Accounting for the

FUTURE
Bankwest modernizes its mainframe integration environment
with a RESTful API framework and Java
By Jim Utsler k Photography by Ian & Erick Regnard

C

ompanies know they don't
operate in a vacuum. This
is perhaps most evident
in the banking industry, as the
Perth, Australia-based Bankwest
is very aware. Competition in this
space is fierce, and any missteps
can result in a hit-the-bricks
customer mentality.
That's why Bankwest has put
several modern customer-facing
technologies in place, including
mobile and online, to make it
easier for its customers to do
business. This directly aligns with
Bankwest's purpose: helping
people achieve what matters today,
and for generations to come.
Legacy back-end systems
can be an impediment to
efficiently extending these
offerings, however, creating a
level of complexity that may
slow time to market and hinder
the implementation of future
technologies.
According to Kevin Kilroy,
senior IT specialist, Bankwest,
this was the case at his
organization. As he puts it, "If we
can't adapt at speed, we can very

easily be disrupted by more
agile startups."
Realizing its middleware-based
approach to data transfers was
holding it back, Bankwest tasked
its core engineering team with
simplifying the stack to find
ways to allow front-end apps
to integrate directly with the
company's core mainframe-based
banking system. This resulted in
what the company calls Prime
2, a simple, lightweight suite of
mainframe-based RESTful APIs
that are directly accessible by
modern web apps and mobile
clients.
"This enables us to focus on
delivering superior customer and
user experiences. We've reduced
software layers and duplication,
our infrastructural footprint
and time to market for solutions
to be developed, while also
modernizing our technology by
using Java* on the mainframe,"
Kilroy says.

Back-End Complexity
A division of the multinational
Commonwealth Bank of

Australia (CBA), Bankwest has a
presence throughout Australia.
It specializes in both retail and
business banking, including
checking and savings accounts,
credit cards and loans.
Although it does share some
of its basic computing resources,
such as payroll, with CBA, it's
largely autonomous when it
comes to developing its own
IT solutions, including mobile
and online services and its core
banking system, which currently
runs on an IBM z Systems*
zEnterprise* BC12 (zBC12).
Developed 20 years ago using
PL/I, this system "was the first
real-time banking system in
the world to use a relational
database," Kilroy says
A number of upstream and
downstream channel systems-
online banking, contact center,
mobile, risk management,
lending processing, brokers and
payments-had been developed
throughout 20 years, using a
range of integration technologies
and middleware techniques,
which led to duplication of effort
