Optimal Processing Policies for an e-Commerce Web Server

Yong Tan, Kamran Moinzadeh, Vijay S. Mookerjee
2005 INFORMS journal on computing  
Thus, the processing policy of the server evolves from an emphasis on QoS in initial periods, to one on profit in subsequent periods.  ...  In the multiperiod problem, both the server capacity and the processing policy in each period are determined optimally.  ...  Acknowledgments The authors thank the Area Editor (Ramayya Krishnan), the Associate Editor, and the two anonymous reviewers for their valuable comments and suggestions.  ...

Accelerating Database Processing at e-Commerce Sites [chapter]

Seunglak Choi, Jinwon Lee, Su Myeon Kim, Junehwa Song, Yoon-Joon Lee
2004 Lecture Notes in Computer Science  
Most e-commerce Web sites dynamically generate their contents through a three-tier server architecture composed of a Web server, an application server, and a database server.  ...  WDBAccel eliminates costly, complex query processing needed to obtain query results by reusing previous query results for subsequent queries.  ...  In most e-commerce Web sites, those services are usually deployed on a three-tier server architecture, which consists of Web servers, application servers, and database servers.  ...
