DEVOPS DRIVES
INNOVATION AND
MODERNIZATION ON Z
Why mainframe clients rely on agile practices
to deliver rapid business value
By Sol Lederman

D

evOps tools, processes and
new ways of thinking are
paving the way for clients
to drive innovation. A number of
questions face us on this path:
* How can legacy applications
running on the IBM Z* platform
fit into the DevOps way of
thinking?
* Are the tools and processes to
create a lean and agile DevOps
pipeline available to IBM Z
clients?
* Why is modernization important
and how do we get there?

DevOps Defined
The term "DevOps" is associated
with terms like "cloud computing," "scalability," "Linux," "open
source," "development pipeline,"
"containers," and "agile" and "lean

development." But, those terms
don't explain what DevOps means
or why it matters.
Rosalind Radcliffe, IBM Distinguished Engineer and chief
architect for DevOps and CLM for
Enterprise Systems, provides a
definition businesses can relate to
(ibm.co/2OAkEch). She describes
DevOps as "agile and lean brought
together to provide visibility and
transparency in the organization
to automate everything you can
possibly automate to allow the
delivery of business value at the
speed business requires today."
From a different perspective,
we can describe DevOps as the
combination of development and
IT operations through tools and
processes (the DevOps pipeline) to
shorten the software development
lifecycle to deliver features, fixes

and updates quickly.
The "speed business requires today" that Radcliffe described is accelerating. Development tools are
advancing rapidly. Release cycles
are getting shorter. The pressure
to develop, debug, test, release,
and deploy quickly is increasing.
Barry Baker, IBM Z and
LinuxONE* vice president, Offering Management, makes the business case that DevOps is important
for "delivering value to the business on a much more rapid scale,
much more frequently with higher
quality and doing that right with
an automation perspective, and
potentially with fewer resources."
The consequences of not embracing DevOps, according to Baker,
include being slower to deliver
software, being less responsive to
business needs, and increasing
