Universidade de Fortaleza, Fortaleza, Brazil

University of Fortaleza (UNIFOR) developed an app for performance assessment of workloads over applications running on IaaS cloud providers, called "CloudCapacitor". It is a novel approach to support application capacity planning in infrastructure-as-a-service (IaaS) clouds. CloudCapacitor relies on the assumption that there exists a capacity relation between different resource configurations offered by a given IaaS cloud provider, enabling one to predict (or “infer”), with high accuracy, an application’s expected performance for certain resource configurations and workloads, based upon its observed performance for other resource configurations and workloads in that same provider.

Preliminary empirical results, obtained from evaluating the performance of a well-known blogging application (WordPress) in a public cloud provider (Amazon EC2), show that the proposed approach can significantly reduce (over 85%) the total number of application deployment scenarios that need to be effectively tested in the cloud.

UNIFOR has been offering, since 1973, the best conditions for teaching and learning. With qualified professors, a modern infrastructure and incentives for research and post-graduation studies, all packed into an institution which maintains an excellent exchange program.

"I will present our research on doing performance evaluation and capacity planning on IaaS cloud applications. We have implemented some prototyping tools that enable a user to select what are the best cloud resources to run his application with high accuracy and low costs. We believe that our approach can be highly valuable for the cloud computing community as it tackles a quite challenging and relevant challenge." by Americo Sampaio
