基于微服务的数据服务框架设计

A data service framework based on microservices

为了克服传统数据服务平台协议复杂、体量庞大,在扩展性和易维护性方面都存在的不足,提出了一种基于微服务的数据服务框架.框架分离了微服务容器和服务源,采用轻量级的跨平台协议,在容器中通过两种类型(原生型和代理型)的微服务与服务源中的微服务连接起来,达到解耦合、去中心化和服务泛在的目的.此外还分析了框架的重要特征,阐述了技术方案中的若干要点.北京大学的实践表明:基于该框架建设的数据服务平台,易于扩展、便于运行维护,可以实现更加灵活的数据共享.

Traditional data services platform is complex,large volume,and it is lack of scalability and ease of maintenance.A data services framework based on micro-services is presented in this paper.It separates the micro-services container and services sources,uses lightweight cross-platform protocols,bridges the micro-services container and services sources with two types of micro-services:native micro-services and proxy micro-services,to achieve the purposes of decoupling,decentralizing and services being ubiquitous.This paper also analyzes the important features of the framework,and describes a number of key elements in the framework technical solutions.By the practice of Peking University,a data services platform based on this framework is implemented,a more scalable,ease of operation and maintenance,and more flexible data sharing is achieved.
