Mesher

A service mesh implementation based on go chassis.

Why use mesher

• any infrastructure: if you use ServiceComb as control plane, you can run on any infrastructure(docker, kubernetes,VM, bare metal).
• service mesh and frameworks: you can develop micro services with java chassis or go chassis frameworks and use mesher to make other service join to the same system.
• flexible: you can develop and customize your own service mesh
• OS: support both linux and windows OS, which means you can govern your services writen in .net with java, go etc.
• API gateway: mesher is able to run as a independent edge service and manage ingress traffic.

Features

• Build on top of go micro service framework: so that mesher has all of features of go chassis,a high flexible go micro service framework. you can custom your own service mesh and API gateway by extending lots of components.
• Admin API：Listen on an isolated port, expose useful runtime information and metrics.
• support protocols: http and grpc
• No IP tables forwarding: Mesher leverage http_proxy and grpc proxy dialer, that makes better performance than using ip tables
• local health check: as a sidecar, mesher is able to check local service health by policy and dynamically remove it from service registry if service is unavailable.

in future

• support skywalking
