Website Migration Load Balancing of Web Servers

Many web hosting companies do not load balance their web servers. The reason is that current web server load balancing techniques are expensive. Website migration is a costeffective and simple load balancing solution for web hosting companies that host web sites whose load is small in comparison the capacity of a web server. The main objectives of website migration is to reduce the average latency and the variance in latency. The major costs, associated with website migration, are: interrupted service, increased load on the web servers and the web server cluster’s network, and redirection. A major difficultly with website migration, as with any web server load balancing scheme, is that load is inherently multi-dimensional, whereas good multi-dimensional load balancing algorithms are hard to find. Our preliminary experimental results show that website migration is a promising approach for load balancing of web servers hosting small websites.
