# Azure Resource Manager Provider

The Azure Resource Manager provider is used to interact with the many resources
supported by Azure, via the ARM API. This supercedes the Azure provider, which
interacts with Azure using the Service Management API. The provider needs to be
configured with the credentials needed to generate OAuth tokens for the ARM API.

Use the navigation to the left to read about the available resources.

## Example Usage

```
# Configure the Azure Resource Manager Provider
provider "azurerm" {
  subscription_id = "..."
  client_id       = "..."
  client_secret   = "..."
  tenant_id       = "..."
}

# Create a resource group
resource "azurerm_resource_group" "production" {
    name     = "production"
    location = "West US"
}

# Create a virtual network in the web_servers resource group
resource "azurerm_virtual_network" "network" {
  name                = "productionNetwork"
  address_space       = ["10.0.0.0/16"]
  location            = "West US"
  resource_group_name = "${azurerm_resource_group.production.name}"

  subnet {
    name           = "subnet1"
    address_prefix = "10.0.1.0/24"
  }

  subnet {
    name           = "subnet2"
    address_prefix = "10.0.2.0/24"
  }

  subnet {
    name           = "subnet3"
    address_prefix = "10.0.3.0/24"
  }
}

```
