Infrastructure as Code (IaC)
Definition
Infrastructure as Code (IaC)
Infrastructure as Code (IaC) manages and provisions cloud infrastructure through machine-readable configuration files. Tools like Terraform, AWS CDK, and CloudFormation replace manual console operations with version-controlled, reproducible definitions.
In detail
Manual infrastructure provisioning is slow, error-prone, and impossible to audit. IaC makes infrastructure reproducible: the same configuration produces the same environment every time. Changes are reviewed through pull requests, just like application code.
IaC enables drift detection (comparing actual state to desired state), automated compliance checks, and rapid disaster recovery. It is a prerequisite for mature DevOps and cloud governance practices.
How Tallence helps
Tallence migrates manual infrastructure provisioning to Terraform or AWS CDK, making your environments reproducible, version-controlled, and auditable.
