over the past few years, Continuous Delivery (CD) and DevOps have been in the spotlight in tech media, at conferences, and in boardrooms alike. Many articles and books have been written covering the technical aspects of CD and DevOps, yet the vast majority of the industry doesn’t fully understand what they actually are and how, if adopted correctly they can help organizations drastically change the way they deliver value. This book will help you figure out how CD and DevOps can help you to optimize, streamline, and improve the way you work to consistently deliver quality software. In this edition, you’ll be introduced to modern tools, techniques, and examples to help you understand what the adoption of CD and DevOps entails. It provides clear and concise insights in to what CD and DevOps are all about, how to go about both preparing for and adopting them, and what quantifiable value they bring. You will be guided through the various stages of adoption, the impact they will have on your business and those working within it, how to overcome common problems, and what to do once CD and DevOps have become truly embedded. Included within this book are some real-world examples, tricks, and tips that will help ease the adoption process and allow you to fully utilize the power of CD and DevOps

Let's compare your software-release process to a flowing river (I did say it was a bit of a tangent):

  • At the very beginning, many small streams flowed downhill and converged into a river. This river flowed along, but the progress was impeded by a series of locks and a massive manmade dam:
  • The river then backed up and started to form a reservoir.
  • Every few months, the sluice gates were opened and the water flowed freely, but this was normally a short-lived and frantic rush.
  • As you identified and started to remove the manmade obstacles, the flow started to become more even, but it was still hindered by some very large boulders further downstream:
  • You then set about systematically removing these boulders one by one, which again increased the flow; this, in turn, started to become consistent, predictable, and manageable.
  • As a consequence of removing the obstacles...
