Test-Driven Infrastructure with Chef

Book Description

The advent of modern programming frameworks such as Rails and Django, together with the ready availability of virtualisation, and the explosion of interest in configuration management tools such as Puppet and Chef has revolutionised the web operations world. In this book, Stephen Nelson-Smith makes a case for introducing acceptance test driven infrastructure development as a way to deliver value and reduce risk. Developing infrastructure with Opscode Chef, and testing it using Cucumber, he explains how to build a test environment that allows end-to-end testing of the whole infrastructure to tease out dependencies and hidden sideeffects. Finally, the applicability of agile/lean mainstays Continuous Integration and Continuous Deployment are discussed, together with a call to rethink monitoring as the natural extension of acceptance test driven development.
