Configure Azure Networking Components, Such As Virtual Networks And Subnets

Azure Networking is critical for establishing connections and managing resources within Azure. This article will help you configure essential Azure networking elements like Virtual Networks(VNets) or Subnets.

Step 1: Log into Azure Portal

Start by accessing the Azure Portal at https://portal.azure.com. Sign in using your credentials.

Step 2 Create a Virtual Network

  1. Click on “Create an resource” from the left-hand side menu.
  2. Type “Virtual Networks”, into the search box.
  3. Click the “Create” button.

Step 3 Basic Settings

  1. Select the Subscription and Resource Group from the “Basics”. If you want, you can create your own resource group.
  2. Enter a name for the Virtual Network.
  3. Select the Region you want to deploy VNet. It is best to choose a close region to your user base in order to get lower latency.

Step 4 – Address Space Configuration

  1. In the section “IP Addresses”, you should specify the Addressspace that your VNet uses (e.g. 10,0,0,0/16). This range will be used to define the entire addressable network space.
  2. Click “Add”, if you want to add additional ranges.

Step 5 Create Subnets

  1. In the subnets section, you can configure default subnets or add new subnets.
  2. Click on “+Subnet.”
  3. Give a name to the subnet. (e.g. Subnet1) and define the Address range. (e.g. 10.0.1.1/24). Make sure this range is part of your VNet’s address space.
  4. Configure optional setting, such a Network Security Groups (NSG), or route tables as needed.
  5. Click “Add”, and you will be able to create your subnet.

Step 6 Review and Create

  1. After configuring a subnet, review all settings using the “Review + create” tab.
  2. Click “Create”, after you have verified that your configurations are correct, to deploy your VNet.

Step 7 – Configure Network Security Groups

  1. You may want apply security rules to control traffic inbound and output. Go back to the Azure dashboard.
  2. Click on “Create”.
  3. Define a name, and attach it the previously created Subnet.
  4. Create specific inbound/outbound rules within NSG that are based on the security requirements.

Step 8 – Connecting Resources with the VNet

Once your VNets and Subnets are configured, it is possible to attach resources.

  1. Select your VNet, and desired subnet when creating a VM.
  2. Ensure that all your resources can now effectively communicate with each other within the defined networks components.
