Today we’re announcing the preview of the new ability to deploy and run third-party Network Virtual Appliances such as SD-WAN natively within the Azure Virtual WAN hubs.

As enterprises increasingly adopt the cloud while reducing their costs, IT teams looking to consolidate, accelerate, or even revamp connectivity models should consider Azure Virtual WAN. Modern enterprises require ubiquitous connectivity between hyper-distributed applications, data, and users across the cloud and on-premises.

Since we announced automated and integrated transit capabilities with Azure Virtual WAN as the first in the public cloud back in 2018, the interest to take advantage of Azure when building or re-architecting branch networks for the cloud has grown fast.

Azure Virtual WAN provides a service architecture to take full advantage of Microsoft’s fast global network. Virtual WAN makes it easy to connect Virtual Networks (VNets), Azure ExpressRoute, VPN, and now SD-WAN in “virtual hubs.” The connectivity agnostic approach allows full transit between branches, sites, mobile users, and services using Azure’s global infrastructure.

Networking trends, typically led by an Internet-first approach, are increasingly leveraging technologies such as SD-WAN to improve performance through intelligent path selection and central policies. They work to eliminate traditional networking backhauls by sending traffic directly from branch to the cloud via local breakouts and allows you to leverage your chosen vendor’s path selection and policy management.

Whether you are looking to simplify interconnectivity between internet (VPN) and private (ExpressRoute) users and sites or considering large scale branch/SD-WAN architectures, using Azure Virtual WAN can be the foundation of your solution. The new virtual appliance-in-hub capability will start rolling out to select Azure regions July 20, 2020.  

“Azure Virtual WAN can now be the central network hub for all our traffic and a key pillar in our cloud strategy,” said Leon Sevriens, IT Manager, at Humankind, a large organization in the Netherlands that offers daycare and after-school care, with over 3,000 employees and over 450 locations. “The combination of Virtual WAN and Barracuda CloudGen WAN will give us the ability to test a resilient and modern cloud-native network with the performance and security we need for productivity tools, applications and data in the cloud.”


More capabilities now generally available

In addition to SD-WAN integration, we’re happy to announce the general availability of hub-to-hub connectivity, custom routing, Firewall Manager, and several other connectivity capabilities in Azure Virtual WAN.
