Story In previous post, I already share my experience when tried to automate manual process by created script to automatically create configs based on the input in requests. We found that the script are useful enough at that time, and reduced number of incidents caused by misconfiguration (yay!). Unfortunately, we faced with issues when the provisioned infrastructure not work as expected which caused by several things, example: invalid port definition which (again) inputted by human. ...

Story Did you ever worked in repetitive tasks? I was worked as an operational cloud infrastructure engineer. Starting from received several ticket from developers who needs infrastructure, gathering informations for their needs, double check the requests, and everything done manually by myself.. Ouch! Even worse if we missed something from the request, ta-daaa! Incident happened and another requests got delayed. It does happened to me (and my team) about past one-half years ago.

After that, re-run the playbook and check by login into the box. The testing are created together with playbook creation. Which for me is very time consuming. ...

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). ...
