Vagrant - the essence of DevOps in a tool

Traditionally, developers would write their applications without any thought as to what system it was going to be deployed on in production. It was also very difficult for them to understand how their software would react when releasing it into a production environment as they didn't really understand how that environment was configured. What if there was a way that developers could create the scripts needed to install dependencies and get the software running as it is developed? Vagrant does exactly this, it is a tool to create and configure lightweight, reproducible, and portable development environments. In this session, I will show you how to create a development work flow that will allow developers to use Vagrant to create a real continuous delivery pipeline. This means understanding the environment needs as well as what is needed to run the software. I will also show how we, at OpenTable, integrate Vagrant into our pipeline to allow us to create a good acceptance testing environment against known data sets rather than having brittle test.
