Now, instead of deploying one application, you need to deploy 100s of them. It sounds doable but not efficient, right? That's exactly where Infrastructure as Code comes into play. It enables you to automate the provisioning of infrastructure using code instead of manually doing it via the GUI. There are several IaC tools available today — Terraform, Pulumi, AWS CloudFormation, Azure Resource Manager (ARM), and Google Cloud Deployment Manager, to name a few. Among these, Terraf
