Azure Virtual Network service allows you to create controllable hybrid infrastructure, IP addresses and DNS servers. Microsoft Azure Virtual Network service offers a secure environment for your connections via an IPsec VPN and ExpressRoute, as well as granular control over traffic between subnets. It also creates complex network topologies with virtual appliances, and provides an isolated and highly secure environment to applications. Azure Virtual Networks services can be used worldwide to provide beneficial solutions for many top companies and organisations.
In this blog, however, we will be learning how to create and maintain virtual networks. Before we proceed, let’s first take a look at Azure Virtual Network.
What is the Azure Virtual Network?
Azure Virtual Network (VNet), can be considered a basic building block of your private network in Azure. VNet allows you to access many Azure resources, such as Azure Virtual Machines (VM), for securely communicating with each another, the internet, or on-premises networks. This is the traditional network, but VNet can be managed in its own datacenter. It also has the additional benefits of Azure infrastructure such as scale, availability, isolation.
Also, Azure Virtual Network features include:
1. Security and isolation enhancement
Azure Virtual Network offers a secure remote environment to run virtual machines and applications. Virtual Network allows you to treat Azure the same way that you would treat your datacenter.
2. Rely on our global reach
Virtual Network allows traffic to be carried between Azure resources in one region or multiple regions. Traffic for Azure virtual machine-tovirtual machine, storage and SQL communication only flows through the Azure network. Traffic from inter-regional virtual networks to virtual networks flows completely through the Azure network.
3. Create sophisticated network topologies
You can run your network virtual appliances such as load balancers, WAN optimizers, and application firewalls in a virtual network. You can also specify traffic flows to give you greater control over your network design.
4. Expand your datacenter to the cloud
Virtual Network allows you to expand your on-premises IT environment and connect to a remote branch office. This allows you to securely connect to a virtual network by selecting an IPsec VPN or private connection using Azure ExpressRoute.
5. Develop hybrid applications
Virtual Network allows you to create hybrid cloud applications that securely connect with your on-premises datacenter. This allows an Azure web app to access a SQL Server database. It can also authenticate customers against an Azure Active Directory service.
6. IaaS and PaaS are better together
Virtual Network allows you to create services that are dependent on Azure cloud services or Azure Virtual Machines. Azure Virtual Network allows you to use Azure web roles on your front end and virtual machine backend databases. You can also integrate platform as an service (PaaS), infrastructure as a Service (IaaS), in a virtual network to increase flexibility and scalability when creating apps.
We have already covered the basics of Azure Virtual Network. Next, we will discuss how to manage virtual in Azure.
Get started with Azure Virtual Networks
1. Azure portal: Creating a virtual network
This article will show you how to create a virtual network with the Azure portal. We will use the Azure portal to deploy two virtual machines (VMs), and then securely communicate between them and connect to them from the internet.
1. Create a virtual network
First, click in the upper left corner of the portal and select Create a Resource.
Second, you can enter Virtual Network
