Aruba virtual gateways are deployed in public cloud infrastructure such as Microsoft Azure.  Aruba Virtual Gateways for Azure are managed by Aruba Central, a cloud-based management system, to connect branch and headend data center locations seamlessly to business applications that reside within an Azure Virtual Network (VNET). Virtual gateways support both public Internet and private connections such as ExpressRoute. Aruba SD-WAN greatly enhances the use of public clouds by making it easy to connect to virtual private cloud instances. This optimizes the networking of the hosted workloads by providing complete lifecycle management and orchestration of connectivity policies.

Virtual Gateways are available in 1, 3 or 5 year subscription license options - and do not require additional software usage costs in Azure. Virtual Gateways are available in 500 Mbps, 2Gbps and 4 Gbps of throughput licenses.
