Unlike traditional architectures that rely on virtual machines for routing, virtual network routing appliance runs on specialized networking hardware to deliver low latency and high throughput for your traffic flows.
+Azure Virtual Network routing appliance is a high-performance solution that provides a managed, scalable forwarding layer for your virtual networks. Virtual network routing appliance runs on specialized networking hardware to deliver low latency and high throughput for your traffic flows.
 
 As a top-level Azure resource, virtual network routing appliance integrates with Azure's management model, so you can deploy, configure, and govern it using familiar Azure tools and processes. You deploy the appliance in a dedicated subnet within your virtual network, where it acts as a high-bandwidth forwarding layer for routed traffic.
