| `azurerm_network_security_group` | Manages the Azure Network Security Group that contains a list of network security rules |
| `azurerm_subnet` | Manages the Azure Subnet |
| `azurerm_subnet_network_security_group_association` | Associates an Azure Network Security Group with an Azure Subnet within an Azure Virtual Network |
| `azurerm_private_dns_zone` | Manages Azure Private DNS zones within Azure DNS  |
| `azurerm_private_dns_zone_virtual_network_link` | Manages Private DNS zone Virtual Network Links |
| `azurerm_postgresql_flexible_server` | The Azure PostgreSQL Flexible Server that the Azure PostgreSQL Flexible Server Database will run on |
| `azurerm_postgresql_flexible_server_database` | The Azure PostgreSQL Flexible Server Database |

## Variables

| Name | Description |
|-|-|
| `name` | Name of the deployment |
| `environment` | The depolyment environment name (used for postfixing resource names) |
| `location` | The Azure Region to deploy these resources in |


## Example

```bash
>terraform plan

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

Plan: 9 to add, 0 to change, 0 to destroy.

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you run "terraform apply" now.
