Your private network in the cloud
- Build a hybrid infrastructure that you control
- Bring your own IP addresses and DNS servers
- Secure your connections with an IPsec VPN or ExpressRoute
- Get granular control over traffic between subnets
- Create sophisticated network topologies using virtual appliances
- Get an isolated and highly-secure environment for your applications
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 in the same way as you would treat 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 favourite network virtual appliances—WAN optimisers, 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 are building apps.
Tap your network traffic
Mirror and share a deep copy of your in and outbound virtual network traffic. Take advantage of aggregation, packet collection and load balancing solutions by streaming traffic to a destination IP endpoint or an internal load balancer in the same Virtual Network, peered Virtual Network or Network Virtual Appliance that you can deploy from a growing list of Security, Network and Application performance management partners.
