Terraform

Terraform is an open-source Infrastructure as Code tool developed by HashiCorp that allows engineers to define and provision infrastructure — including network resources — using a declarative configuration language called HCL (HashiCorp Configuration Language). Instead of manually creating networks, subnets, firewall rules, and load balancers through a cloud console, Terraform lets you describe the desired state of your infrastructure in code and then automatically creates or modifies resources to match that state. It supports all major cloud providers and many network vendors, making it a popular choice for managing cloud networking infrastructure consistently and repeatably.
