Terraform on Ubuntu 18.04 Minimal enables users to define and provision infrastructure resources using a declarative configuration language. With Terraform, you can manage and automate the creation, modification, and versioning of infrastructure components, such as virtual machines and networks. Terraform's strength lies in its ability to maintain infrastructure as code, allowing for version control, collaboration, and the creation of reproducible, scalable, and consistent infrastructure deployments. It is a key tool in modern DevOps and cloud-native workflows, providing infrastructure agility and reducing manual configuration efforts.
