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.

About the Speaker

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. For further information on Dr. Buyya, please visit: http://www.buyya.com
