Abstract
Introduction
Retail banks have developed complex IT infrastructures which aren' t always
suitable to meet new demands in the changing competitive environment.
Datamonitor believes that banks require new application architectures that
will meet operational requirements for at least 10 years, allowing them to
amortize their investments and to first embrace and then leverage upcoming
technologies and trends.
Scope
*This report examines the reasons behind why retail banks throughout the world
are seeking to enhance existing application architectures.
*This report examines the application architecture strategies available to
retail banks, but avoids assuming a ' one-size-fits-all' approach will work.
Highlights
Banks are revisiting application architecture strategies in light of changing
operational requirements. Many of the world' s retail banks have
unintentionally created complex application ' landscapes' , often with a minimal
degree of integration and an over-reliance on ' silos' for specific
functions.
Legacy integration infrastructure struggles to deliver efficiencies in modern
retail banking. The transition to a customer-centric, multi-channel approach
represents a development where institutions must move to a more flexible and
streamlined integration architecture if they are to remain competitive.
Developing a seamless multi-channel experience for customers requires a fully
integrated infrastructure. SOA provides the most flexible and cost-effective
solution to achieve this aim. The combination of SOA-enabling future internal
IT infrastructure and the selective use of SaaS is an optimum application
architecture strategy for retail banks.
Reasons to Purchase
*Gain insight into the challenges faced by retail banks seeking to develop
their application architectures.
*Understand the technological evolution of application architecture and the
level of SOA penetration in the world' s retail banks.
*Gauge how market conditions are influencing application architecture
strategy, including the use of hybrid SOA/SaaS models.

Traditional integration methods
result in complexity, lack of scalability or expensive integration 10
Point-to-point integration creates costly complexity with multiple
applications 10
Hub and spoke integration is more manageable but suffers
from bottlenecks and a lack of scalability 11
Message bus architecture
allows a scalable solution but proprietary requirements make it expensive

The implementation of multi-tier
architecture has created problems for retail banks 13
Remedial action must

Go to Market 19
Understanding the appetite to invest in SOA 19
Vendors' go-to-market
strategies need to be refined for a more widespread uptake of SOA 19
Vendors need to develop more non-IT material for demonstrating the benefits of
SOA 20
Lower-pitched marketing material will help business management
understand SOA 20
Parallel systems that help demonstrate ROI will be
useful for IT management 20
SOA approaches customized to the vertical
market will help retail banks to differentiate between vendors 21
Recommendations 21
Have a SOA ROI model that is both accurate and easy to
understand 21
Banks will be interested in technologies and business models
that help stretch operating budgets 21
Ensure any discussion on
application architecture strategy has a distinct business flavor to it 22
