Market-Oriented Cloud
Computing: Vision, Hype, and Reality of Delivering Computing as the 5th Utility
Rajkumar Buyya The 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 keynote talk (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.
Evolvement from physical grid to virtual grid
Lian Li Abstract Grid is rapidly grown as a common
computing platform within lasted twenty years, which integrals various discrete
resources into a uniform system to be shared by numerical users, not only the utilizers but also
developers, without perception of allochthonous and heterogeneity. Up to date, the grid is evolving from
physics grid to virtual grid, i.e. from a grid programming oriented the
resources to a grid programming oriented services. It results the application
of grid more fields and scopes. The virtual technique has promoted greatly the
emerging of many standards on grid, and catalyzes a new programming for grid
application, which is called orchestration of services, The virtual grid change
the fashion and concept of using computers. In this report, we discuss some theoretical
points of virtual technique, the current situation of grid standards, and the
problems in grid system developing.
Virtualization Technology for Computing System
Hai Jin Abstract Virtualization technology (VT) being
a re-emerging technology has become a hot topic in recent years. It is a
decoupling technique that separates system software from hardware platform
while making applications run pervasively. Many academic institutes and
research labs from industries have devoted great research efforts in various
aspects. In 2007, Chinese Ministry of Science and Technology initialized a
basic research project (973 project) with 6 universities and 2 research
institutes on virtualization technology for computing system in many topics,
such as architecture design philosophy of virtualization technology, VT design
for single computing system, VT design for multiple computing systems, user
environment for VT, security, reliability and trust issue related to VT, and
performance evaluation and benchmarks for computing system with VT. In this
talk, we will give insight for this project in details, including its
motivation, goal, and research issue etc. Some preliminary research results with
this project will also be illustrated.
Jin is a senior member of the IEEE and a member of the ACM. Jin is the member of Grid Forum Steering Group (GFSG). He has co-authored 15 books and published over 400 research papers. His research interests include computer architecture, virtualization technology, cluster computing and grid computing, peer-to-peer computing, network storage, and network security. Jin is the steering committee chair of
International Conference on Grid and Pervasive Computing (GPC), Asia-Pacific
Services Computing Conference (APSCC). Jin is a member of the steering
committee of the IEEE/ACM International Symposium on Cluster Computing and the
Grid (CCGrid), the IFIP International Conference on Network and Parallel
Computing (NPC), and the International Conference on Grid and Cooperative
Computing (GCC), International Conference on Autonomic and Trusted Computing
(ATC), International Conference on Ubiquitous Intelligence and Computing (UIC). |
