Terraform
Define your cloud infrastructure as code, and let it build itself
What it is
About Terraform
Terraform lets engineers describe servers, networks, and cloud services in human-readable configuration files, then automatically provisions and manages that infrastructure across providers like AWS, Azure, and Google Cloud. It's central to modern cloud security and networking practice because infrastructure changes become versioned, reviewable, and repeatable rather than manual clicks in a console.

Always run terraform plan and actually read the diff before applying — the biggest real-world Terraform incidents come from blindly approving a plan that silently destroys and recreates a resource.
