This page lists a subset of use cases for [Terraform](/intro/index.html).
## 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. 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 and allows a single configuration to be used to manage multiple
providers, and to even handle cross-cloud dependencies. This simplifies
management and orchestration, helping operators build large-scale multi-cloud
infrastructures.

## Heroku App Setup
Heroku is a popular PaaS for hosting web apps. Developers create an app, and then attach add-ons, such as a database, or email provider. One of the best features is the ability to elastically scale the number of dynos or workers. However, most non-trivial applications quickly need many add-ons and external services.
@ -82,14 +99,3 @@ Terraform is not limited to physical providers like AWS. Resource schedulers
can be treated as a provider, enabling Terraform to request resources from them.
This allows Terraform to be used in layers: to setup the physical infrastructure
running the schedulers as well as provisioning onto the scheduled grid.
