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