You comment kicked off a big internal chat, which led to someone creating a document on our overlay approach, vs service meshes. I took that, wrote some extra details, comparison and summary - https://docs.google.com/document/d/1ih-kuRvfiGrJODZ5zVjwFLC2....

TL:DR, we believe service meshes introduce complexity with control plane synchronization, service discovery challenges, and network overlays. A Global Overlay removes Kubernetes service dependencies and shifting networking to a Zero Trust, software-defined global overlay which is much simpler, automated and secure.

Super curious to get your thoughts.
