<p>A single Internet application can invoke many different Web services ? for example, the metasearch engine WebSifter uses several online ontologies to refine a user?s request into a more meaningful query and then submits that query to various search engines in parallel. We call such applications composite Web services. As I discussed in a previous column, many important challenges stem from the quality-of-service issues in composite Web services. In this column, I address the impact of slow services on the overall response time of a transaction that uses several Web services in parallel.</p>
