In a previous article I went through the steps needed to create your own private, autoscaling, WebPageTest setup in Amazon AWS. It wasn’t particularly complicated, but it was quite manual; I don’t like pointing and clicking in a GUI since I can’t easily put it in version control and run it again and again on demand.
Fortunately, whatever you create within AWS can be described using a language called CloudFormation which allows you to define your infrastructure as code.
Unfortunately it’s not easy to understand (in my opinion!) and I could never quite get my head around it, which annoyed me no end.
In this article I’ll show you how to use Terraform to define your private autoscaling WebPageTest setup in easily understandable infrastructure as code, enabling an effortless and reproducable web performance testing setup, which you can then fearlessly edit and improve!
