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.

Most people think of Azure Public Load Balancer as that thing that spreads web traffic across multiple servers. Fair enough - that's what it does best. But it's actually a Swiss Army knife for network address translation that can solve some tricky connectivity problems you might not expect.

Let's explore solutions for global site load balancing.

I recently went down the AWS Gateway Load Balancer rabbit hole, and I've found it to be an interesting solution to some quite specific problems. There are use cases for it on ingress and egress where regulatory requirements, or more likely legacy skillsets, dictate that traffic passes through NVA-based network security appliances. The problem with NVAs in AWS is often the difficulty in scaling them. You need to distribute traffic, and typically you need a load balancer, but you can't use an ALB or an NLB because unlike Azure, the load balancers in AWS don't allow for traffic routing, so they can't be targets for route tables in the same way Azure load balancers can be targets for UDRs.
