Abstract:
Computing is being transformed to a model consisting of services that
are commoditised and delivered in a manner similar to utilities such as
water, electricity, gas, and telephony. In such a model, users access
services based on their requirements without regard to where the
services are hosted. Several computing paradigms have promised to
deliver this utility computing vision and they include Grid computing,
P2P computing, and more recently Cloud computing. The latter term
denotes the infrastructure as a “Cloud” in which businesses and
users are able to access applications from anywhere in the world on
demand. Cloud computing delivers infrastructure, platform, and software
(application) as services, which are made available as
subscription-based services in a pay-as-you-go model to consumers.
These services in industry are respectively referred to as
Infrastructure as a Service (Iaas), Platform as a Service (PaaS), and
Software as a Service (SaaS). To realize Cloud computing, vendors such
as Amazon, HP, IBM, and Sun are starting to create and deploy Clouds in
various locations around the world. In addition, companies with global
operations require faster response time, and thus save time by
distributing workload requests to multiple Clouds in various locations
at the same time. This creates the need for establishing a computing
atmosphere for dynamically interconnecting and provisioning Clouds from
multiple domains within and across enterprises. There are many
challenges involved in creating such Clouds and Cloud interconnections.
This tutorial (1) presents the 21st century vision of computing and
identifies various IT paradigms promising to deliver the vision of
computing utilities; (2) defines the architecture for creating
market-oriented Clouds and computing atmosphere by leveraging
technologies such as VMs; (3) provides thoughts on market-based resource
management strategies that encompass both customer-driven service
management and computational risk management to sustain SLA-oriented
resource allocation; (4) presents the work carried out as part of our
new Cloud Computing initiative, called Cloudbus: (i) Aneka, a
software system for providing PaaS within private or public Clouds and
supporting market-oriented resource management, (ii) internetworking of
Clouds for dynamic creation of federated computing environments for
scaling of elastic applications, (iii) creation of 3rd party Cloud
brokering services for content delivery network and e-Science
applications and their deployment on capabilities of IaaS providers
such as Amazon and Nirvanix along with Grid mashups, and (iv) CloudSim
supporting modelling and simulation of Clouds for performance studies;
and (5) concludes with the need for convergence of competing IT
paradigms for delivering our 21st century vision along with pathways
for future research.

Biography:
Dr. Rajkumar Buyya is Professor of Computer Science and Software
Engineering; and Director of the Cloud Computing and Distributed Systems
(CLOUDS) Laboratory at the University of Melbourne, Australia. He is
also serving as the founding CEO of Manjrasoft Pty Ltd., a spin-off
company of the University, commercialising its innovations in Grid and
Cloud Computing. He has authored and published over 300 research papers
and four text books. The books on emerging topics that Dr. Buyya edited
include, High Performance Cluster Computing (Prentice Hall, USA, 1999),
Content Delivery Networks (Springer, Germany, 2008) and Market-Oriented
Grid and Utility Computing (Wiley, USA, 2009). He is one of the highly
cited authors in computer science and software engineering worldwide.
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 Distributed
Computing and developed key Grid and Cloud Computing technologies such
as Gridbus and Aneka that power the emerging e-Science and e-Business
applications. Software technologies for Grid and Cloud computing
developed under Dr. Buyya's leadership have gained rapid acceptance and
are in use at several academic institutions and commercial enterprises
in 40 countries around the world.
Dr. Buyya has led the establishment and development of key community
activities, including serving as foundation Chair of the IEEE Technical
Committee on Scalable Computing and four IEEE conferences (CCGrid,
Cluster, Grid, and e-Science). He has presented over 200 invited talks
on his vision on IT Futures and advanced computing technologies at
international conferences and institutions in Asia, Australia, Europe,
North America, and South America. These contributions and international
research leadership of Dr. Buyya are recognised through the award of
"2009 IEEE Medal for Excellence in Scalable Computing" from the IEEE
Computer Society, USA. For further information on Dr. Buyya, please
