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.
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.
Multiple clouds and private datacenters with dynamic IPs, ephemeral containers, dominated by east-west traffic, no clear network perimeters.
-Centralized registry to locate any service
-Services discovered and connected with centralized policies
-Network automated in service of applications
-Zero trust network enforced by identity-based security policies
Envoy is ranked 5th in Service Mesh while HashiCorp Consul is ranked 4th in Service Mesh. Envoy is rated 0.0, while HashiCorp Consul is rated 0.0. On the other hand, Envoy is most compared with Kong Kuma, VMware Tanzu Service Mesh and AWS App Mesh, whereas HashiCorp Consul is most compared with AWS App Mesh, Kong Kuma, VMware Tanzu Service Mesh and Buoyant Linkerd.
