integrating core systems with contemporary

With so much change needed so quickly, there
is no time nor need to throw away what’s
already providing value. Using technology that
works–COBOL applications–as the innovation
baseline guarantees the future relevance of this
time-proof language for years to come. And
that’s a view shared by those who continue to
use it.

The Only Constant


The ripples of technology change offer near-
limitless opportunity for IT innovators able to
ride the wave of powerful tooling, platforms
and technology. Such as? The drive toward
an API economy, using microservices,
deploying into containers, running on
serverless environments, collaborating in open
frameworks using DevOps to deploy new
facilities that offer enhanced user experiences
and solve real business challenges, using
ostensibly new technology.

Let’s consider some scenarios faced in IT
teams. It’s a wish list of “we want to”:

Unlock the business functionality

embedded with a COBOL system to
reuse it as a component, service, object,
microservice or whatever

Change our underlying data model but not

the core applications

Provide a more user-friendly customer

experience to an existing application

Integrate new third-party applications with

our core business systems

Deploy some business applications in


These disparate requirements represent
innovation in the context of current core
business systems, building in new capability
from a position of established strength, of
power, rather than razed earth. In each case,
the COBOL application is being redeployed
or reused, according to the technical use
case. The tooling is there, it merely requires
the awareness and the right approach. You
might call it a modernization strategy (I
