If you've never heard of the powerful tool and you need automation around creating and configuring multiple virtual machines, you really should check it out. If you're curious as to how it's being used and what kind of things it's used for, check out this new post from Erika Heidi based on some research she recently did (and a survey she received some good feedback to).

From 11 to 14 of January, 720 Vagrant users from different sources (Twitter, IRC and the official Vagrant mailing list) answered a quick form I created to find out how people are using Vagrant. I’m currently in the process of writing a LeanPub book about this tool, and I was really curious especially about the provisioners usage.

She's put together the results in the form of an easy to read infographic with details about:

• The most popular provisioners
• The percentage of boxes running with OS
• The percentage of languages on the boxes
• The OS most Vagrant users use

...and finally the answer(s) to the question of "why vagrant?" but I'll leave it to you to read the post to find out that one.
