7. Before SOA ?
Significant business intelligence exists in core systems
"200 Billion lines of COBOL code in existence" eWeek
"5 Billion lines of COBOL code added yearly“ Bill Ulrich, TSG Inc.
“2 Million COBOL developers" Gartner
"Majority of customer data still on mainframes“ Computerworld
“Replacement costs $20 Trillion” eWeek
• Rewriting - is it an option.....
– How long will it take? (lose strategic
benefit)
– Who will do it? (who has the business
knowledge?)
– How much will it cost?
– Risk?

8. Key questions ? Is there value in
physically co-
locating new SOA
• Stores 70% * of corporate data
applications and
middleware with the
• Contains estimated $3 Trillion** System z resources?
in core assets
Should we consolidate
• Estimated applications onto a centralized
replacement costs of $20T *** platform like System z,
or push a lot of our new
• CICS handles transactions infrastructure out to
valued at over $1 distributed servers and
trillion/week*** have a multi-tiered
approach?
• IMS handles over 50 Billion
Trans/day
Does deployment really
matter?

11. SOA & Application Development
Some key points :
• Reuse : it’s important to have capability to reuse business
applications in CICS or IMS
• Agility : speed and velocity is the critical path to provide new
services
• Standard : it’s important to use standard to integrate legacy
applications with distributed platforms
