Transcript of Legacy Modernization 20130623 long
Imagine a boring world where everything
Where graphics don't exist.
Wouldn't it be great
if we could change all that?
But what will it cost?
well That's where
come into the picture
And how much effort
Modernization is an
How should you leverage new technology to benefit existing systems and source?
A Mainframe system should be replaced
Remember that claim?
But would you apply such a theory to other fields?
How about rebuilding a city from
So is it
rewrite computer systems?
But there are
pressures for change
changing regulatory demands
Time to Market
What drives modernization?
Not just one solution!
Is system meeting current needs?
what does it cost to run the system?
can system be replaced by off the shelf software?
Is system barely used & maintained or is it still very alive and growing?
Is the system unique to company's needs?
Add exciting new functionality.
Enhance business logic on the PC/mobile side without having to touch the mainframe applications
I mean the
Maybe you know
just such a world
to the old world
What you need
to ask yourselves
We offer several alternatives
Which option is right for you?
(with/without UI change)
3 Tier Infrastructure
Cities are modernized -
not rebuilt from scratch
ADABAS FOR UNIX/Windows
Natural for UNIX/Windows
Continue to maintain mainframe system
Open Systems GUI interface
that is transparent to the mainframe
short implementation duration
Continue to support mainframe
and pay for mainframe licenses
large existing mainframe team
little open systems experience
don’t want to risk or pay the high price of moving business logic to open systems
move to GUI in minimum time
looking for temporary GUI solution to use until the system is converted
Mainframe components are re-hosted to
compatible components on
(ADABAS to ADABAS,
Natural to Natural,
COBOL to MicroFocus COBOL)
Necessity to continue paying for SAG licenses
Future development is done on mainframe type code which limits open systems development and implementation of widgets etc.
a)Has little remaining mainframe professionals on staff and wants to avoid recruiting future staff necessary to continue and maintain the mainframe.
b)Has moved to open system architecture, has a number of mainframe systems that are not part of core business and their re-hosting will allow him to retire the mainframe and reduce costs
Existing code is moved to open systems with minimum changes.
No necessity to retrain / replace staff because of change of computer languages.
Business logic remains unchanged allowing heavy reduction of testing.
Code Functionality Extrapolation
Mainframe components are automatically converted to components on open systems (Oracle/ openDB2/SQL, MicroFocus COBOL, Java, C#)
Existing code, databases and data are converted automatically to computer languages and databases on open systems with minimum changes.
Client can retire mainframe and reduce costs
Business logic remains unchanged.
Full mainframe functionality is migrated automatically to open system.
Resulting code is similar in structure to mainframe and lacks advantages of full object oriented programming.
Need to retire the MF and remove dependency on SAG products.Customer
Already moved core systems to open system or plans to develop future projects on open systems
Looking for a solution that is relatively quick (1.5-2 year project) and less costly than a system rewrite
Bringing mainframe screens into the
I need to enhance the
what would you
like to add?
But these are
There are big
And I need smartphone
and tablet access
