A Multi-Cloud Framework for Measuring and Describing Performance Aspects of Cloud Services Across Different Application Types

Cloud services have emerged as an innovative IT provisioning model in the recent years. However, after their usage severe considerations have emerged with regard to their varying performance due to multitenancy and resource sharing issues. These issues make it very difficult to provide any kind of performance estimation during application design or deployment time. The aim of this paper is to present a mechanism and process for measuring the performance of various cloud services and describing this information in machine understandable format. The framework is responsible for organizing the execution and can support multiple cloud providers. Furthermore we present approaches for measuring service performance with the usage of specialized metrics for ranking the services according to a weighted combination of cost, performance and workload.
