Service Mesh Startup Tetrate Aims to Bring Enterprise Scalability to Istio, Envoy: In a surprise announcement at the event, we learned of a set of service mesh technologies from a new startup called Tetrate, founded by now-CEO Varun Talwar, who created the popular service mesh Istio at Google. It will be a while before we see the bits, but at least the newfound company has released some open source utilities — including GetEnvoy, Apache SkyWalking, and the Tetrate Istio Cloud Map Operator.
