Great Expectations: Can SOA Deliver?

Agenda

What is SOA?

Technical details

What does it do for me?

How do I deploy it?


What is SOA?

Loosely coupled modular services to support both business and IT requirements.

So what does that mean?


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.


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)


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.


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.


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


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)

Web Portals

A Map of SOA Components


Portal Example

Portlet to credit card company


Business Process Management can be broken into three parts

Design: Usually with graphical eclipse based tools

Execute:

Monitor: Make sure that SLAs are met.


Example of BPM: Open New Checking Account


Scan KYC Information

Run ChexSystem

Existing

Customer?

No

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.

Result

OK?


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.


Isolate this system by accessing only via data services and process services.

How do I deploy it?

Channel driven

LOB driven

IT driven


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.


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.


IT driven SOA

This is a pure plumbing play and is difficult to drive across the bank.

Who pays for these projects?
