In what types of scenarios does Azure Express Route differentiate from typical Azure commodity offering like Virtual Private Network for Virtual Machines?

Express Route is great for those scenarios where the customer needs an extremely high performance, high volume connection Azure or incredibly distributed network that includes Azure. Virtual Private Network can only go to max bandwidth of 200Mbps. Express Route is used in this scenario to bridge the gap of Azure VPN’s limitation. This creates stickiness on your customer and increases the Average Revenue Per User (ARPU) with additional cross selling opportunities.
