A

Modern
System

IBM midtier solutions exploit API and microservices
to drive innovation

he app economy has
transformed banking.
In-branch transactions
have dropped by more than a
third since 2009, according to
data reported by consultancy
Bancography in Financial Times
(bit.ly/29yQ5gk).
This reduction in visits to physical locations has resulted in lower
operating costs because smaller
and fewer branches are needed
and because a mobile transaction is cheaper than one done in
branch, the article states. Because
of this, banks are investing in digital banking. In the past decade,
as smartphone use has increased,
so has mobile banking.
Banks today participate in an
API economy, partnering with
e-commerce vendors, insurance
companies, car dealers, home
realty companies and e-wallet
providers, to name a few.
India, with over 1.2 billion
people, is looking to go cashless

T

by introducing Universal Payment Interface, a
system that provides a unique identifier, such as an
email address, for every account participating in
an electronic transaction. Blockchain technology is
helping enable a modern payment architecture in the
financial technology space that supports real-time
settlements, avoiding the need for a central counterparty, according to CFO magazine (bit.ly/292HPFW).

TAKEAWAY
s The app economy is driving a need for
a modern midtier that serves data from
and feeds transaction requests into
a system of record emanating from a
system of engagement.
s !S MOBILE DEVICES HAVE LIMITED #05

7EB3PHERE E8TREME 3CALE RESULTS ON
CACHING FOR A QUICKER RESPONSE TIME AND
A LOWER TOTAL COST OF ACQUISITION AND A
SIMILAR EXAMPLE CAN BE FOUND IN OTHER
industries.

These innovations are driving
a need for a modern midtier (i.e.,
systems of integration) that serves
data from and feeds transaction
requests into a system of record
(SoR) emanating from a system of
engagement (SoE).

It's About
Microservices
Banks provide sophisticated enduser services built by combining
results from different applications. A majority of these services
aren't built in a monolithic way
but are rather componentized
via API-based access to data
and business services, meeting
demands of agile development
and mobile deployment.
Mobile devices have limited
CPU and memory bandwidth,
so applications use lightweight
representational state transfer
(REST) services-which are HTTPbased with uniform resource
identifiers pointing to a domain
