# Use Cases
Before understanding use cases, it's useful to know [what Terraform is](/intro/index.html).
This page lists some concrete use cases for Terraform, but the possible use cases are
much broader than what we cover. Due to its extensible nature, providers and provisioners
This page lists a subset of use cases for [Terraform](/intro/index.html). Due to its extensible nature, providers and provisioners
can be added to further extend Terraform's ability to manipulate resources.
## Heroku App Setup

allows the network to better support the applications running on top. Most SDN
implementations have a control layer and infrastructure layer.
Terraform can be used to codify the configuration for software defined networks.
This configuration can then be used by Terraform to automatically setup and modify settings by interfacing with the control layer. This allows configuration to be
versioned and changes to be automated. As an example, [AWS VPC](https://aws.amazon.com/vpc/) is one of the most commonly used SDN implementations, and [can be configured by Terraform](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/vpc).

## Multi-Cloud Deployment
It's often attractive to spread infrastructure across multiple clouds to increase fault-tolerance. By using only a single region or cloud provider, fault tolerance is limited by the availability of that provider. Having a multi-cloud deployment allows for more graceful recovery of the loss of a region or entire provider.

Realizing multi-cloud deployments can be very challenging as many existing tools
for infrastructure management are cloud-specific. Terraform is cloud-agnostic
