their environments. In a survey of
95 z Systems clients conducted in
2016, 68 percent now have Java
on IBM z* in production. Of those,
more than 80 percent described
the project as successful or very
successful.
"Java allows clients to enjoy
the qualities-of-service of
the z Systems platform while
leveraging broadly available skills
to develop applications that are
tightly integrated and coupled to
the core system-of-records on the
mainframe," Mitran says.
This offers many advantages,
including:
*

*

*

Significantly simplifying the
operational environment
for improved resilience and
better security
Streamlined applications
so they can be managed
within a single footprint on
z Systems
Improved response time from
consolidating and integrating
the workload

Java on
z Systems
demonstrates
about a

1.5x
performance
adventage over
alternative
platforms

IBM Competitive Project Office
internal tests have found with IBM
z Systems Integrated Information
Processor and special mobile and
cloud pricing, Java on z Systems
can provide 16 to 67 percent
better total cost of acquisition
compared to similar solutions
where the application sits
off-platform.

Clients See Success
IBM has been committed to
Java on z Systems for more
than a decade, focusing on

performance improvements
to the core Java Development
Kit, and co-design of z Systems
hardware and IBM Java VM (JVM)
technology. A large proportion of
new instructions and hardware
facilities introduced in the last
four generations of the z Systems
process were co-designed with
the IBM JVM team, Mitran notes.
As a result, Java on z Systems
consistently demonstrates about
a 1.5x performance advantage
over alternative platforms (bit.
ly/2pb3m5w).
Looking to continue to
have strong customer service
levels as its client base grew, a
software and IT service provider
looked to Java to help improve
performance. After shifting from
a distributed system to Java on
z/OS, the company noticed better
performance, with improvements
in database response by more
than 5x during peak periods.
"This is a great testament to the
value proposition of integrating
the Java workload with the system
of record and transactional
environment," Mitran says.
Because Java is integrated and
available across the middleware
portfolio, clients can easily
leverage the language with their
existing systems. For example,
German-based banking IT
provider Fiducia & GAD IT
AG uses IMS for transaction
procession in their core-banking
infrastructure. Fiducia & GAD
wanted to take advantage of Java
for the business logic running
inside IMS.
"By doing so, Fiducia &
GAD is getting the best of both
worlds-the infrastructure
and the qualities of service
of mission-critical z Systems
middleware like IMS, while
leveraging the modern ecosystem
and capabilities of the Java
language," Mitran says. "Java
in IMS gives Fiducia & GAD a

means for quickly and effectively
developing simpler and more
robust solutions to meet the needs
of their clients while leveraging
new skills and new ecosystems."
Improvements are also seen
when applied to other batch
and transaction processor
environments, including
WebSphere, DB2 and CICS. (Read
an example of how Java can be
used in CICS in "Create a DevOps
Pipeline for Java Applications in
CICS" at bit.ly/2o0wEpW.)

Looking Forward
Modern skills are an important
part of the Java value proposition.
From DevOps to API enablement,
mobile, cloud and beyond, the
popular programming language
is a way for clients to position
themselves for the future, giving
them the choice on how to
maintain and grow their IT assets.
With Java on z Systems, modern
tools and ecosystems can be
brought to the platform.
Because it's a mature
language, Java is familiar
to a broad base of seasoned
application developers with an
appreciation for enterprise and
mission critical computing. This
gives z Systems clients more
options and flexibility when
hiring and recruiting talent, and
gives developers more flexibility
when working with z Systems.
Java is ultimately about choice,
Mitran stresses.
"Java on z means clients now
have a choice in how they want
to address business problems,"
he explains. "They can leverage
their existing workforce and
their existing skills, but they also
have the ability to bring in new
skills and a broader workforce
where necessary. Java means
clients have the freedom to solve
business problems with the tools
they think are best and most
appropriate."
