Using Terraform

Terraform is another Infrastructure as Code (IaC) tool that is developed by HashiCorp. You might wonder why it is called an IaC tool. The reason is you can define how your infrastructure needs to be using code, and Terraform will help you deploy it. Terraform uses HashiCorp Configuration Language (HCL); however, you can also use JSON. Terraform is supported in macOS, Linux, and Windows.

Terraform supports a wide range of Azure resources such as networks, subnets, storage, tags, and VMs. If you recall, we discussed the imperative and declarative ways of writing code. Terraform is declarative in nature, and it can maintain the state of the infrastructure. Once deployed, Terraform remembers the current state of the infrastructure.

As in every section, the first part of the process involves the installation of Terraform. Let's proceed with the Linux installation of Terraform.
