IBM Systems Magazine, Mainframe - May/June 2015 - L20

multi-tier model for today's Web
applications.
This architected combination
of devices running different parts
of an application are a good
fit for Linux under z Systems
servers. Even though these
application systems may not
have been developed to run on
the z Systems platform, now is a
great time to migrate them and
consolidate their monitoring
and management.
Another implementation of
this technology that is a good fit
is cloud services. A private cloud
service could be created by an
IT organization by designing
and implementing a Linux
technology-based cloud on the
z Systems platform. The timing is
right because all of the elements
needed to do this are available
today. IBM has done this with a
solution called the IBM Enterprise
Cloud System that provides the
capability to rapidly deploy a
secure, scalable OpenStack-based
Linux cloud environment.
Database and
Middleware Services
Today, many commercial
middleware products run
on Linux on z Systems. This
includes product families like
IBM WebSphere* software
that supports application and
transaction infrastructure,
application transformation,
business integration, commerce
and mobile solution support. IBM
Information Management and
IBM Tivoli products are also in
this Linux lineup.
There are a number of opensource
middleware projects with
distributions for Linux. Apache
Geronimo is an application server
that is used in the WebSphere
Application Server Community
Edition from IBM. DB Express-C
is a database server that IBM
makes available through the DB
20 // MAY 2015 Linux on z Systems
Express-C distribution. Eclipse
supports application modeling,
design, development and
application management and is
used in IBM Rational* and IBM
Rational Jazz.
Key Business Applications
The leader in propriety
application software that runs
on Linux is SAP. According to a
recent article in Forbes, SAP has
a 25 percent market share of the
$25 billion ERP marketplace.
SAP has more than ERP-it
is an impressive solution because
it covers so many business
functions under the umbrella of
its distribution.
What Does the
future hold?
Linux is growing in importance.
The world's largest enterprises
are increasing their investments
in Linux at double-digit rates.
Linux on z Systems is gaining
in use. Open source is growing
in importance, but don't count
out proprietary software as it
also has customer relationship
management (CRM), supply
chain management (SCM),
human resources management
system modules and others.
The SAP products have support
from Red Hat and SUSE. IBM
also has strong support for SAP
and, because Linux runs on IBM
systems like z Systems servers,
SAP benefits from running on IBM
hardware. SAP also benefits from
IBM's management and support
software and implementation
services from trained and certified
practitioners.
In addition to powerful
proprietary solutions from
companies like SAP, there
are hundreds of open-source
applications focused on
business support. Apache
Open For Business Project, or
Apache OFBiz, has ERP, CRM,
e-business, SCM, manufacturing
resources planning, maintenance
management, asset management
and point-of-sale support. OFBiz
has a long history of delivering
important functionality for a
variety of stakeholders.
It is tempting to write that
significant innovation is
happening mainly through
open-source projects but this is
not entirely true. Open-source
software is benefitting from
tough economic times and many
companies are using it to keep
costs down. However, opensource
projects are frequently
abandoned with only one in six
becoming successful. Software
projects for proprietary
software have a different set
of challenges and, despite
barriers, often deliver worldclass
software. Consider this
highly successful commercial
software that helped to create
an industry-z/OS*, CICS*, IMS*
and DB2*.
Joseph gulla is the it leader of
alazar Press. Previously, he was an
executive it specialist at iBm.
