Why COBOL is strategic in the 21st Century

Page 2: The Value of Legacy

The Value of Legacy

• Legacy applications are a valuable resource

– An investment of over $5 trillion– …at the heart of every large enterprise– …running the world’s economy

• …which can be reused and extended

– As core services– …in new products– …delivered to new channels

• …providing enduring business value

– Reducing costs &– …driving agility– …with least risk

75% of the world's business

data is in COBOL

There are between 180 billion

and 200 billion lines of

COBOL code in use worldwide

15% of all new applications (5

billion lines) through 2005 will

be in COBOL. (Gartner)

Emergence of Service-Oriented Architectures

Focus on ‘re-use’ at the business level

…based on XML & Web services

Web services is independent and inclusive of:

– Any platform

– Any language

– Any architecture

J2EE and .NET

“The secret to success lies in building bridges between the old and the new”

The Choices for Moving

Page 6: The Value of Legacy

The Lift & Shift Opportunity

Reduced Costs– 80% Savings in hardware and software achievable– Rapid ROI utilizing existing staff skills, data and applications

Increased Agility– Modern service-based architecture using XML, Web

Services– Leverage the .NET or J2EE Application Environments

Lower Risk– Combination of Micro Focus running on an Enterprise-

strength platform and System Integrator expertise provides low-risk route to lower TCO

Lombard Insurance - Overview

Lombard Canada Ltd. is one of the oldest property and casualty insurance operations in Canada

Commercial, personal, and specialized insurance Consolidated gross premiums written totaling C$

1.94 billion Total shareholders' equity of C$ 861.7 million Top 5 Insurance Company in Canada Wholly owned subsidiaries of Northbridge

Financial Corporation (NB on the TSE)

Lombard – Why Migration? Diminishing availability of the highly specialized

skill set required to maintain a mainframe environment

Shortage of innovation in the mainframe ISV ecosystem

Need for increased flexibility Desire to stay ahead of the curve and continuing

the tradition of technology leadership in the insurance industry

Create, Reuse and Extend

Reuse existing COBOL Business logic in .NET

Use Procedural or Object Oriented COBOL under .NET

Extend COBOL applications to utilize .NET functionality– Access to .NET Framework Classes

Why use XML?

XML brings data to the web XML is now commonly deployed as an

integration piece between applications or application components (EAI, B2C and B2B)

XML is a simple but extensible and mature technology

By accessing XML from COBOL it becomes easier to Integrate COBOL business logic and data to systems across the enterprise

A key technology to enable e-business

Page 36: The Value of Legacy

Micro Focus COBOL/XML Syntax

Provide a higher level COBOL orientated approach to COBOL/XML

Adds significant new syntax to handle XML documents to consume, create, update and XML documents from COBOL– Based on familiar approach used with COBOL I/O

support– Provides both SAX style or DOM style parsing

Map to/from XML W3C Compliant Schemas

Business Challenges:• Differing requirements for on-line single share order entry and high

volume bulk share processing• Security. Integrity, and Consistency of Share Processing an absolute

requirement Technical Challenges:

• Integrate 3rd Party System running on UNIX with existing Windows based COBOL System ‘Mozart’.

• Deliver Robust, Reliable High Performance System Solution:

• Micro Focus Net Express XML Early Adopter Software enabled data integration between the two separate systems

• A small XML I/O processor was built that delivered bulk orders to ‘Mozart’ via XML and returned the status back

Result:• Successful integration of new Share System for bulk orders without

impacting existing system

Why COBOL is strategic in the 21st Century Reuse COBOL assets

– 200 billion lines of COBOL in use today– 75% of business data processed in COBOL– 15% of all new programs will be written in COBOL

Reuse COBOL Skills Powerful Development environments improve

programmer productivity COBOL remains a strong business class language

delivering performance and maintainability “Its not your Fathers COBOL!”

– COBOL is now a “First Class Citizen” in .NET– COBOL is Object Orientated– COBOL works with other technologies in the enterprise (not

just .NET, also J2EE, XML and Web services)

Legacy Platforms and Legacy Environments should be differentiated from mission critical business logic

Page 41: The Value of Legacy

How can I help? Teach more COBOL

– Part of the future Howling envisions includes bringing in new talent, which likely won't have a strong mainframe skill set. "We've outlived and outgrown the mainframe," Howling said. "With [recent] graduates, you start talking mainframe and they're not interested … that's where my talent pool is coming from, and they won't be learning COBOL in universities."

Show COBOL is has moved beyond the mainframe Show COBOL is modern, agile and strategic Show how COBOL has a future Show how COBOL works within the enterprise

today Show why COBOL is a valuable and strategic skill
