#### Creating a resource group for all resources under a specified name and location

```hcl

resource "azurerm_resource_group" "DevOps" {

  name     = var.name         # Name of the resource group, provided as a variable

  location = var.location     # Location of the resource group, e.g., "East US"

}

```

- Sets up a Network Security Group (NSG) within the resource group to control subnet traffic

```hcl

resource "azurerm_network_security_group" "DevOps" {

  name                = "devops-security-group"              # Unique name for the NSG

  location            = azurerm_resource_group.DevOps.location # Uses location of the resource group

  resource_group_name = azurerm_resource_group.DevOps.name     # Assigns NSG to the created resource group

}

# Creates a Virtual Network with defined subnets within the specified resource group

resource "azurerm_virtual_network" "DevOps" {

  name                = "devops-network"                     # Name for the virtual network

  location            = azurerm_resource_group.DevOps.location # Same location as the resource group

  resource_group_name = azurerm_resource_group.DevOps.name     # Assigns to the existing resource group

  address_space       = var.address_space                      # CIDR address space for the VNet, provided as a variable

  # Public subnet configuration

  subnet {

    name             = "public"                               # Name of the subnet for public resources

    address_prefixes = var.subnet_address_prefixes["public"]  # Address prefix for the public subnet from variable map

  }

  # Private subnet configuration, protected by a Network Security Group (NSG)

  subnet {

    name             = "private"                              # Name of the subnet for private resources

    address_prefixes = var.subnet_address_prefixes["private"] # Address prefix for the private subnet from variable map

    security_group   = azurerm_network_security_group.DevOps.id # Associates NSG to manage traffic rules

  }

  tags = {

    environment = "production"                                # Tags for easier resource identification

  }

}
