Tencent has been deploying Tars on Connected Vehicle Blueprint and validating on IEC Type 4: AR/VR oriented Edge Stack for Integrated Edge Cloud (IEC) Blueprint Family.

Tars Microservice Framework

Tars Optimization for edge

To address the requirements of time-critical Application on the edge, some optimizations are itemized below:

  • High-Performance RPC:   Tars Framework supports a high-performance RPC Protocol, called Tars Protocol.   To improve the performance, the Tars protocol re-design a brand new RPC protocol and make the transfer between "request" and "Binary stream" more efficiently. In terms of the detail of Tars protocol, refer to the Tars.h file in the https://github.com/TarsCloud/Tars. 
  • Lightweight framework
    1. To make Tars can be well deployed on the edge computing platform, we make the framework pluggable. The customer plugin the pluggable components when we really need it. Unnecessary components can be avoided.
    2. Rewrite some functions(like scale-out, monitor and so on) to reduce CPU consumption. 
    3. Orchestrate no-urgent functions(like monitor data calculation and so on) from edge to DC(or higher level edge). Reduce resource consumption.

For more detail information for Tars, refer to https://github.com/TarsCloud/Tars/blob/master/Introduction.md.

  • Xin Liu, General Manager of Future Network Lab, Tencent

“Tencent has been ready for open source and joined the Linux Foundation to become a platinum member. Tencent also donated TARS to Linux Foundation, a multilingual microservice development framework that has been used for ten years. Tars has been a mature project in Linux Foundation , and is currently providing mature infrastructure for projects in LF Edge. At present, tars TARS has become the unique microservice development framework in the connected vehicle and AR / VR blueprint of Akraino, improving the necessary conditions for high availability, high performance, and service governance of applications. We will continue to develop the TARS project and Akraino project in edge computing. Tencent will establish an open-source foundation with more partners and contribute more projects to the open-source industry in the future. Welcome to join us! ”
