Akraino Edge Stack Use Cases: Tencent’s End User Story
Tars Microservice Framework
...
The following picture depicts Tars' architecture. Tars can be deployed in multiple environments, including bare metal, virtual machines as well as the container.
In terms of RPC protocol， RPC， Tars supports Tars, Protocol Buffer, TUP, SSL, HTTP1/2. The customers can select any RPC protocol based on the application's requirement.
Beyond RPC call, Tars supports multiple languages and microservice governance functions, including Service Register/Discovery, Load Balance, Area Perception, Flow Control, Set Mode, Tracing and so on.
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
- 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.
- Rewrite some functions(like scale-out, monitor and so on) to reduce CPU consumption.
- Orchestrate no-urgent functions(like monitor data calculation and so on) from edge to DC(or higher level edge). Reduce resource consumption.
