Infrastructure as Code

Infrastructure as Code (IaC) is the practice of managing and provisioning infrastructure — including networks, servers, and cloud resources — through machine-readable configuration files rather than manual processes or interactive tools. Instead of clicking through a web console or typing commands into a CLI to set up a network, IaC lets you write code that describes exactly what the infrastructure should look like, check that code into version control, and apply it automatically and repeatably. This brings software development practices like version control, code review, and automated testing to infrastructure management, making changes more reliable, auditable, and consistent across environments
