IBM Systems Magazine, Mainframe - January/February 2017 - 24

For example, a programmer
working on a financing application may need to add support for
a new tax code. She knows where
the changes have to be made but
is unsure of all of the interactions
that may occur. IBM Application
Discovery can quickly locate
the area of the code or data
that needs to change. And it
can perform impact analysis
against not only this particular
transaction but also any other
transaction that might drive the
code or touch the data files being
changed. This approach is more
scientific than searching source
files manually and saves significant time while reducing risk.
"Many clients are moving from
a traditional waterfall development model to an agile, component-based development model,"
explains Mike Fulton, IBM
Distinguished Engineer, CTO for
Enterprise DevOps. "A challenging part of this transformation is

today

determining how to tease apart
the application into components-a fundamental step in
moving to rapid, high-quality
enterprise application development. IBM Application Discovery
makes this transformation easier
and fits naturally into IBM's larger
portfolio of DevOps tools for all
stages of development, such as
IBM Application Delivery Foundation for z Systems and IBM
Application Delivery Intelligence
for z Systems."

Enhanced Visuals
for Updates
IBM Application Discovery finds
all of the artifacts that make up
an application and scans them
into a repository to discover
relationships between the source
code, data and other components. Unlike other technologies,
it works with large applications,
running thousands of transactions and batch applications

Unique Business Value
Becoming a digital enterprise requires organizations to transform. They must
respond quickly to keep up with nimble competitors. This requirement for rapid
and agile delivery of innovative solutions places a greater demand on application
delivery teams.
IBM Application Discovery helps enterprise development teams understand
application interdependencies, complexity and quality across platforms,
environments and languages. The solution, which is part of the full DevOps
for z Systems* capabilities, enables clients to:

Discover and understand business-critical applications and the value they can
bring to a hybrid cloud. Analyzing source code allows developers to understand program and data flows, identify dead code, and understand which
code assets should be exposed in the context of a hybrid cloud.
Evolve existing applications faster and securely to drive digital transformation
Unleash new services, capabilities and value. IBM Application Discovery
and Delivery Intelligence, along with IBM's API and DevOps solutions, allows
companies to integrate and extend enterprise assets to their hybrid cloud
through APIs and evolve them at the speed of business.

across a variety of middleware,
including CICS*, IMS* and DB2*. 
"The developer or architect can
ask a variety of questions of IBM
Application Discovery," Fulton
explains. "It can discover the
impact to the entire application
when making a particular change,
such as the type of field in a database or even creating a new mobile
interface for an application that
may currently only have a traditional green-screen interface."
The solution enables developers, testers, project managers and
architects to analyze all of the
components that make up their
application, including source
code, JCL, workload scheduling information and data files.
Users can easily understand and
change mainframe code based on
data displayed on a dashboard
and other visualizations. IBM
Application Discovery provides
a dashboard that shows which
applications have changed. This
eases the process of modernizing
applications, exposing APIs and
opening development resources.
"IBM Application Discovery
doesn't just dump text onto the
screen. It displays interactive
graphs and provides several styles
of graphs showing relationships
among objects such as variables,
files, transactions and so on," Fulton notes. "Whether you're looking
at the entire application or a COBOL
paragraph, our higher level views
of the application let you quickly
drill down from enterprise application to batch job to source code." 

Hybrid
Cloud Integration
IBM is integrating its expertise in hybrid cloud, APIs and
DevOps with IBM Application
Discovery's mainframe application modernization technology.
