Vagrant allows developers to create identical development environments to production by setting up virtual machines from a "base box" that can be provisioned using tools like Puppet. This allows developers, designers, and ops teams to quickly set up consistent environments, test configurations, and focus on their work without installation issues. Vagrant addresses common needs like having identical environments, easy setup, and using preferred tools by automating the setup of virtual machines that mirror production.

1. Vagrant + Puppet = #WIN

3. As a Developer, I want
An environment that is identical to production
An environment that is easy to setup
The same environment that everyone in my team uses
To use the tools, editors, etc. that I am most comfortable with

4. As an Ops person, I want
To be able to quickly develop, spin up and test different environments
Test things like shell scripts, Chef/Puppet configurations

5. As a Designer, I want
To quickly setup the app so I can focus on design
No install fests!
