When does one choose Express route over VPN for Azure connectivity?

A Virtual Private Network (VPN) has a maximum throughput of 200 Mbps in its highest offering. If data bandwidth needs are over and above this limitation, then it can be one reason to choose Express Route. An Express Route has a more committed performance as it’s based on a private carrier while VPN rides over the internet traffic. Also, express route support bandwidth up to 10 Gbps.
