Infrastructure as Code
Last updated March 25, 2026
Infrastructure as Code manages cloud infrastructure through code files rather than manual configuration.
IaC tools like Terraform, Pulumi, and CloudFormation define infrastructure in code that can be version controlled and reviewed. AI enhances IaC by generating configurations from descriptions, detecting drift, and enforcing policies.
