随着目前网络访问量和数据流量的不断增加,现有各个核心部分业务量的快速增长,对服务器处理能力和计算强度也提出更高的要求。这也使单一的服务器设备根本无法承担。因此,研究者开始安装利用集群服务器,最大程度的实现群集化资源的可用性,减少单点故障数量。主要介绍服务器集群和负载均衡,并对负载均衡的计算方法进行研究。 With the current network traffic and data traffic continues to increase, the existing core business volume of the rapid growth of server processing power and computational intensity also put forward higher requirements. This also makes a single server device simply can not afford. As a result, researchers began installing and utilizing cluster servers to maximize the availability of clustered resources and reduce the number of single points of failure. Mainly introduces server cluster and load balancing, and studies the load balancing method.
