Dynamic resource management for longevity in web server systems seok-bong choi

As the Internet became a popular source of information, more and more people are using the Internet in their everyday life. Therefore, for the servers that maintain web page sites get a lot of transactions and to maintain a stable environment, a lot of web sites have more than one server for these transaction requests. a common architecture to balance the transactional load is by using a L7 switch to distribute the requests. The current L7 switch utilizes methods that cannot sustain the web site for long if there are dynamic interactive pages. There have been researches to load balance web sites for static web pages. However, as more and more web pages become dynamic and interactive, there needed to be a method that prolongs the web site crashes without buying large number of servers. Our methods use explicit CPU utilization information to dynamically decide which transactional request is mapped where. Using our methods, the longevity (the length of the web site remains open) of a website is higher than other researched/utilized methods.
