MOSN Project

MOSN, the short name of Modular Observable Smart Network, is a powerful proxy acting as Service Mesh's data plane like Envoy but written in GoLang. MOSN supports Envoy and Istio's APIs and can be integrated with Istio, so we use MOSN instead of Envoy in SOFAMesh. The initial version of MOSN was jointly contributed by Ant Financial and UC Business Unit of Alibaba, and we look forward to the community to participate in the follow-up development and build an open source excellent project together.

Develop States

After our efforts, MOSN’s 0.4.0 version has achieved a lot of improvement on performance and stability, we expect to release 0.5.0 version at the end of May 2019, which will be an stable version used in AntFin’s production environment. Before that, we will release the latest version named 0.4.x at the end of every month to synchronize the changes from March 2019.

Thanks

Thanks to Google, IBM, Lyft for creating the Envoy and Istio system, so that MOSN has a very good reference and we can quickly land our own ideas.
