Meeting Web Application Performance Service Level Requirements Head-on

EasyChair Preprint 3105

Abstract

Performance service level requirements are often included in web application development contracts and SLAs without much thought given to the measurements and analysis needed to demonstrate compliance with those requirements. Often specifications are so vague they lead to customer and vendor disagreeing over what data should be used to determine compliance or, agreeing on a data collection and analysis scheme that is inconsistent with fundamental statistical principles. This paper identifies the properties of a good web application performance specification and illustrates how compliance with that requirement can be demonstrated with a measurement mechanism which mirrors it as well as conforms to standard statistical inference methods.

Keyphrases: Computer performance, Service Level Agreement (SLA), Student's t-distribution, confidence interval, normal distribution, statistics
