What is Infrastructure as Code (IaC)?

The practice of managing infrastructure through machine-readable configuration files rather than manual processes.

IaC treats infrastructure configuration as software โ€” versioned, reviewed, and automated. This ensures consistency, repeatability, and reduces human error. Changes are tracked in version control.

Popular tools include Terraform (multi-cloud), AWS CloudFormation, Ansible (configuration management), Puppet, and Chef. IaC enables disaster recovery by rebuilding infrastructure from code.
