What is SOA?
 Loosely coupled modular services to support both
business and IT requirements.
So what does that mean?
Document number
3
Loosely coupled
 Services are independent. They don’t know or care whether the service is:
– Running on Windows, J2EE or a Mainframe
– Written in assembler, C, Java, or COBOL.
– Running on a machine in the U.S., India, or China
– Being served by a CRM system, a DDA system, or a database
 So what does that do for me?
– Enables a myriad of different (legacy) systems to supply information in a consistent
way using SOA.
Document number
4
Modular
 Services are no longer monolithic applications, but broken into compound and
granular services.
 Example: Initiating a transfer is a compound service, that might comprise the
following granular services:
– Find customer
– Authenticate customer
– Find all accounts and balances (for display)
– Find account (the funding account)
– Get account balance (to verify availability of funds)
– Find account (the receiving account)
– Debit account (the funding account)
– Credit account (the receiving account)
– Find all accounts and balances (for re-display)
Document number
5
So what does modular do for me?
 Note that in the previous example we reused a number of services within the
compound service.
 Other compound services will reuse these services as well, driving consistency (=
lower risk), lower cost, and flexibility.
Document number
6
SOA is an IT architecture consisting of loosely coupled modular services to
support both business and IT requirements.
 Loosely coupled: runs on a myriad of applications, systems, platforms and locations
to tie together new and legacy systems
 Modular: broken into compound and granular services to enable reuse
 Business and IT: across the entire organization.
Document number
7
SOA from a technical viewpoint
 Today SOA is used to broadly define a set of products and services that range from data
conversion services, to portal tools, which is why it is very difficult to answer the question, “Do you
use SOA?” A map of SOA components on the next slide should clarify.

Banking Examples of SOA
Registry and Repository: Find
Stop Payment Service, Charge
Fee service
Manage and monitor
Security: Authenticate user
Internet Banking
Business Process: Stop Payment
ESB: Routes to appropriate core system
Data Services
Business Logic: If
Customer_Status = Gold
Service_Fee = $8 else
Service_Fee = $20
Fee database
Process Services
Orchestration:
DDA / Current Account

Web Portals
A Map of SOA Components

Web Portals provide a single user interface to multiple back end systems via a service oriented architecture and
HTML.

Portals can hold multiple service requests and display them in portlets.
– An example would be with internet banking displaying a customers
- banking products
- Investments
- credit card balance (from another LOB or monoline)
- mortgage information (from another LOB or monoline)

Business Process Management can be broken into three parts
 Design: Usually with graphical eclipse based tools
 Execute:
 Monitor: Make sure that SLAs are met.

OK?
Yes
 Features of Human BPM:
– It involves human interaction (such as scanning KYC information)
– It uses external processes such as Chex System.
– It can be used to standardize business processes and reduce operational risk.
Document number

Enterprise Service Bus (ESB) is the communication backbone of SOA.

It generally supports the following functionality:
– Message transmission, routing, queuing, and monitoring
– Synchronous, asynchronous, point-to-point, and publish/subscribe messages
– XML and SOAP messages
– Adapters to legacy systems

It also supports services which are called out in other modules:
– Data Services
– Process Services

What does SOA do for me?
 Enables abstraction of core systems for isolation and potential replacement.
 Enables efficient messaging and business processes from the front end channels.
 Enables reuse of common business processes for greater efficiency.

How do I deploy it?
 Channel driven
 LOB driven
 IT driven
Document number
25
Channel driven SOA is the most common
 A single channel can create an SOA for itself and then share it later….or not.
 Wide adoption across the bank isn’t guaranteed.
Document number
26
LOB driven SOA
 An LOB might need functionality that isn’t available without integrating multiple systems or creating
a new system to assist in a business goal.
Document number
27
IT driven SOA
 This is a pure plumbing play and is difficult to drive across the bank.
 Who pays for these projects?
Document number
28
National City Business Drivers
 Single view of the customer
 Customer Management Objectives (CMO) drive customer experience
– Call center
– ATM
– Statement messaging
– Branch
