The document discusses legacy monolithic applications and the challenges of migrating them to the cloud. It notes that 80% of actively used code is in COBOL and that enterprise applications are large, complex, and long-lived. Many organizations expect cloud migrations to take over a year to complete. The document recommends analyzing the application portfolio and individual applications using CAST software to understand architecture and define a migration roadmap. CAST software can reverse engineer applications, provide insights into architecture and data flow, and identify remediation opportunities to enable the transformation journey.

The cloud isn’t only about cloud native applications.
It is also about dealing with Monolithic Legacy Applications.
80%of the world’s actively used code
is in COBOL (>220B lines)
200xas many COBOL transactions take
place each day than Google searches
The “starburst effect”:
the advance of cloud & mobile computing
leads to“a surge of back-end transactions”.

Enterprise Business
Applications are
large & complex.
Frequently, they form the
core on which newer
capabilities are added.
This is a real z/OS application flowchart.
It’s no more than above-average in complexity.

large & complex.
They are long-lived,

seems like a long & tough journey.

Out of the Box Power Point Output based on
the custom segment
 CAST Highlight helps create a baseline
of the portfolio in a matter of days.
 Leverage the cross-analysis abilities to
define segments of apps to: re-host, re-
platform, rewrite or replace.
 Drill-down analysis of applications.
 Export reports.
 Generate signature-ready outputs
that embed fact-based analysis at
both Portfolio & Application levels.
Where to start: Analyse portfolio & develop roadmap
