Dependability Benchmarking of Web-Servers

Authors

Abstract

This chapter presents a dependability benchmark for web-servers. Our benchmark is composed of the three key components: measures, workload, and faultload. We use the SPEC-Web99 benchmark as starting point, adopting the workload and performance measures from this performance benchmark, and we added the faultload and new measures related to dependability. We illustrate the use of the proposed benchmark through a case-study involving two widely used web servers running on top of three different operating systems. The faultloads used in our case-study encompass software faults, hardware faults and network faults. We show that by using the proposed dependability benchmark it is possible to observe clear differences regarding dependability properties of the web-servers.
