A Terraform module is a container/template for multiple resources that are used together. Modules are a way to organize and reuse code in Terraform, making infrastructure management more efficient and maintainable.

We first define the resource templates, and then we call the templates from outside of the module structures and we can even modify them as per our needs.

A typical module module looks something this this:
