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

• 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


Page 18

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

1 Defined Strategy for Applications in Portfolio –Identify potential SOA candidates

3D-Blueprinting Experiential Workshop

2 SOA Architecture for Highest Priority Application(s) – Create client specific 3D Blueprints for ClearPath SOA using reference architectures

3D-Blueprinting ClearPath Application Workshop

ClearPath Reference Architectures

3 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)

Abstraction – Rules Modeler, Knowledge Modeler

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

Next-Generation Server Architecture

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

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
