ARTICLE: SYSTEMS MANAGEMENT
Why today's systems management demands a structured approach
ystems management has grown increasingly complex.
Business needs now dictate that mainframe and distributed
systems teams consult and work together on mission-critical
applications. This can be a challenge, as the platforms share data
and resources but have different management requirements.
The addition of new workloads-including private, public
and hybrid cloud applications-also adds to complexity. More
companies are using APIs to speed up creation of applications.
As a result, IT shops must strategize on how to incorporate
these technologies and workloads. Joseph Gulla, IT leader of
Alazar Press and a 28-year veteran of IBM, suggests a six-point
checklist to get a grip on managing these evolving systems.
(See "Challenges of Managing Technology Despite Increasing
Open standards. Companies should embrace open
standards to expand vendor and technology choices.
Open standards enable interoperability of systems from
different vendors. Open source also makes it easier to port
applications from one system to another.
Centralized management. Employing a common toolset
and procedures will help smooth
management. Centralized management reduces costs, offers scalability and prevents repeat mistakes.
Best-of-breed components. It pays to select the best
components for your system to prevent poor choices that
it easier to select components that will work together.
Test new technologies. Avoid the urge to apply new
technologies without any testing. Instead, use a pilot project
to test the technology and ferret out any problems before
the "new technology can have a disastrous impact on the
organization," Gulla says.
Write a business case. Preparing a business case can
help assess costs associated with hardware, software, labor,
migration and conversion. It's always a good idea to run a
Incorporate the old with the new. When adding new
technology, the goal should be to transform existing
systems rather than ripping and replacing them.
"Transformation solutions that are open, simple to use and
nondisruptive with vendor and community support are the
most desirable," Gulla notes.
