高并发访问下的分布式系统架构设计

Design of distributed system architecture under high concurrent access

随着网络应用的普及,由网络客户端对服务器端的高并发访问已经成为常态现象。现有分布式系统架构着重于客户端访问量与服务器端并行处理间负载均衡的策略设计。高并发访问带来的数据过热现象,很容易影响分布式服务器处理能力的稳定性。基于系统稳定性的考虑,文章设计了一种高并发访问下的分布式系统结构。该架构通过接入层分离应用层中客户端的读、写访问,并在计算层中搭建对应读、写访问的主、从服务器的分离处理构件,从而提升高并发访问下分布式系统的稳定性。

With the popularization of network applications,high concurrent access from network clients to servers has become a normal phenomenon.The existing distributed system architecture focuses on the strategy design of load balancing between client-side traffic and server-side parallel processing.However,data overheating caused by high concurrent access can easily affect the stability of the processing capability of the distributed server.Based on the consideration of system stability,the paper designs a distributed system structure with high concurrent access.The architecture separates the read and write access of the client in the application layer through the access layer,and builds the separate processing components of the master and slave servers corresponding to the read and write access in the computing layer,thereby improving the stability of the distributed system under high concurrent access.
