Azure VNet has many benefits and capabilities. The following benefits are some of them:

• Isolation: Each virtual network is isolated from other virtual networks. Therefore, you can have your dev/test environment in a virtual network separated from the production environment that exits in other virtual networks.
• Communicating with other VNets: By default, virtual networks are isolated from each other. However, you can reach out resources in another virtual network, because virtual networks can be connected to each other.
• Broad network access: By default, all Azure services have access to the internet, which means you can access Azure services from wherever you want, using whatever you want, as long you have an internet connection.
• Hybrid connectivity: Azure VNet can be spanned to your data center. As a result, you will be able to connect to both your Azure resources and on-premises resources privately without the need to connect via the internet.
• Security: You can secure your virtual networks by setting rules that determine which inbound and outbound traffic can be flowed to and outside the virtual network.
