Tutorial 1: IT Service Management
in a Service Oriented Environment: Best Practices, Challenges, and Shared
Experiences
Christopher Ward (IBM) and Claudio Bartolini (HP)
IT Service Management using Service Oriented Architectures
(SOA) introduces a new way of looking at business and organizations. For the
business, SOA provides a conduit to expose not just its customer facing
services but also its internal processes. For the organization, SOA provides a
way of increasing its competitive edge through greater flexibility and
responsiveness to external and internal change. Within an IT organization SOA
means efficiently delivering IT services to their lines of business as well as
managing the SOA architectures that their businesses are constructing. This
task is magnified in the emerging global economy, as IT management extends to
global scope and becomes progressively automated in execution. In fact, a new
IT Service Management (ITSM) model is emerging to address these and other
challenges including the need for efficient coordination of people and tools
across global organizations and different silos of management, and alleviating
the growing relative cost of labor to an IT organization. This new model
implies a greater degree of human activity coordination through standardized
processes, a greater degree of process automation via relevant tools, and a
more comprehensive and federated approach to IT configuration management data,
system data and performance measurement data, resulting in qualitative and
quantifiable improvements in IT service delivery.
In this tutorial we will describe the transformation that
is taking place within IT organizations to provide IT service management rather
than just IT systems management. In this new services oriented paradigm, the
traditional focus on technology to provide systems management is augmented with
process management to provide a service management focus. The tutorial starts
with an introduction to IT organizations and what IT service management
entails. The tutorial provides a brief overview of ITIL including the service
support domain of Configuration Management, Change Management, Incident
Management and Problem Management and Release Management, and service delivery
domain encompassing Service Level Management, Financial Management, Capacity
Management, Availability Management and Service Continuity Management. The
tutorial then illustrates how services oriented architecture provides the ideal
enabler for process based IT service management, by following the lifecycle of
a representative IT service request. The tutorial concludes with a discussion
on adoption challenges, including handling process variances, deployment
planning process monitoring and education.

Introduction to IT Service Management (ITSM)
·
How SOA and ITSM extend flexibility within businesses
operations
·
IT Best Practices based and the IT Infrastructure Library
(ITIL)
·
How ITSM in an SOA environment leverages ITIL to provide
reliable, efficient, measurable service management
·
ITSM challenges to adoption and deployment
At the conclusion of the course, participants are expected
to have an introductory understanding of IT Service Management including the
four major elements: Organization, Process, Technology, and Information. The
participants will be conversant in ITIL and understand the basics of the
service support domain and the delivery domain. The participants will also
understand how SOA enabled ITSM can be deployed for IT service management and
the major benefits and challenges.

Tutorial 2: Building Business Driven Grid
Solutions Using Open Source Globus Software
Steve Tuecke (Univa)
Learn how to develop and deploy Grid solutions that have
real business impact, using the open source software. Most Grid deployments to
date have focused on IT-centric issues such as server utilization and increased
throughput for parallelizable applications. But the true value of Grid is in
the business capabilities that it enables, especially in such strategic
processes as new product design and innovation. This presentation examines best
practices for designing, deploying, and operating secure, scalable solutions
that allow distributed groups of knowledge workers to collaborate more
effectively.
Topics include:
·
The challenges of managing resources and data in a large
distributed environments
·
Using Globus components and
services to enable interoperability among computing, data and communications
resources across the enterprise
·
Similarities between commercial requirements and eScience Grid deployments
·
Guidelines for assembling Grid solutions using open source
Globus software
Biography
Steve Tuecke cofounded the Globus Alliance, originally known as the Globus Project, with Dr. Ian Foster and Dr. Carl Kesselman.
He was responsible for managing the architecture, design, and development of Globus software, as well as the Grid and Web Services
standards that underlie it. Tuecke was Univa.s first
CEO, leading the company through its first round of funding and beta product
release. He began his career in 1990 as a software engineer for Foster in the
mathematics and computer science division at Argonne National Laboratory. In 1995,
Tuecke helped create the Distributed Systems Laboratory at Argonne
which, under his management and technology leadership, became the premier Grid
research and development group in the world. In 2001, Tuecke focused on Globus architecture and design, creating Grid and Web
Services standards, and expanding corporate relationships. In 2002, Tuecke
received Technology Review magazine's TR100 award, which recognized him as one
of the world's top 100 young innovators. The same year, he also was named to
Crain's Chicago Business "Forty Under 40"
and described as one of the Chicago
area's "best and brightest." In 2003, he was named (with Foster and
Kesselman), by InfoWorld magazine as one of its Top 10 Technology Innovators of
the year. Tuecke graduated summa cum laude with a B.A in mathematics and
computer science from St. Olaf College.
Tutorial 3: From Business Process
Modeling with BPMN & BPDM to Business Process Execution with BPEL-* &
SCA
Pablo Irassar (IBM) and Matthias Kloppmann (IBM)
The objective of this tutorial is to provide a solid
understanding of the life-cycle of standards-based business processes, with an
emphasis on the associated open standards. That life-cycle starts with business
level modeling where we'll go into the creation of business processes using the
Business Process Modeling Notation (BPMN) and its relationship to the emergent
Business Process Definition Metamodel (BPDM). At that
level structural elements, tasks, compensations, key performance indicators and
other key elements of orchestration and choreography can be associated with
processes, and processes can be analyzed and their behavior be simulated to
anticipate later runtime characteristics.
From there, business processes will be refined and
augmented with IT-specific information to result in a process runnable on a process execution middleware. We'll go into
the executable process constructs provided by existing and upcoming standards
for executable business processes, such as the Business Process Execution
Language (BPEL), BPEL extensions to incorporate people into business processes
(BPEL4People) and others. Finally, such a process cannot be run on its own, but
needs to be linked to the services it invokes, and deployed onto a real system.
Here we take a closer look at the associated framework provided by the Service
Component Architecture (SCA) and introduce its concepts.
