Low-latency service grid solution Kmesh released
In April 2023, Kmesh, a new project hatched by openEuler, was officially released. This project provides a low-latency data plane solution for service grids and supports high-performance load balancing, routing, and grayscale capabilities. Due to its sidecar proxy architecture, the traditional service grid has problems of high latency and high resource overhead. How to provide a low-latency service grid solution has become a challenge for the industry. The kmesh project is based on a programmable kernel, and completes follow-up governance in the OS, so that service access in the grid changes from 3 hops to 1 hop, and the performance is improved by 5 times. If you are interested in a high-performance service mesh, the Kmesh project is a choice you should not miss.
