Today we are thrilled to announce the initial OSS preview release of Envoy Mobile, an iOS and Android client network library that brings the power of Envoy Proxy to mobile platforms. This is the beginning of a journey that we hope mobile developers around the industry will join us on. When Lyft originally announced Envoy in 2016, the project goal was simply stated as: The network should be transparent to applications. When network and application problems do occur, it should be easy to determine the source of theproblem. Envoy proxy was initially built at Lyft to solve the networking and observability issues inherent in large polyglot server-side microservice architectures. Over the last two and a half years, much to our surprise and satisfaction, Envoy has become incredibly popular throughout the industry. Today Envoy is used by all major public cloud providers, countless end user companies, and a plethora of infrastructure startups that have recognized Envoy’s extensibility as a useful base with which to build vertical applications and services. For those not familiar with Envoy’s architecture and feature set, please see the links in the further reading section at the bottom of this post.
