Messaging Backbone
 Point-to-Point connection
between applications
 Simple, basic connectivity
 EAI connects applications
via a centralized hub
 Easier to manage larger
number of connections
 Integration and choreography of
services through an Enterprise
Service Bus
 Flexible connections with well
defined, standards-based
interfaces

What are the barriers to business flexibility and reuse?
 Lack of business process
standards
 Architectural policy limited
 Point application buys to
support redundant LOB
needs
 Infrastructure built with no
roadmap

What is the top focus of businesses?
 75% of CEOs place a high or very
high priority on the ability to
respond rapidly
 Only 1 in 10 CEOs believe that their
organization has the ability to be
very responsive to react to changing
market conditions
Source: IBM Global CEO Survey, Feb 2004
“'We are being told that flexibility in business will be more important than operational
efficiency. Overall, 62 per cent of respondents believe that we might be arriving at another
age where we see the demise of some forms of business because they could not adapt
fast enough.”
–Bryan Glick, Computing 21 Sep 2004

What’s on the minds of 450 of the world’s leading CEOs?
CEO needs
CIO challenges
 Revenue growth with cost
containment
 Aligning IT and business goals to
grow revenue and contain costs
 Building responsiveness and agility
into the organization through IT
 How can IT help enable people and
teams to be more effective
 Key competency: responsiveness
 Critical success factor:
enable effectiveness of people and
processes

Consistent imperatives ….
Flexibility
… Grow faster
 Bekins increased revenue by $75M through
integration with business partners to serve a new
market
 PineBank increased customer traffic by 300% and
revenues by $8M
Efficiency
… Spend less
 Kookmin Bank should save $250 million from
reduction of duplicate processes
 Volkswagen realized a 20% productivity gain
Responsiveness
… Increase customer satisfaction
 Dassault Aviation reduced concept-to-runway
development time by 30%
 British Petroleum decreased user-provisioning
time from 5 days to 10 minutes

Why SOA now?
 To keep pace with global competition:
 “We are taking apart each task and sending it
… to whomever can do it best, … and then
we are reassembling all the pieces”
from Thomas Friedman’s ‘The World is Flat’
 The standards and technology are finally in
place, with broad industry support
 Availability of best practices for
effective governance
 The necessary software to get started
is available today

What differentiates SOA from claims like this in the past?
Standards
 Broadly adopted Web
services ensure welldefined interfaces.
 Before, proprietary
standards limited
interoperability
Organizational
Commitment
 Business and IT are united
behind SOA (63% of
projects today are driven by
LOB)*
 Before, communication
channels & ‘vocabulary’ not
in place
Degree
of Focus
Connections
Level of Reuse
 SOA services focus on
business-level activities &
interactions
 Before, focus was on
narrow, technical sub-tasks
 SOA services are linked
dynamically and flexibly
 Before, service interactions
were hard-coded and
dependent on the
application
 SOA services can be
extensively re-used to
leverage existing IT assets
 Before, any reuse was
within silo’ed applications

Becoming an On Demand Business
An On Demand Business is an enterprise whose business processes —
integrated end-to-end across the company and with key partners,
suppliers and customers — can respond with speed to any customer
demand, market opportunity or external threat.

Four Characteristics of On Demand
 Integration
Providing the linkage between people, processes, and data
 Open
Supporting a strong commitment to standards for OS, Language and Web
Services/SOA
 Virtualized
Providing a flexible Build-time and Runtime environment for developing and
running applications across a highly distributed IT architecture
 Autonomic
Self regulating … self healing … self maintaining

SOA: Service Oriented Architecture
• An approach for building distributed systems that
allows tight correlation between the business
model and the IT implementation.
• Characteristics:
 Represents business function as a service
 Shifts focus to application assembly rather than
implementation details
 Allows individual software assets to become
building blocks that can be reused in developing
composite applications representing business
processes
 Leverages open standards to represent software
assets

SOA Concepts
 What is a service?
 A coarse grained, self-contained entity that performs a distinct business function
 What is a service description?
 A standards based interface definition that is independent of the underlying
implementation
 What is service discovery?
 Use of a service registry to access service interface descriptions at buildtime or runtime
 How do services interact?
 Through loosely-coupled, intermediated connections
 What is service choreography?
 Control of the execution sequence of services in ways that implement business processes
 How are SOA solutions created and enhanced?
 Using tools and middleware according to SOA principles

Three Key Concepts for the Foundation for On Demand
 Build –Model Driven Architecture
A style of enterprise application development and integration based on
using automated tools to build system independent models and
transform them into efficient implementations1
 Run –Service Oriented Architecture
An approach for designing and implementing distributed systems that
allows a tight correlation between the business model and the IT
implementation
 Manage –Business Performance Management
An approach to systems management that tightly links IT concerns with
business process concerns

MDA: Model Driven Architecture
Key Concept:
 An integration of best practices in Modeling,
Middleware, Metadata and Software Architecture
 Based on standard Models, Metadata Models,
and Model Transformations
Model Driven:
 (UML, MOF, CWM…)
 Platform Independent Business Models (PIM)
 Platform Specific Models (PSM)
 Mappings : PIM <==> PSM, PSM<==> PSM
(Relative term!)
Metadata Driven:
 (MOF, XSD, XMI)

Key Benefits:
 Improved Productivity for Architects, Designers,
Developers and Administrators
 Lower cost of Application Development and
Management
 Enhanced Portability and Interoperability

SOA requires effective IT Governance
“Effective IT Governance is the single most important predictor of
value an organization generates from IT.”
MIT Sloan School of Mgmt.
 Increasing Share Price Professional investors are willing to
pay premiums of 18-26% for stock in firms with high governance
 Increasing Profits “Top performing enterprises succeed where
others fail by implementing effective IT governance to support their
strategies. For example, firms with above-average IT governance
following a specific strategy (for example, customer intimacy) had
more than 20 percent higher profits than firms with poor
governance following the same strategy.”
 Increasing Market Value “On average, when moving from
poorest to best on corporate governance, firms could expect an
increase of 10 to 12 percent in market value.”

What do you really mean by SOA Governance …
People
Governance comes from the root
word “Govern”. Governance is the
Services
structure of relationships and
processes to direct and to control
the SOA components in order to
achieve the enterprise’s goals by
adding value while balancing risk
versus return
49

Processes
The focus of SOA is the
Services Model
The governance model defines:
 What has to be done?
 How is it done?
 Who has the authority to do it?
 How is it measured?
