A Rapidly Changing Business
Environment
The Demands on IT are rapidly Evolving Due to Significant changes in
Business Models, Business Requirements, and Business Processes
• Economics: globalization demands flexibility
• Business processes: changing quickly and
sometimes outsourced
• Growth: at the top of the CEO agenda
• Reusable assets: Leverage what you have
• Information: greater availability for Decision
Making
• Cost Control: Do more with less

Changes Business Expectations of IT
Business dictates that IT executives manage IT as both a commodity
service and for competitive advantage – two very different requirements!
IT’s “Janus Effect”: Deliver Basic IT Services AND Competitive Advantage
“Lower my costs!”
Commodity Service
Basic IT Services
Keeping the “Lights On”
Offshore / Outsourcing
“Deliver new services!”
Competitive Advantage
Business Agility
IT Innovation
Emerging Technology
The business requires technology leaders to anticipate and respond to these market
challenges with relevant initiatives in both areas
New Solutions must support both of these Business Objectives Simultaneously

Some Definitions
Legacy Systems:
“Software systems become legacy when they
begin to resist modification and evolution”
Seacord, Plakosh & Lewis “Modernizing Legacy Systems” Addison Wesley 2003
Core Business Systems:
“Ones that support revenue generating transactions
or are otherwise strategic in nature”
Unisys 2007

Forrester Paper
SOA and Mainframe Users
• Interviewed 20 mainframe users
around the world
• Identifies SOA best practices
• Strongly communicates that you
do not have to replace your
mainframe applications to
achieve the benefits of SOA
• Supports 3D Blueprints initiative
• External release May 15th

What are businesses doing?
• Forrester research commissioned by Unisys:
– ‘Using incremental development and delivery strategies and avoiding big
bang investments, organizations can leverage their mainframe legacy assets
and achieve strong business value as they evolve from yesterday’s
architectures to tomorrow’s SOA-based foundation’.
• Key criteria used to determine approach:
– How well do existing applications fit future business needs?
– Is there on-going support for the platform?
– How does the application fit within the overall portfolio?
– What are the costs, risks, and elapsed time to replace?
• In most cases businesses opted to adapt/evolve
applications through SOA technologies rather than replace

Service Oriented Architecture
• SOA is about business value and productivity, not
technology
• SOA is about enabling business change
– Speeds business change
– Facilitates business connections
– Enhances business control
• SOA is about business design
– Identifies a strategic set of business services
– Creates a digital model of business capabilities that is a
foundation for business flexibility

SOA is Based on “Business Services”
A business service is a
common unit of work
– Maps to business
processes
– Defined in business
terms
– Coarse grained
“Open Account”
“Transfer Funds”
“Execute
Trade”
“Get Portfolio
Balance”
“Authenticate

SOA Architecture for Highest Priority
Application(s) – Create client specific 3D
Blueprints for ClearPath SOA using reference
architectures
3D-Blueprinting ClearPath Application
Workshop
Project Plan and Proof of Concept – Discovery
and identification of application transformation style
to be used (wrap, refactor, etc.); detailed plan;
design and validation of plan
ClearPath skills and tools (knowledge
mining tools optimized for ClearPath;
Agile Business Suite, ePortal)

Implement to Desired End State – Deploy Service
Oriented Infrastructure with application solution
deployed – maximizing investment (through re-use
and portability) and agility

Repeat – Application transformation is an iterative
and incremental process; composite application
evolution necessary to deliver newly minted
services from existing a new applications

Results
Mine knowledge and abstract
it to the right level
As-Is model at the appropriate level of
abstraction. Discovery is the core
service for transformation projects
1. Refactor
Improve application without
changing language or platform
Streamlined application with no dead
code, no database redundancy, etc.
2. Translate
Highly automated language-to- Application in the target language
language translation
replicates functionality for composite
applications
3. Wrap
Encapsulate cohesive
functionality in a SOA harness
Portions of original application turned
into components providing services
4. Replace
Replace applications with new
custom or packaged solutions
Selected new solutions that provide
services that integrate with core
business applications
5. Orchestrate
Orchestrate wrapped and
newly replaced services
The composite solution using existing
and new services (Generally outside of
ClearPath)
