UNLEASH
Business Applications
IBM Application Discovery unlocks new value and accelerates
the adoption of hybrid cloud solutions
By Brett Martin k Illustration by Nick Reddyhoff

T

he name of the IT game
is new value creation.
Often, one of the fastest
paths is to unleash trapped value
by cloud-enabling existing core
business apps and data. However,
this can be risky. With billions of
lines of code, often intertwined
and decades old without proper
documentation, these apps are
at the heart of the business. The
thought of tinkering with them
might create fear in the best of us.
But fear no more: As a result
of its EZSource acquisition
and a series of strategic
enhancements, IBM released
IBM Application Discovery,
a powerful tool for clients
looking to create competitive
advantage and accelerate
cloud adoption. Developers
can use it to quickly identify,
change and cloud-enable core
business applications via APIs.
By combining IBM's strength
in digital transformations, API
economy, hybrid clouds and
enterprise DevOps with IBM
Application Discovery's capability
to understand and analyze
applications, businesses can more
rapidly discover new ways to take
advantage of their mainframe.

Many companies want to modernize their software to support
the business moving to a digital
enterprise. However, they're
averse to modifying aging business-critical applications because
of the risk. Code changes often
rely on manual analysis and are
therefore error prone, depending
on only a few employees with
domain expertise. Applications
are often poorly documented,
which can result in increased
risk and effort. Code changes can
be difficult if the understanding
of business-critical applications
is limited.
"Enterprises have a wealth
of valuable information and
insights locked in their timetested code," says Sherri L.
Hanna, portfolio marketing
manager, DevOps for IBM
z Systems*. "Many of their
applications have been running
well for 40 years or more. They're
afraid to touch them because
they're not broken and they don't
have accurate documentation on
code that has been maintained
over the years by developers
who may no longer be with
the company. IBM Application
Discovery gives them the

blueprint they need to modernize and improve the
equity they have in their existing systems."

Update Code Efficiently
Today's applications can be made up of billions of
lines of code-over 220 billion lines of COBOL are in
production (on.wsj.com/1CTX36D)-and updating
them can take weeks, months and sometimes
years. Reading that much code isn't feasible, which
is where a tool like IBM Application Discovery
provides value.
