Combining Web
Services and the Grid -
Enabling a New Way to Think About IT
Abstract
Specifications that
standardize major aspects of Grid computing are currently proposed that rely
on Web Service technology. The Web Service community in turn is adding
basic specifications to its stack to make both sets of standards work hand
in hand. We sketch how the combination of these efforts enable
virtualization of both, hardware and software resources. The resulting
infrastructure provides the underlying plumbing for autonomic feedback
loops. Specific kinds of such feedback loops may be seen as base for
dynamic provisioning of applications and their infrastructures. The role of
choreographies in provisioning is outlined. Finally, application structures
suitable for being provisioned "on demand" are envisioned.

Frank
Leymann's bio
Frank
Leymann is a full professor of computer science and director of the Institute
of Architecture of
Application Systems at the University of Stuttgart, Germany. His research
interests include service oriented computing, workflow- and business process
management, transaction processing, and architecture patterns.
Before
accepting his professor position he worked for two decades for IBM Software
Group buildi ng database and
middleware products: He built tools supporting conceptual and physical database
design for DB2; built performance prediction and monitoring tools for an object
database system; was co-architect of a repository system; built both, a
universal relation system as well as a complex object database system on top of
DB2; and co-architected the MQSeries family. In parallel to that, Frank worked
continuously since the late 1980s on workflow technology and has become the
father of IBM’s workflow product set.
He was
appointed IBM Distinguished Engineer in 2000 and elected member of the IBM
Academy of Technology in 1994. As member of the IBM Software Group Architecture
Board he contributed to the architecture and strategy of IBM’s entire
middleware stack as well as IBM’s On Demand Computing strategy. From 2000 on,
Frank worked as co-architect of the Web Service stack. He is co-author of many
Web Service specifications, including WSFL, WS-Addressing, WS-Metadata
Exchange, WS-Business Agreement, and the WS-Resource Framework set of
specifications; together with Satish Thatte, he was the driving force behind
BPEL4WS. Frank published many papers in journals and proceedings, co-authored
three text books, and holds a multitude of patents especially in the area of
workflow management and transaction processing.

Self-Managed Cells
and their Federation
Abstract
Future e-Health
applications will involve mobile users, possibly with on-body sensors
interacting with a ubiquitous computing environment that detects their
activity, current context and adapts accordingly. Continuing advances in
the miniaturization and bio-compatibility of physiological sensors enables
the realisation of future ubiquitous computing environments that can
dramatically enhance the healthcare provided in the community to
individuals with chronic conditions and to improve their quality of life.
However, while devices for insulin delivery, multi-programmable brain
stimulators and implantable cardioverter-defibrillators (ICD) have been
developed and are soon to be endowed with wireless communication
capabilities, the software infrastructure which allows their secure
interconnection, configuration and adaptation to current context remains a
significant challenge. The promise of such biquitous computing environments
will not be realised unless these systems can effectively “disappear”; and
for this they need to become autonomous by managing their own evolution and
configuration changes without explicit user or administrator action.
For self-management in
ubiquitous systems to become a reality, it is necessary to define and
implement architectures which can scale down to small lightweight
structures with local decision making capabilities. The management
functionality must be automatically integrated and adapted to the specific
application requirements without human intervention. Autonomous, self-managed
cells (SMC’s) must be composable to form larger cells but also need to
collaborate and integrate with each other in peer-to-peer relationships as
well as across multiple levels of abstraction relating to hierarchical
service relationships.
This talk will describe
the basic architecture of an SMC, and various forms of federation
between/among SMC’s. The relevance of this structure to expected scenarios
will be demonstrated.

Joe
Sventek’s bio
Joe Sventek is
the Professor of Communication Systems in the Department of Computing Science
at the University of Glasgow, Scotland. His research interests include
rogrammable networks, embedded systems, closed-loop network management, and
distributed system architectures.
Prior to
joining Glasgow,
he had a distinguished research career (as a distinguished engineer and
research fellow) at Lawrence Berkeley Laboratory (1979-1986), Hewlett-Packard
(1987-1999), and Agilent Technologies (1999-2002). Professor Sventek was the principal
author of the original OMG CORBA specification as well as several of the Common
Object Services (Trading, Events, Naming); he also was the rapporteur for the
TeleManagement Forum’s Technology Neutral Architecture document released in
early 2003. He has been the general chair for TINA99 and Middleware 2001,
programme chair for COOTS98, TINA99, and Middleware 2000, and a member of
programme committees too numerous to mention. He is an advisor to the
TeleManagement Forum Board, is an adviser to the Wiley Series in Communications
Networking and Distributed Systems, and a member of the UK Computing Research
Committee.
