Microsoft yesterday announced the general availability of Azure routing preference, a new option that will allow Azure customers to choose how their traffic routes between Azure and the Internet. Customers can route traffic either via the Microsoft network, or, via the public internet provided by the ISP network.
Routing via Microsoft global network will deliver traffic over a reliable private global network while the routing via ISP network gives you a cost optimized choice. Microsoft also mentioned that routing via Microsoft’s network provides the best latency. You can read about the supported Azure services below.
