Reconstruction And Optimization Of OJ System Based On Micro-service

With the increasing scale,complexity and scalability requirements of software system in the field of web development,the limitations of the old monolithic architecture model,such as the inability to achieve high-performance and high scalability,began to emerge.At the same time,the corresponding micro-service architecture started to work.When facing with the increasing complexity and expansibility of system,it's definitely a better choice for us to use micro-service architecture.Based on the school online programming system,this paper first discussed the shortcomings of the existing system and compared the original monolithic architecture with the current micro-service architecture.And then,micro-service architecture is adopted for system reconstruction.In addition,this paper proposed some improvements:Redis is used as centralized cache for some hot data,which is also separated out as independent cache services for other micro-service calls,and it also avoid unnecessary database query.In this way,it not only reduce the database pressure,but also improve the speed of data query;When it comes to deployment of website,we used nginx to realize front-end load balancing,and improve the concurrency of website;Furthermore,we also studied and provided a perfect micro-service system monitoring program to make up for the deficiency of previous system in the aspect of system monitoring;Finally,we realize the distribute deployment of micro-service using Docker.From the optimization scheme mentioned above,it can be seen in the final performance testing results that the reconstructed system has better performance.From the back-end micro-service distributed deployment point of view,the scalability of system improved significantly.At the same time,the monitoring of each micro-service can be achieved.
