Utility-Oriented Cloud and Grid Computing: A Vision, Hype, and Reality

Grid Computing and Distributed Systems (GRIDS) Laboratory, The University of Melbourne, Australia
Grid computing along with cloud computing, one of the latest buzzwords in the ICT industry, is enabling the creation of Cyberinfrastructure for e-Science and e-Business applications. Despite a number of advances in Grid computing, utility-oriented resource management and application scheduling in such environments continues to be a challenging and complex undertaking. This is because Grids made up of "autonomous" and geographic distributed (a) resources owned by different organizations with different usage policies, cost models and varying load and availability patterns with time; and (b) users' with varying demands and QoS expectations. To address some these challenges, the Gridbus Project at the University of Melbourne has developed grid middleware technologies that support rapid creation and deployment of eScience and eBusiness applications on market-oriented enterprise and global Grids.
In this seminar, we present technological evolution and key challenges in building and managing Utility-Oriented Clouds and Grids. We place emphasis on fundamental challenges of Grid economy, how to design and develop Grid technologies and applications capable of dynamically leasing services of distributed resources at runtime depending on their availability, capability, performance, cost, and users' quality of service requirements. We then introduce Gridbus Project R&D efforts with focus on distributed computational economy for effective management of resources. We briefly present various components of the Gridbus Toolkit and then discuss Aneka (a software system for building enterprise Clouds) and Gridbus Service Broker along with its economic-based scheduling algorithms. Case studies on the use of Gridbus middleware in the creation of various e-Science applications (such as distributed molecular docking and high energy physics) and their deployment on national/international Grids and its impact on emerging Cloud computing paradigm will also be highlighted.
Dr. Rajkumar Buyya is an Associate Professor of Computer Science and Software Engineering; and Director of the Grid Computing and Distributed Systems (GRIDS) Laboratory at the University of Melbourne, Australia. He is the founding CEO of Manjrasoft Pty Ltd., a spin-off company of the University, commercialising innovations originating from the GRIDS Lab. He has authored over 220 publications and three books. The books on emerging topics that Dr. Buyya edited include, High Performance Cluster Computing (Prentice Hall, USA, 1999) and Market-Oriented Grid and Utility Computing (Wiley, 2008). Dr. Buyya has contributed to the creation of high-performance computing and communication system software for Indian PARAM supercomputers. He has pioneered Economic Paradigm for Service-Oriented Grid computing and developed key Grid technologies such as Gridbus that power the emerging e-Science and e-Business applications. He received "Research Excellence Award" from the University of Melbourne for productive and quality research in computer science and software engineering in 2005. The Journal of Information and Software Technology in Jan 2007 issue, based on an analysis of ISI citations, ranked Dr. Buyya's work (published in Software: Practice and Experience Journal in 2002) as one among the "Top 20 cited Software Engineering Articles in 1986-2005". He received the Chris Wallace Award for Outstanding Research Contribution 2008 from the Computing Research and Education Association of Australasia, CORE, which is an association of university departments of computer science in Australia and New Zealand.
Dr. Buyya served as the first elected Chair of the IEEE Technical Committee on Scalable Computing (TCSC) during 2005-2007 and played a prominent role in the creation and execution of several innovative community programs that propelled TCSC into one of the most successful TCs within the IEEE Computer Society. In recognition of these dedicated services to computing community over a decade, President of the IEEE Computer Society, USA presented Dr. Buyya a "Distinguished Service Award" in 2008.
