Terraform modules are a powerful way to standardize cloud infrastructure deployments by encapsulating reusable configurations that can be shared across multiple environments. By using modules, you can apply the principles of infrastructure as code to ensure consistency, reduce errors, and improve collaboration within your team.

<!-- BEGIN COPY / PASTE -->
    module "vpc" {
      source = "terraform-aws-modules/vpc/aws"
      version = "3.0.0"
      
      name = "my-vpc"
      cidr = "10.0.0.0/16"
      
      azs             = ["us-east-1a", "us-east-1b", "us-east-1c"]
      private_subnets = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]
      public_subnets  = ["10.0.101.0/24", "10.0.102.0/24", "10.0.103.0/24"]
      
      enable_nat_gateway = true
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Use modules to encapsulate common infrastructure patterns like VPCs, security groups, and IAM roles.
Store modules in a version-controlled repository to track changes and facilitate collaboration.
Leverage the Terraform Registry to find community modules or publish your own for broader use.
Define input variables for modules to customize configurations without altering the module's core logic.
Ensure modules are versioned to maintain stability and predictability across deployments.
