题目: Cloud Computing: Challenges and Opportunities 报告人: Cheng-Zhong Xu，Wayne State University, Detroit, USA 时间: Dec. 28th, 2009, 14:30, 地点：Meng Minwei Building 109 摘要：Cloud computing, unlocked by virtualization, is emerging as an
increasingly important service-oriented computing paradigm. Management is key
to providing accurate service availability and performance data and to
enabling on-demand real-time capacity planning to meet service demands
dynamically. This is because virtualization does not reduce the complexity of
a system. In fact, having multiple virtual machines (VMs) running on top of a
shared physical computing infrastructure increases the overall system
complexity and poses new challenges in systems management. Optimizing one
component may compromise the others, leading to overall performance
degradation. Frequent component failures here and there would even cause low
system productivity. This talk will start with an introduction to cloud computing and a review of
challenge issues in the management of large scale cloud systems. Emergent
feedback control and machine learning approaches will be presented for
tackling the challenges of scale and complexity in current and future cloud
systems. Biographical Sketch of the Speaker: Dr. Cheng-Zhong Xu is a Professor in the Department of Electrical and Computer
Engineering of Wayne State University, the Director of the Laboratory for
Cloud and Internet Computing, and the Director of Sun's Center of Excellence
in Open Source Computing and Applications (SUN OSCA). He received B.S. and M.
S. degrees in Computer Science from Nanjing University and a Ph.D. from the
University of Hong Kong in 1993. Dr. Xu's research interest includes resource
management in distributed and parallel systems, cloud and Internet computing,
and high performance cluster computing. He has published extensively in these
areas. He was a main inventor and promoter of diffusive load balancing
algorithms in parallel computing, and a key innovator of model-predictive
feedback control and reinforcement learning-based systems management
approaches for the provisioning of high service availability of Internet
servers and datacenters. Dr. Xu was the leading author of the book "Load
Balancing in Parallel Computers" (Kluwer Academic/Springer Verlag, 1995). It
was arguably the first that addressed the load balancing issue systematically.
His recent book "Scalable and Secure Internet Services and Architecture" (
Chapman & Hall/CRC Press, 2005) provided an in-depth analysis of the Internet
services in a unified framework from the performance perspective. Dr. Xu is an editor of a number of leading journals in his areas, including IE
EE Transactions on Parallel and Distributed Systems and Journal of Parallel
and Distributed Computing. He is a recipient of "Faculty Research Award" of
Wayne State University in 2000, President's Award for Excellence in Teaching
in 2002, and Career Development Chair Award in 2003.
