Let's say you want to try a new operating system like Linux or Windows. Or, you want to have a clean machine with no software installed. Or, maybe you want to create a test deployment environment on your laptop for free. You can do all of these things using virtual machines. VirtualBox is a popular, free, virtual machine program from Oracle. Vagrant lets us configure and script our virtual machines using a configuration file we can check into source control. Together, these tools provide a powerful way to create and share environments. In this video we'll install Node.js and create a server on our virtual machine that we can access from a browser.
