This is the Vagrantfile I am using for my development box at home and work. It is determines how much ram is available and how I want to allocate, how many CPUs are available, and configures the VM for me. I use NFS for shared folders. Finally, starting to use "hostupdater" to keep my host machines hosts file current.

I have been doing more web development with Vagrant and VirtualBox. It's a nice way to keep my dev environment nearly the same as my production environments. Recently I was doing some front-end coding and was running into the most bizarre errors with my JavaScript.

I use Chef to manage and provision new staging and production servers in our company. It takes a lot of the headache out of managing multiple servers and allows me to fire up new web & data servers for our projects with ease. I have several cookbooks that I use to configure servers and to setup/configure websites. In a nutshell, it's rad, and website deployments have never been easier.
