What is Azure ExpressRoute?

Microsoft Azure ExpressRoute lets customers create private connections into the Microsoft cloud. With ExpressRoute, customers can establish connections to Microsoft Azure.

ExpressRoute connections don't go over the public Internet. They can offer more reliability, faster speeds, lower latencies, and higher security than typical Internet connections.

In some cases, using ExpressRoute connections to transfer data between on-premises systems and Azure can yield cost benefits.
