Azure Global Load Balancer is often overlooked in favour of Azure Traffic Manager when it comes to global load balancing. Both are very capable options if all you want is to distribute traffic across multiple regions. However, Azure Global Load Balancer has a few tricks up its sleeve that make it a more interesting choice in some scenarios. The main one is that it uses Anycast for its frontend IP addresses.
I have been playing around with enforza.io for a while and it's a great solution for low cost internet egress across AWS and Azure.
