Vagrant Who has tried Vagrant before? Tuesday, 19 March 13 

Setting up a development environment • Often considered a right of passage • Takes hours, often requires support • Requires documentation that’s always frequently out of date • Breaking your development environment can kill productivity for days • Produces unpredictable results Why Vagrant? Tuesday, 19 March 13 

Your development and production environment are not the same! • Different OS? • Different version of PHP/Python/Ruby? • Diverged package versions? • Different default configuration files? Why Vagrant? Tuesday, 19 March 13 

• Update a website with a new feature. • The feature relies on a PHP module that is required by your web app • Module already installed on your laptop because another project that is hosted elsewhere needed it • It’s not a the server you deploy to, so the entire website stops working • You have no idea why, the same code worked on your machine • It worked on my machine! Why Vagrant? Tuesday, 19 March 13 

• Vagrant configuration should be stored in version control • New developers can start developing quicker • Switch between projects, versions of PHP, languages with a few commands Why Vagrant? Tuesday, 19 March 13 

• Vagrant lowers development environment setup time • Maximizes dev/prod parity • Makes the “works on my machine” excuse a relic of the past. from vagrantup.com Why Vagrant? Tuesday, 19 March 13
