Its been a while I am using Ansible as a tool for configuration management. There was some conditions where I created a roles with multiple dependencies, or I have to revisit an ancient roles created by someone else in the past. It doesn’t matter if the roles are well tested, how if its untested or doesn’t have tests at all? In the past, I test ansible role by creating a vagrant box and run ansible playbook in it.

What is Terraform? Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. OK, that’s the first answer when you questioning about “what is Terraform”. Terraform is a tool built by Hashicorp for infrastructure management. It’s based on Go, so you can easily install it by downloading the binary into your machine. Why Using Terraform? This is a good question, we know that there are some tools besides Terraform for infrastructure management that commonly used out there like Ansible, Chef, or CloudFormation (if you use AWS).
