What is SOA? Is it real or hype? Why are customers adopting it What is the impact? (Business, Technical,

Individuals) Who is doing it? When and where can we learn more?

SOA Fact and Fiction…

Everyone is using SOA FalseSOA can only be done using Web services FalseSOA offers cost savings and efficiencies because it’s a framework for

software reuse FalseOrganizations that rely on SOA are more agile then ones that don’t TrueSOA requires significant new investment in technology FalseSOA requires an Enterprise Service Bus (ESB) to be successful SometimesSOA is a technology innovation that is only concerns the IT department False

Industry Definition of Service-Oriented Architecture

A service is a function that is well-defined, self-contained, and does not depend on the context or state of other services.

A service-oriented architecture is a collection of services. These services communicate with each other, e.g., simple data passing or two or more services coordinating an activity.

SOA characteristics and principles:- Loose Coupling- Location Transparency- Protocol Independence

SOA What?


… a service?

A repeatable business task – e.g., check customer credit;

open new account

… service oriented architecture (SOA)?

An IT architectural style that supports

integrating your business as linked

services

SOA What Does That Mean?

SOA enables…

Business flexibility Reduce cost Investment protection

"Anything that changes can do that much better if the system is architected in SOA.”

Gartner

Improve customer-focused, go-to-market areas

Restructure and extend the enterprise

Increase effectiveness and efficiency of core functional areas

Top Innovation Priorities:

78% of CEOs believe integrating business and technology is fundamentalfor innovation

SOA What?


Service Oriented Architecture

A Service-Oriented Architecture is an enterprise-scale IT architecture for

linking resources on demand. These resources are represented as

business-aligned services which can participate and be composed in a

value-net, enterprise, or line of business to fulfill business needs.

The primary structuring element for SOA applications is a service as

opposed to subsystems, systems, or components.

Drive down costeliminate duplicate systems,

build once and leverage, improve time to market

Provide a flexible business model

react to market changes more quickly

Increase revenueCreate new routes to

market, create new value from existing systems

Reduce cycle times & cost for external

business partnersmove from manual to

automated transactions, facilitate flexible dealings

with business partners

Integrate across the enterprise

integrate historically separate systems, facilitate mergers and acquisitions of

enterprises

Reduce risk and exposure

improve visibility into business operations

Common business challenges demand the fusion of business and IT that SOA enables and each represents an SOA value proposition.

SOA What?


Customer Business Issues

Multiple versions of the truth- Inability to understand and tailor customer interactions- Inability to collaborate effectively with supply chain- Difficulty in complying with information-centric regulations

Need to do a better job leveraging information - Not using demand signals to drive supply chain- Not using customer analysis to tailor marketing and sales- Not leveraging sources of unstructured information

Don’t have trust in their information- Asking the same question in different places produces different

results

Don’t feel like they have control over information- No way to understand or control how information is used- No governance of sensitive information on customers or accounts
