Varying Resource Consumption to Achieve Scalable Web Services
نویسندگان
چکیده
Web service deployment is hampered by the possibility of sudden variations in request volumes. Mechanisms exist to enhance scalability in times of heavy load when the delivered content is static. However, web services typically involve dynamic content, delivered through application servers which may have little to no support for adapting to varying loads in order to ensure timely delivery. In this paper we discuss why scaling dynamic content delivery under load is difficult, we present a technique for controlled service degradation to achieve this scalability, and we present experimental results evaluating its benefits.
