Infrastructure as Code, or IaC, is the practice of defining infrastructure with code or configuration files. Instead of manually clicking through consoles, teams describe resources in a repeatable way.
What IaC can manage
IaC can create networks, servers, databases, storage, permissions, load balancers, and many other cloud resources. It supports version control, review, automation, and repeatable environments.
Why IaC matters
Manual infrastructure changes are hard to track and repeat. IaC helps make cloud environments more predictable, especially when paired with monitoring and deployment pipelines.
IaC turns infrastructure into something teams can review and rebuild.
