Business Pain Points

Globalizations: Competition from

geographies that have lower cost structures

Economic Pressures: Record cash

reserves but anemic growth

Business Process Outsourcing:

Outsource non-core capabilities

Regulatory Compliance: Must comply

to stay in business

Technology: New technologies thatprovide additional business capability

IT Investments: Investment in improving

IT efficiency, rather than creating new business

opportunities

IT Pain PointsGlobalizations: Business acting globally and

IT is an after thought

Economic Pressures: IT not generally

viewed as a differentiator

Business Silos: redundant infrastructure

and higher cost

Lack of Cohesive Business

Information Strategy across the enterprise

Governance & Organization for agility

Standards: At last count over 50 standard

bodies

Technology Refresh: Business reluctant

to upgrade to latest versions

Business and IT Pain Points

The ideal architecture representation of atypical current state does not cut it any more

Representation of theenterprise architecture of anhighly successful ITorganization (Complex andExpensive)

Enterprise are attempting toincrease revenue(cross sell orup sell existing customers) andreduce cost(especially IT)

SOA enables Enterprises to

achieve both these

objectives

Alternate vision is toconsolidate business processto applications provided by asingle vendor

SOA Definition and Objectives

SOA is the business operations strategy for leveraginginformation to meet their objectives, such as increasing overallrevenue, increasing customer satisfaction, improving productquality, etc.

To provide leadership in the industry by identifying the endcustomers and IT needs

Provide a roadmap for successful adoption of SOA

Identify important business and technology patters of SOA

SOA Reference Architecture The proposed end-state architecture

SOA Framework SOA Methodology similar to Enterprise Architecture Framework

Governance and Organizations Document various patters and best practices around governance

and organizations

Service Lifecycle Service definition, deployment and management process including

templates, best practices, patterns, etc.

Appendix Frequently Asked Questions (FAQs)

Intended Audience for the SOA

BlueprintBusiness sponsors of IT projects and IT leadership teamresponsible for SOA across the Enterprise or LOB

Enterprise Architects who shall be responsible for driving the

vision, roadmap and architecture or each of theseimplementations

The Program Management Office so that they can get a betterunderstanding of how to manage SOA initiatives

The Project teams so that they can get a better understanding of

how to map dependencies and develop a timeline that meetsbusiness expectations

The vendors who shall be providing the products and tools

Standards bodies so that they can get a better understandingwith use cases on how end users plans to leverage technology to

meet their business objectives

The three steps of SOA Lifecycle

1. Initiate SOA

Establish the process for getting started

Establish objectives, project teams, timelines, deliverables, etc.

2. Develop Roadmap

Establish SOA Principles

Develop Reference Architecture

Develop SOA roadmap based on business priority

3. Execute SOA Roadmap Initiate transformation Business and IT by establishing SOA

Governance

Manage Services Portfolio and execute roadmap

Revise and update roadmap on a periodic basis, based on internaland external environmental changes

Understand the SOA Maturity Model enablesenterprises to develop the roadmap toachieve Future Vision Following are the three stages

of SOA Maturity Model

Phase 1: Develop Web

Applicationsdemonstrate quick

wins to business by rapidly

deploying new business solution by

reusing services

Phase 2: Develop composite

applications such as single view of

the customer or automate integration

points between systems

Phase 3: Automate Business

Processes across the enterprise or

LOB

It is not necessary to exist one

stage to start the next

SOA Reference ArchitectureFuture

State Architecture For Version 1.0 the focus of SOAReference Architecture withthree major tiers for providingbusiness capabilities

Web Application Tier(sometimes also

referred to as the Presentation Tier)

provides the multi-channel web

presence for the enterprise

Service Tierprovide service lifecycle

management, service discovery and

composition capability. Also provides

services that cross application

boundary

Application Tiercontains the

traditional legacy or mainframe

applications and EAI


17/3417


Web Application TierPackaged Applications Industry standard core applications robust core business logic and data structure

Vanilla Implementation (limit custom changes)

Easier and cheaper to maintain

Easier and cheaper to upgrade or replace

Footprint Limited to the best of the breed

One standard Implementation Worldwide

Limitations of Packaged Applications

Modification of business process and user interface is not very easy

Most packaged applications are still based on proprietary technology

Difficult to find resources

Upgrades are expensive

Integration is not straight forward


18/3418


Web Application TierCustom Applications categories1. Develop a custom (web) application leveraging an Application Servers

2. Develop a custom (web) application leveraging a Portal product

3. Develop a thick client by either using tools based on open standards or proprietary

technology

Focus of this presentation shall be on option 1 & 2


19/3419


Web Application TierCustom Application Requirements Provide unified user experience across the web site

Standardize look and feel across all the sites

Create a single point to access all information

Provide only the information the user has access to

Provide a highly reliable, available and scalable environment

Provide user the capability to personalize their pages

Reduce operational cost / TCO


20/3420

SOA Reference ArchitectureWeb Application Tier: Custom ApplicationArchitecture Approach

Based on SOA that promotesre-use at multiple levels

Provides rapid delivery

capabilityLeverage each product forwhat it is good at, exampleportal for presentations basedon entitlements

Enable business to combinemultiple services to providenew capabilities

Loosely coupling presentationfrom the business logic makesit reliable and scalable

SOA Reference ArchitectureWeb Application Tier: Custom ApplicationFramework ComponentsFramework Components Description

Data Services, Logging, Exception Handling,

Applications Configuration, Monitoring

Standard framework components and most IT

organizations already have these components

Search Framework Service leveraged by the Presentation tier for

paginations

Notification Framework Leverage for any external notification such as eMail, IM,

SMS, etc.

Service Proxy Service proxy to EJBs, Web Services or any other

external service/protocol

Security Framework consisting of Authentication,

Authorizations, SSO, Identity Management, Auditing

Standard client security framework to integrate with

enterprise security service as well as develop custom

authorization modules for the applications

SOA Reference ArchitectureSOA Framework

Required to enable rapid development and consists offollowing layers

Transformation Layer

Business Logic Layer

Business Data Layer

Integration Layer

Reasons for an SOA Framework

Solid foundation for creating services Improved productivity

Utilize Off-the-self framework

Dont need to know the internals of J2EE or object-oriented design

SOA Reference ArchitectureSOA Framework

Business Benefits of the SOA Framework

Catalyst for adopting SOA

Consistent design and development process across all projects

Repeatability and the ability to guarantee a minimal level of architecture

and design rigor

Improved business agility as a result of having modular solutions that

can be changed easily (often via configuration changes)

Use of software engineering best practices amongst developers with

varying skill levels

More consistent, predictable and better tested solutions

Improved mobility of developers to move from one project to another
