The best part about about this tool, dubbed "Terraform", is that it's free under the Apache 2.0 license. Here's some bullet points from UrbanCode's announcement:
- Works on top of Amazon EC2 and VMWare vSphere, with additional providers on the way
- Configuration Management via integrations with Puppet and Chef
- Virtual environment provisioning with the push of a button
You can find a usage of Terraform on this page, and you can download the code from here via GitHub. If setting up the virtual environments is your deal, you owe it to yourself to check out this new tech.
