Learning your way around a new software stack is challenging enough without having to spend multiple cycles on the install process. Instead, we have packaged such stacks into pre-built Oracle VM VirtualBox appliances that you can download, install, and experience as a single unit. Just assemble the downloaded files (if needed), import into VirtualBox (available for free), import, and go!
Developer VMs are currently available in these flavors, with more to come. (Some of them are designed to support Developer Day workshops, and have specific hands on labs embedded in them, but they're available to all.) Be sure to install VirtualBox first.
