多重负载均衡及网状环网的云平台的设计

The Design of Multiple Load Balancing and Network Ring Network Cloud Platform

随社会不断发展,人们对网页服务的需求也迅速提高,因此提供一个针对网页服务的、高可靠、高并发、高负载的云平台是势在必行的事。但现在不少的云平台都是由非常昂贵的设备(如小型机、中型机、大型机甚至巨型机)而构成,并且如果遇到不可避免的升级,就要抛弃现有设备去升级云平台,势必造成巨大的浪费,因此设计了一个服务器集群的云平台,该云平台的数据库服务器的集群在网状网中实现,通过多条链路与环上的ICX数据库服务器连接,网页服务器集群可以通过ICX数据库服务器或者环网访问数据库服务器,使云的可靠性大大增加,而且无论是数据库服务器集群,还是网页服务器集群都采用了多重负载均衡,特别在网页服务器集群的负载均衡,使用特定浏览器,使得云的性能得到很大的提高。

With the continuous development of the society, the demands on web service are also rapidly increasing. So providing a Cloud Platform with high reliability, high concurrency and high load is imperative. But there are many Cloud Platforms are formed with expensive equipments such as small, midrange, mainframe or even supercomputers. What is worse is that if it must be upgraded, all the related equipments must be abandoned which may cause huge waste. So a server cluster Cloud Platform should be designed, which have database server clusters in the network ring network, and those clusters connected to the ICX database servers can deliver information to the ring network through the multi - link. Outside the ring network, web server clusters can connect to database server clusters through one or more ICX database servers, all that mentioned above could make the reliability of this Cloud Platform increase greatly. Further- more, both the database server cluster and the web server clusters use multiple load balancing, especially in the web server clusters＇ multiple load balancing. Besides these, a specific browser is applied. These measures can surely improve the performance of the Cloud Platform greatly.
