This course is designed to help learners obtain the Terraform Associate certification from HashiCorp. 

You’ve likely picked up this course because you dabbled in Terraform as a hobbyist or in a
development environment, and you’re excited about the possibilities of deploying Infrastructure 
as Code (IaC). It will enable you to sharpen your skills and prove your knowledge with a certification from HashiCorp. Terraform is an amazing tool to deploy Infrastructure as Code in a cloud-agnostic way. We’re excited to share our accumulated knowledge with you through this course.

# Outputs

Output values expose the attributes stored in local resources for external consumption. This can be a confusing process at first glance.
 
## Uses of output values
Let's look at a few uses for outputs.

* A child module can use outputs to expose a subset of its resource attributes to a calling module.
* A root module can use outputs to print certain values in the CLI output after running `terraform apply`.
* When using a remote state, root module outputs can be accessed by other configurations via a `terraform_remote_state` data source.

When we create a resource in a module, the attributes of that resource can be referenced throughout the rest of that module. However, those attributes aren’t directly available for consumption by other modules or as a data source when using remote state. Output values are a way to name, transform, and expose the information stored in attributes to the consumer of our module. If an attribute isn’t exposed as an output, it’s not available to a calling module.

An output value exported by a module is declared using an `output` block. The example below shows one of the outputs of the official `vpc` module.
