In November we released Envoy Mobile v0.2. In the accompanying blog post we detailed the features that the library supported and announced that we had replaced the networking libraries in Lyft’s alpha rider app with Envoy Mobile. In this blog post, I want to expand on the technical aspects of the v0.2 release and take a technical deep dive of Envoy Mobile’s current architecture.
