Infrastructure as Code (IaC) transforms the management and provisioning of IT infrastructure by utilizing code to automate processes, thereby enhancing efficiency, scalability, and innovation. It allows system administrators and IT practitioners to define infrastructure configurations using declarative or imperative programming languages, ensuring consistency, repeatability, and reduced manual intervention. Popular IaC tools such as Terraform, AWS CloudFormation, Azure Resource Manager, Google Cloud Deployment Manager, Ansible, Pulumi, Chef, and Vagrant facilitate infrastructure automation across various cloud and on-premises environments. These tools enable the deployment, configuration, and management of resources through machine-readable definition files, supporting diverse platforms like AWS, Azure, Google Cloud, and more. By adopting IaC, organizations can streamline infrastructure provisioning, enforce consistent configurations, and leverage collaboration through version control, ultimately accelerating deployment cycles and improving resource utilization.
