A Rapidly Changing Business Environment
The Demands on IT are rapidly Evolving Due to Significant changes in Business Models, Business Requirements, and Business Processes
*Sources: CBDi
• 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
The business requires technology leaders to anticipate and respond to these market challenges with relevant initiatives in both areas
Commodity ServiceBasic IT ServicesKeeping the “Lights On”Offshore / Outsourcing
Competitive AdvantageBusiness AgilityIT InnovationEmerging Technology
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
New Solutions must support both of these Business Objectives Simultaneously
“Lower my costs!” “Deliver new services!”

Two Sides of Legacy Applications
It’s an asset! – Functional– Customized– Well-tuned– Supports mission critical
operations– Robust– Secure
It’s a liability!– Uses old technology – Requires hard-to-find skills– Lacks documentation – Is hard to maintain– Resists change, integration, and
replacement– Inhibits organizational agility

Forrester Paper
• 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

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

Discover + 5 Transformation Styles “As-is” to ‘To-be” application
Style Definition Results
Discover 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-language translation
Application in the target language 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)
Rationalize
