Frequently Asked Questions

What is infrastructure as code?
Infrastructure as code (IaC) is the practice of managing and provisioning infrastructure through machine-readable configuration files rather than manual processes. It enables version control, peer review, and automated deployments for your infrastructure.
What are the benefits of IaC?
IaC provides repeatability, version control, collaboration via pull requests, automated testing, drift detection, and disaster recovery. It eliminates manual configuration errors and documents your infrastructure as code.
Which IaC tool should I learn first?
Terraform is the most widely adopted multi-cloud IaC tool and the best starting point. If you work exclusively in AWS, CloudFormation or CDK are also solid choices. Pulumi appeals to developers who prefer general-purpose languages.
