Abstract

The growing number of Cloud Infrastructure-as-a-Service (IaaS) offerings today leave a wide range of choices when deploying an application in the Cloud. Self-configuring and -optimizing autonomic systems have to select an infrastructure which fits the performance preferences while simultaneously offering the optimal performance per price ratio. A task which is not trivial. Indicators provided by providers are often not coherent and not sufficient to predict the actual performance of a deployed application and, thus, raise the need for benchmarking the offered services. This implies, however, intensive effort to gather the needed metrics, growing with every additional provider taken into consideration. In this paper we present an approach based on the theory of optimal stopping that enables an automated search for an optimal infrastructure service regarding performance-per-price-ratio while reducing costs for benchmarking.
