- Not all developers want to be sysadmins- New employees or contractors starting

- Works on my machine syndrome- Advantage to running a full stack locally- local service based architectures

What is Vagrant?


- Automated virtual machine creation using Oracle’s VirtualBox

- Automated provisioning of virtual environments using Chef or Puppet

- Full SSH access to created environments

- Assign a static IP to your VM, accessible from your machine

- Forward ports to the host machine

- Shared folders allows you to continue using your own editor

- Package environments into distributable boxes

- Completely tear down environment when you’re done

- Easily rebuild a complete environment with a single command
