Azure Virtual Networks Can Be Created Using

What are Azure Virtual Networks?

Azure Virtual Networks (VNETs) are software-defined networks within the Microsoft Azure cloud platform that enable users to connect and isolate their Azure resources securely. With VNETs, you can create private network environments similar to traditional on-premises data centres but with the added scalability and flexibility of cloud computing. Azure VNETs play a crucial role in establishing reliable communication between resources and controlling network traffic, ensuring the secure transmission of data.


By creating an Azure VNET, you can segment your resources, effectively organizing and categorizing them according to your infrastructure requirements. This segmentation is achieved by creating one or more subnets within a VNET. Each subnet acts as an independent network segment with its own set of IP addresses, access controls, and other settings. This segmentation enables you to achieve greater control and increased security by isolating specific resources from others.


Azure VNETs enable seamless communication between virtual machines, cloud services, and other resources within the Azure environment. This network infrastructure supports various traffic types, including inbound and outbound traffic, providing users maximum control over network traffic flow. Additionally, Azure VNETs are highly scalable, allowing users to dynamically adjust and adapt to changing business needs.

Benefits of Azure Virtual Networks

Before diving into the creation process, it is essential to understand the key benefits of Azure Virtual Networks. These benefits include:

  • Isolation and Security: Azure Virtual Networks provide a secure resource environment, allowing you to control inbound and outbound traffic through network security groups and virtual network firewalls.
  • Scalability: With Azure VNETs, you can quickly scale your Network by adding or removing subnets and virtual machines as your requirements evolve.
  • Connectivity Options: Azure VNETs offer various connectivity options, such as VPN Gateway for secure connections with on-premises networks and Azure ExpressRoute for private network connections.
  • Network Segmentation: You can divide your Azure resources into multiple subnets within a virtual network to facilitate better organization and segmentation of your infrastructure.
  • Global Reach: Azure VNETs provide global reach, enabling you to connect resources across different regions and even Azure subscriptions.
