Vagrant Up: your environment

It’s Friday 3pm. Your boss comes to you and asks you to set up a development environment for the new employee that arrives on Monday.

On another day, you have a sudden traffic spike and need to add a new server. Now you have to carefully follow a procedure without forgetting a step.

Sounds familiar?

In this presentation, Yann Larrivée will show you how Vagrant and Puppet can dramatically reduce the time needed to accomplish these tasks ans reduce the number of mistakes.
