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
- Private, accessible anywhere within the internet
- 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
