As on the ground microservice practitioners quickly realize, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined distributed services versus a single monolithic application.
Envoy offers flexible pricing suitable for enterprises, with plans starting at an affordable rate for basic features. Enterprises find the pricing justifiable given the robust functionality and superior user experience. Custom pricing may be available for larger organizations requiring additional features and premium support. Feedback highlights that while the cost tends to rise with increased usage and advanced needs, the investment is perceived as worthwhile for the benefits provided.
Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures. Built on the learnings of solutions such as NGINX, HAProxy, hardware load balancers, and cloud load balancers, Envoy runs alongside every application and abstracts the network by providing common features in a platform-agnostic manner. When all service traffic in an infrastructure flows via an Envoy mesh, it becomes easy to visualize problem areas via consistent observability, tune overall performance, and add substrate features in a single place.
