# Network Drivers
|
|
|
|
Consul-Terraform-Sync uses network drivers to execute and update network infrastructure. Drivers transform Consul service-level information into downstream changes by processing and abstracting API and resource details tied to specific network infrastructure.
|
|
|
|
Consul-Terraform-Sync is a HashiCorp solution to Network Infrastructure Automation. It bridges Consul's networking features and Terraform infrastructure management capabilities. The solution seamlessly embeds Terraform as network drivers to manage automation of Terraform modules. This expands the Consul ecosystem and taps into the rich features and community of Terraform and Terraform providers.
|
|
|
|
The following table highlights some of the additional features Terraform and Terraform Enterprise offer when used as a network driver for Consul-Terraform-Sync. Visit the [Terraform product page](https://www.hashicorp.com/products/terraform) or [contact our sales team](https://www.hashicorp.com/contact-sales) for a comprehensive list of features.

## Understanding Terraform Automation
|
|
|
|
Consul-Terraform-Sync automates Terraform execution using a templated configuration to carry out infrastructure changes. The auto-generated configuration leverages input variables sourced from Consul and builds on top of reusable Terraform modules published and maintained by HashiCorp partners and the community. Consul-Terraform-Sync can also run your custom built modules that suit your team's specific network automation needs.
|
|
|
|
The network driver for Consul-Terraform-Sync determines how the Terraform automation operates. Visit the driver pages to read more about the [Terraform driver](/docs/nia/network-drivers/terraform) and the [Terraform Cloud driver](/docs/nia/network-drivers/terraform-cloud).
