> May I ask what one might use in an AWS cloud environment to provide that load balancer within a Region?

The AWS cloud controller will automatically set up an ALB for you if you configure a LoadBalancer service in Kubernetes. I've also done custom setups with AWS NLBs.

It could address some issues- you could conceivably create a CNI plugin which allocates an externally addressable IP to your Pods. Although you would probably still want a load balancer for custom routing rules and the improved reliability over DNS round robin.

Are ALB/NLB employed to handle traffic between pods in the same cluster? Or have I misunderstood the whole discussion?

My take on the 'eBPF will help solve service mesh' proposal is that it deals with not only ingress/egress traffic (where ALB/NLB are typically employed) but all traffic, including traffic between pods in a cluster. This is where my interests lay.

You can choose to do so, or you can communicate directly via the built-in Kubernetes service discovery and CNI overlay network. There are use cases for both.
