How To Provision And Deploy Virtual Network On Azure Portal

Overview

• A virtual network (Vnet) is a logical representation of the physical hardware like switches and routers that make up the infrastructure.
• An Azure Virtual Network (Vnet) is a network or an environment that can be used to run VMs and applications in the cloud.
• Azure Virtual Network makes it possible for Azure resources like VMs to communicate with each other securely over the Internet.
• In this case, where we are working with four subnets, all the subnets are housed in one Virtual Network which can also communicate with on-premise device

Advantages of Using Azure Virtual Network

Some of the major advantages of using Microsoft Azure Vnet are ;

• It provides an isolated environment for your application
• A subnet in a Vnet can access the public internet by default.
• We can easily direct traffic from resources
• It is a highly secure network
• It has high network connectivity

Components of Azure Virtual Network

Azure Networking components provide a wide range of functionalities that can help companies builds efficient cloud applications that meets their requirements.
The components are listed below

• Subnets
• Routing
• Network Security Group

Subnets

• Subnets let users segment the virtual network into one or more sub-networks
• These sub-networks can be separated logically, and each subnet consists of a server
• We can further divide a subnet into two types

1. Private, accessible anywhere within the internet
2. Public, accessible within your network

Assuming you were given an IP Address 192.148.30.0/26 to create four subnets.
Below step by step, the format will be of use

• Log in to Azure portal
• Search for a virtual network in the Azure search bar
• Click on Create to create a virtual network Create a Virtual Network

On the Basic Tab

• Under Project Details
• Make sure there is a subscription
• Create a resource group-Hagital_Cloud
• Or use the existing one
• Under the Instant Details
• Select the virtual network name-Hagital_vnet
• Choose the region that is close to you-(US)East US
• Click Next

On the IP Address Tab

• Input the given 4-octate IP Address
• Select other four departments (Marketing, Sales, Account and Finance)
• Select from the dropdown bar, the CIDR value
• Click on + Add a subnet

Add a Subnet

• Input the subnet for the choice departments
• Subnet purpose-Default
• Subnet name-Marketing
• Every other thing is left as default

Click + Add to Add Another Subnet

• Repeat the process again to create the remaining subsets with different address ranges from; **- (192.148.30.0/26) (192.148.30.64/26)
• (192.148.30.128/26)(192.148.30.192/26)**
• Click Review + Create
• Security tab and Tag are left as default

Create a Virtual Network

• Click on Create
• Deployment Completed
• Click on Go to the resource
• Click Overview to see the resource running
• Click on setting
• Click on the subnet to see the performance Remember, you can always create another subnet by clicking on the + subnet icon on the upper area
