Creating An Azure Virtual Network(VNET) And Multiple Subnets: A Step-By-Step Beginner's Guide

Source: Dev.to

Introduction: Virtual Network allows resources running in Microsoft Azure, like Virtual Machines, Storage Accounts, Applications, to communicate with each other, internet, and even on-premises network environments. A Subnet is a subdivision of your VNet. It allows you to divide your network into smaller, logical sections and assign different resources to different sections based on their purpose. Subnets are logical segments of a Virtual Network which assist in organizing and securing network resources. In this project, I have designed an Azure Virtual Network with three separate Subnets. Objectives The objectives of this project are to: Prerequisites Before starting, ensure you have: .An active Azure Subscription .Access to Azure Portal .Internet Connection .Appropriate permissions to create Azure resources Azure Portal: https://portal.azure.com Architecture Overview Azure Virtual Network (10.0.0.0/16)

Step 1: Sign in to Azure Portal Open Azure Portal. https://portal.azure.com. Sign in using your Azure credentials.

Step 2: Create a Resource Group Search for Resource Groups on search bar and click on Resource group from the dropdown

Click on Create

Type the Resource group name, select the region and click Next

Apply tags to your resources to logically organize them by categories and click Next

Review the resources group and click on Create

Click on Resource Group on the left to bring out the resource group you created

Step 3: Create a Virtual Network

Click on +Create(With a plus sign)

2. Define Basic Settings Subscription: Select your subscription

3. Define IP Address Space

_NOTE: Whenever you create your VNet there is a subnet that comes with it defaultly. We delete the subnet and create our own Subnet

• Click Next -> Review + Create

-4. Click on Create, the deployment will be submitted, and the VNet will be created

_Step 4: Configure Subnets _ Now, let’s configure the Three subnets within the virtual network: Type Subnet on the search bar and click on Subnet

• Click + Add subnet to define each subnet

Configure each subnet as follows: Subnet Name: Enter a name for the subnet (e.g., Subnet1, Subnet2,Subnet3, etc.).

• Creation of Subnet 1

• Creation of Subnet 2

• Creation of Subnet 3

To have a view of the subnets created, click on Settings on the left pane and then on Subnets

Congratulations! You have successfully created an Azure virtual network with Three subnets using the address space (10.0.0.0/24)
