This document discusses the author's experience developing Ruby on Rails applications on Ubuntu and the issues they encountered. It then explores using virtual machines and vagrant as alternatives. The author tests VirtualBox, VMWare Workstation, and vagrant. Vagrant provides portable development environments using configuration files and industry standard provisioning tools. The author finds vagrant useful for ensuring environments are consistent between computers. The document also introduces puppet as a provisioning tool that can be used with vagrant to automate installing software and configurations.

VMWare Workstation

16. Vagrant /veigrənt/
Free
Why Vagrant ?
● portable work environments
● configurable, reproducible
● stands on the shoulders of giants
● industry-standard provisioning tools
● isolation

19. ❖ Back to Virtualbox, VMWare: Synced folder
❖ Provision
❖ Puppet /pʌpit/
And Moreeee

20. “A provisioning tool”
package { 'build-essential':
ensure => installed
