HOW TO CREATE AN AZURE VIRTUAL NETWORKS

Iniobong Ema — Fri, 18 Apr 2025 10:38:47 +0000

INTRODUCTION

In this write-up, I am going to show you how to create a Virtual Networks in Microsoft Azure.

Before we start building our virtual networks in the Azure portal, let’s understand what an Azure virtual network is all about

What is Azure Virtual Network?

Azure virtual networks and virtual subnets enable Azure resources, such as VMs, web apps, and databases, to communicate with each other, with users on the internet, and with your on-premises client computers. You can think of an Azure network as an extension of your on-premises network with resources that link other Azure resources.

Azure virtual networks or also known as Azure VNETs are the basic building block of your private network on the Azure Cloud. These virtual networks are the logical constructs that in the underlay utilize the physical infrastructure in Microsoft datacenters across different regions thus reaping the benefits i.e., scale, and high availability. It is the representation of your private network in Azure that is logically isolated from other virtual networks in Azure and is dedicated to your subscription.

A virtual network is a group of IP addresses linked together, which is an essential factor to contemplate when devising solutions in the cloud. To ensure that every layer of the application architecture is safeguarded within a reliable network, it is wise to form various subnets for the different levels of the application and attach each subnet to a network security group with limited inbound and outbound rules for security.

Scenario:
As a cloud and DevOps Engineer, I'm creating an Azure Virtual Network (Vnet) for a Tech Company using the address space 197.152.50.0/24. The network will be segmented into four subnets, each with a subnet size of /28 to ensure proper resource isolation and IP management.

STEP 1: Go to portal.azure.com
-search for 'Virtual network'

Click on 'create a virtual network'

STEP 2: On the Basics under Create virtual network tab

create a resource group
Give the Vnet a name
Indicate the region
Click on next to continue

STEP 3: Allow the default settings in the security tab

STEP 4: Click on IP Address tab

Type in the IP address
Click on the 'add a subnet button'

On the 'add subnet button'

Leave the subnet purpose at default
Give the subnet a name 'Finance'
Allow other settings at default Click on 'add' button

Click on the 'add subnet button' again

Give the subnet a name 'Operations'
Change the size to /28 The starting address will automatically change
Allow other settings at default
Then click on the 'Add' button

Click on the 'add subnet button' again

Give the subnet a name 'Sales'
Change the size to /28 The starting address will automatically change
Allow other settings at default
Then click on the 'Add' button

Click on the 'add subnet button' again

Give the subnet a name 'Transport'
Change the size to /28 The starting address will automatically change
Allow other settings at default
Then click on the 'Add' button

The four added subnets created were successfully added as shown below

Then click on 'Review and Create'
Then click on 'create'

Deployment id complete

Click on 'Go to resource'

My network overview page is displayed below

Go to setting on the left pane

click on 'subnet'

The available IPs that are available are shown below, azure reserves 5 IPs for other resources

AUTHENTICATION AND AUTHORIZATION

Iniobong Ema — Fri, 18 Apr 2025 08:16:18 +0000

AUTHENTICATION
Authentication is the process of establishing the identity of a person or service looking to access a resource. It involves the act of challenging a party for legitimate credentials, and provides the basis for creating a security principal for identity and access control use. It establishes if they are who they say they are.

AUTHORIZATION
Authorization is the process of establishing what level of access an authenticated person or service has. It specifies what data they're allowed to access and what they can do with it. Authentication is sometimes shortened to AuthN, and authorization is sometimes shortened to AuthZ. Azure provides services to manage both authentication and authorization through Azure Active Directory (now Microsoft Entra).

STEP 1: To create a new user, Go to portal.azure.com
- Search for Microsoft Entra ID and click it

scroll down and click on 'add user'

Under create new user

Input user principal name
