Customers running Virtual Network
Enhance security and isolation
Azure Virtual Network gives you an isolated and highly-secure environment to run your virtual machines and applications. Use your private IP addresses and define subnets, access control policies, and more. Use Virtual Network to treat Azure the same as you would your own datacenter.
Rely on our global reach
Traffic between Azure resources in a single region, or in multiple regions, stays in the Azure network—intra-Azure traffic doesn’t flow over the Internet. In Azure, traffic for virtual machine-to-virtual machine, storage, and SQL communication only traverses the Azure network, regardless of the source and destination Azure region. Inter-region virtual network-to-virtual network traffic also flows entirely across the Azure network.
Build sophisticated network topologies
In a virtual network, run your favorite network virtual appliances—WAN optimizers, load balancers, and application firewalls—and define traffic flows, allowing you to design your network with a greater degree of control.
Extend your datacenter into the cloud
Use Virtual Network to extend your on-premises IT environment into the cloud, like you set up and connect to a remote branch office. You have options to securely connect to a virtual network—choose an IPsec VPN or a private connection by using Azure ExpressRoute.
Create hybrid applications
Use Virtual Network to build your hybrid cloud applications that securely connect to your on-premises datacenter—so an Azure web application can access an on-premises SQL Server database, or authenticate customers against an on-premises Azure Active Directory service.
IaaS and PaaS, better together
Use Virtual Network to build your services that rely on Azure cloud services and Azure Virtual Machines. Use Azure web roles for your front end and virtual machines for backend databases. Combine platform as a service (PaaS) and infrastructure as a service (IaaS) in a virtual network to get more flexibility and scalability when you’re building apps.
