Several medium to large companies are currently in the process of using external hosting to deploy their internet applications. External hosting by such application service providers (ASPs) as IBM provides a secure and reliable way for companies to deploy e- commerce enterprise applications without the need to purchase costly infrastructure. However, when software is designed for applications that run on the servers of external hosts, the performance may suffer if the data and the application reside at two different locations. The authors provide a technique for improving the performance in such applications. This technique is implemented in large software systems that the authors are associated with as industry consultants. The software architecture and preliminary performance results are provided.
