6. So what is holding organizations back?
How to handle the
monolithic code?
How to bring agility?
How to expose Z assets
to mobile world?
Is it possible to reuse
existing SOA modules?
Will it handle load
in peak hours?
Digital enablement of mainframe.
Will it be a success?
How to ensure security
and governance?
Typical Patterns:
• Spaghetti application
• SOA-based applications
