Thus, learning about Terraform modules for AWS shouldn't be a big deal for you. We should be able to easily draft AWS modules and consume them for infrastructure provisioning in AWS. Let's try to understand how we can write a module for AWS. To explain this, we have taken an example of a VPC with a subnet.
