Alexandru Iosup
Alexandru Iosup received his Ph.D. in Computer Science in 2009 from the Delft University of Technology (TU Delft), the Netherlands. He is currently an Assistant Professor with the Parallel and Distributed Systems Group at TU Delft. He was a visiting scholar at U. Dortmund, U.Wisconsin-Madison, U. Innsbruck, and U.California-Berkeley in 2004, 2006, 2008, and 2010, respectively. In 2011 he received a Dutch NWO/STW Veni grant (the Dutch equivalent of the US NSF CAREER.) His research interests are in the area of distributed computing; keywords: cloud computing, grid computing, peer-to-peer systems, scientific computing, massively multiplayer online games, scheduling, scalability, reliability, performance evaluation, and workload characterization. Dr. Iosup is the author of over 50 scientific publications and has received several awards and distinctions, including best paper awards at IEEE CCGrid 2010, Euro-Par 2009, and IEEE P2P 2006. He is the co-founder of the Grid Workloads, the Peer-to-Peer Trace, and the Failure Trace Archives, which provide open access to workload and resource operation traces from large-scale distributed computing environments. He is currently working on massivizing OpenTTD.

The proposed formalism takes a structuralist approach allowing decomposition of a cloud usage scenario into elements corresponding to the common cloud service delivery models. Furthermore, the formalism considers several cloud usage patterns that have recently emerged, such as hybrid services and value chains in which mediators are involved, also referred to as value chains with mediators. The scenarios for which the formalism is demonstrated include resource provisioning of global providers of infrastructure and/or platform resources, online social networking services, user-data processing services, online customer and ticketing services, online asset management and banking applications, CRM (Customer Relationship Management) applications, and online social gaming applications. Future versions of the technical report will include extended formalism supporting formal specification of dynamic aspects in cloud resource provisioning, for example, resource provisioning in an elastic manner.
