I've spent some time helping organisations move their DNS infrastructure from legacy on-premises Active Directory (AD) DNS to modern hybrid cloud environments. They're all different, but they all share some common threads.

If you're planning to migrate to a hybrid cloud environment, it's common to think about connectivity first: ExpressRoute, Direct Connect, VPN, SD-WAN, and so on. But DNS should be top of the list. It's the foundation of your network. If your DNS isn't designed for hybrid, it doesn't matter how good your connectivity is. Your applications won't be able to find each other, and your users won't be able to access services.

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. The platform give an easy to manage low cost NVA which can be scaled out to cloud spokes to give consistent egress policy. As HA (High Availability) is crucial for any production environment, I wanted to investigate how easy it was to combine more than one enforza instance to achieve a highly available egress solution.
