Terraform in Depth is now in print! This has been such a ridiculous journey and I'm so excited to see the finished work. I got my copies the other day, and Blip the Cat seems to think they're new furniture.
To celebrate it's release you can get my book for half off with the coupon code PBhafner from the Manning website: http://mng.bz/XqYl

As many of you know, I'm writing a book about Terraform. What you probably didn't know is I have a coauthor.
While his knowledge of Terraform is limited, you can't deny that enthusiasm.
