Introduction

Kmesh is a high-performance and low overhead service mesh data plane based on eBPF and programmable kernel. Kmesh brings traffic management, security and monitoring to service communication without needing application code changes. It is natively sidecarless, zero intrusion and without adding any resource cost to application container.

Why Kmesh

Challenges of the Service Mesh Data Plane

Service mesh software represented by Istio has gradually become popular and become an important component of cloud native infrastructure. However, there are still some challenges faced:

Kmesh Architecture

Kmesh transparently intercept and forward traffic based on node local eBPF without introducing extra connection hops, both the latency and resource overhead are negligible.

Kmesh Architecture

The main components of Kmesh include:

Kmesh innovatively sinks Layer 4 and Simple Layer 7 (HTTP) traffic governance to the kernel, and build a transparent sidecarless service mesh without passing through the proxy layer on the data path.

Simple Mode

Kmesh also provide an advanced mode, which makes use of eBPF and waypoint to process L4 and L7 traffic separately, thus allow you to adopt Kmesh incrementally, enabling a smooth transition from no mesh, to a secure L4, to full L7 processing.
