Scalability of a Parallel Application in Hybrid Cloud

Abstract

Cloud computing is a convenient, on demand, model which relies on shared pool of computing resources that can be rapidly provisioned and needs minimal management effort. As cloud computing obtains popularity nowadays, customers are looking for cloud solutions to adapt their organization's requirements. The more changes occur, customers are trying to decide what kind of cloud they are going to choose. Beside that, users are concerned about security, privacy, vendor lock-in and cost issues. A hybrid cloud is a mix of one private cloud and at least one public cloud, customers could benefit interoperability and flexibility. There are many elements that should be considered in hybrid cloud architecture. This paper represents a set of mpi benchmarking test executed on a private and public cloud environment in order to evaluate the QoS when real application is running.
