Question

A financial services company has two on-premises datacenters, one in London and one in Singapore, each connected to Azure via a dedicated ExpressRoute circuit terminating in the nearest Azure region. A new regulatory requirement mandates that the London and Singapore datacenters exchange data directly over a private, high-throughput connection that does not traverse the public internet, and that traffic between the two sites should use the Microsoft global backbone. Which solution should the architect recommend?

Accepted Answer

Enable ExpressRoute Global Reach to link the two ExpressRoute circuits, allowing the on-premises datacenters to exchange traffic over the Microsoft backbone.

Answer

Deploy a site-to-site VPN between the two on-premises datacenters over the public internet with IPsec encryption.

Answer

Create a hub-and-spoke topology with virtual network peering between the London and Singapore Azure regions and route on-premises traffic through the hub VNets.

Answer

Configure ExpressRoute FastPath on both circuits to bypass the virtual network gateway and reduce latency between the datacenters.
