Objectives

How SOA enabled Business Application Modernization can help your organization achievegreater value from your existing application investments:

Set some context around the SOA enabled application modernization landscape

Look at the benefits of Business Application Modernization

Discuss how to leverage value from your existing assets, modernizing, simplifyingand Service-enabling Business Applications

Barriers to business flexibility and reuse

Application silos

Rats Nest of interconnections

Fragile and brittle coupling

Limited ability to trace data andchanges

Business logic / Processes andconnectivity logic intertwined

High cost / risk / skills needed to

change or add assets

In 2004, 73% of I.T. budgets werespent on maintenanceand 27% on

new investments.

In 2005, survey respondents expectto spend 76% on maintenance,leaving just 24% for newinvestments.

Some basic SOA terms

a service?

A repeatablebusiness task e.g.,check customer credit;

open new account

service orientedarchitecture (SOA)?

An architectural stylethat supports

integrating yourbusiness as linked

services

SOA impacts every aspect of IT and business.

SOA isnt just about re-using the assets you create tomorrow its also about re-using the assets you have today

Existing applications are among the most valuable assets acompany owns there will be a desire to leverage the core valueof investments made:

Support core processes and provide crucial information

Contain billions of lines of valuable business intelligence these are a key part of the functional DNA of organizations

Process majority of customer, product, supply chain andchannel data

Reusing proven, time-tested applications can significantly lowerrisk, cost and time to market

Best practices provide a framework for reuse and connectivity to abusiness policies and reuse as a design point for SOA

The value of leveraging legacy applications for ServiceOriented Architectures

Agility is a competitiveadvantage that one

company can not take

away from another

How do I discover programs and businessrules for reuse?

How do I deploy existing assets in a robust,flexible SOA environment?

The need to support agile

As knowledge of the system

Many older systems are often

left outdated and slowlydecreasing in business value HUGE investments left to rot

Modernizing legacy applications SOA Transformation

Using appropriate tooling and techniquesto accelerates SOA adoption, reducing

transformation costs, time and resources:

Extract business processes from existingapplications

Reuse existing components to buildservices consistent with the business

needs Automate the process, reducing cost, time

and resources needed

Extend mission critical applications as

services, leveraging their core value:

Avoid the need to move off existingplatforms or rip out legacy software

Legacy applications can be decomposed,rationalized and SOA-enabled

Renovate existing applications to be moreefficient, streamlined and responsive

Database Conversion

Non-Relational / Relational, Remediation

Application Conversion

J2EE Target, Migration, Web Enablement

Technology Upgrade

Language Environment, Operating Systems

Simplify

Dead Code Removal, Application Consolidation

Restructure

Code Modularization and Restructuring

Sample legacy transformation patterns for reuse

Fat client

Services candidatescan be embedded inthe inter-page logicand back-end bindings

Decompose multiple

page transactions intoflexible servicepatterns

Batch

Jewels of businessprocess locked away inmonolithic programs

Difficult to understand,document, enhance &

maintain

Opportunity tomodularize & integrateas services

Leverage the value of your mainframes

IBM System z servers are the most cost-effective

enterprise transaction servers for a mixed workload

Extending proven applications usually carries lowerrisk and lower cost, and is faster to production

Open and flexible, IBM mainframes potentially

reduce the cost, risk and time to value in meetingbusiness objectives

IBM is publicly committed to ongoing investments inthe mainframe as a core strategy

Mainframe applications typically support core

processes, contain billions of lines of valuablebusiness intelligence and are a key part of thefunctional DNA of organizations

Build an SOA around your core mainframe applications

Sixty-five percent of zSeries customers see the mainframe as the best platform for enterprise-wide IT*

IT executives strongly prefer to extend existing core applications, rather than undertake new application or

migration projects*

Leverage the value of your Midrange Systems

IBM System i servers have the highest

scalability in the industry ranging from thesmallest 515 to the largest 595 using the exactsame operating system

The overwhelming majority of System i accountsare entitled to tools like the Web Service Wizard

that can transform RPG and COBOL Applicationsinto web services in a single step

IBM System i Enterprise Edition clients areentitled to licenses of Workplace ServicesExpress to extend their SOA using a Portal

IBM System is virtualization environment can runjust about every workload clients have

Midrange applications typically support core anddistributed processes that are proven, reliableand have stood the test of time

Build an SOA around your core and distributed midrangeapplications

An Enterprise Service Bus (ESB) is a flexible connectivityinfrastructure for integrating services and applications

An ESB performs the followingbetween requestor and service

CONVERTING transportprotocols between requestor

and service

HANDLING business eventsfrom disparate sources

TRANSFORMING message

formats between requestorand service

ROUTING messages

between services
