Questions You Need to Consider

What is Service Orientation and SOA and why is it important for your business?

Is it real? Are customers really using it today?

What are the core elements brought together under SOA?

How can IBM help you get started and deploy?

IBM Software Group

4

… a service?

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

open new account

What is …..?

… service orientation?

A way of integrating your business as linked

servicesand the outcomes that

they bring

… service oriented architecture (SOA)?

An IT architectural style that supports service orientation

… a composite application?

A set of related & integrated services that

support a business process built on an SOA

Traditional Business*

Today’s World-Class Business*

*Sources: CBDi

Economics: globalization demands flexibility

Business processes: changing quickly and sometimes outsourced

Growth: at the top of the CEO agenda

Reusable assets: can cut costs

Information: greater availability

Crucial for flexibility and becoming an On Demand Business

Why SOA for business flexibility and reuse?IBM Software Group

6

What are the barriers to business flexibility and reuse?

Lack of business process standardsArchitectural policy limitedPoint application buys to support redundant LOB needsInfrastructure built with no roadmap

IBM Software Group

7

As Patterns Have Evolved, So Has IBM

Flexibility

Point-to-Point connection between applicationsSimple, basic connectivity

Messaging Backbone

EAI connects applications via a centralized hub Easier to manage larger number of connections

Enterprise Application Integration (EAI)

Integration and choreography of services through an Enterprise Service Bus Flexible connections with well defined, standards-based interfaces

Service Orientated Integration

SOA builds flexibility on your current investments The next stage of integration

IBM Software Group

8

A programming model complete with standards, tools, methods and technologies such as Web services

Capabilities that a business wants to expose as a set of services to clients and partner organizations

An architectural style that requires a service provider, requestor and a service description. It addresses characteristics such as loose coupling, reuse and simple and composite implementations

Implementation

Architecture

Business

OperationsA set of agreements among service requestors and service providers that specify the quality of service and identify key business and IT metrics

Main SW vendors point of view

Oggi l’opportunità è utilizzare Internet per creare dei software molto più potentiincorporando un modello di servizi chesemplificherà il lavoro che le Direzioni IT e gli sviluppatori dovranno fare per fornire nuove capacità alle aziende

IBM Software Group

Gli standard aperti sonoestremamente importanti per noiperchè possiamo offrire delle scelteai nostri clienti. Se costruisciun’applicazione basandoti sustandard aperti questa puòcoesistere facilmente con altreapplicazioni costruite allo stessomodo. Se basi tutto il tuomiddleware su standard aperti puoiintegrare tipo ‘plug-in’ differenticomponenti insieme non necessariamente Oracle Fusion, ma anche JBoss oppure IBM WebSphere lasciando al cliente la scelta

Service Oriented Architecture è un accordo tecnologico di base, è unablueprint tecnologica, è un linguaggiotecnologico, è una grande blueprint. Noi ci crediamo. Noi pensiamo che i Web Services sono qui oggi, noicrediamo siano la prossima grandeidea. Cosa fa la SOA, trasforma le interfacce in testo. L’ultima volta chequesto è accaduto è stato con l’HTML, una grande rivoluzione che ha portatoal Web.

IBM Software Group

12


Il Management parla in termini di modelli, diprocessi, di attività di business specifiche, mentre le Direzioni I T parlano di tecnologiae di come questa possa essere integratanell’architettura complessiva.

Il risultato è un “gap” di capacità legato al tempo perso a tradurre i requisiti di business in sistemi IT. Questo approccio rischia diperdere per strada alcuni aspetti di processoimportanti. Nei mercati tradizionali questedeficienze possono ancora essere tollerate, ma nei mercati molto competitivi, il business non può tollerare questi ritardi e questamancanza di chiarezza.

Noi definiamo on-demand un’azienda i cui processi di business sono integrati end-to-end con i partner, i fornitori ed i clienti e possono rispondere con prontezza a qualsiasi richiesta dei clienti, opportunità del mercato, sfide esterne

Why SOA now?

To keep pace with global competition: “We are taking apart each task and sending it … to whomever can do it best, … and then we are reassembling all the pieces”

from Thomas Friedman’s ‘The World is Flat’

The standards and technology are finally in place, with broad industry supportAvailability of best practices for effective governanceThe necessary software to get started is available today

What are the benefits of service-oriented architecture?

Business benefitsBusiness flexibility provided by increased granularity of processes enabled through servicesAbility to quickly create business processes and composite applications to respond to changes in the marketplaceImproved customer service using services, without having to worry about the underlying IT infrastructure

IT benefitsBecoming a more responsive IT organization with a secure and managed integration environmentDecreasing development and deployment cycle times through the use of pre-built, reusable services building blocks.Reducing complexity and maintenance costs with common servicesEnhancing existing IT systems rather than replacing them

IBM Software Group

16

What differentiates SOA from claims like this in the past?

Broadly adopted Web services ensure well-defined interfaces. Before, proprietary standards limited interoperability

Standards

Business and IT are united behind SOA (63% of projects today are driven by LOB)*Before, communication channels & ‘vocabulary’ not in place

Organizational Commitment

SOA services focus on business-level activities & interactionsBefore, focus was on narrow, technical sub-tasks

Degree of Focus

SOA services are linked dynamically and flexibly Before, service interactions were hard-coded and dependent on the application

Connections

SOA services can be extensively re-used to leverage existing IT assetsBefore, any reuse was within silo’ed applications

Level of Reuse

21

Business process management is key to your SOAFlexible business demands automating and optimizing business processes

Identify and eliminate redundancies and bottlenecks

Reduce risk by gaining an understanding of process impacts prior to operationalizing

Automate process implementation, eliminating manual deployment tasks

Immediately execute new business rules and processes

Visualize actual process performance against key performance indicators

Pinpoint future process improvements

Without business process management, this would be achieved manually or through a dis-integrated set of tools from multiple vendors

HANDLING business events from disparate sources

What is an Enterprise Service Bus (ESB)?

Color = Data type

Shape = Protocol

Standard Life decoupled interfaces from their application...Turn this … …into this (web services).

Business applications and their interfaces become reusable

Decouples the interfaces from the business applications

The number and complexity of the interfaces is reduced

Rich business abstractions describe the application interface

But separate connection points still leaving bloated interfaces ….

The Enterprise Service Bus shrinks those interfaces further

RESULT Greater Business Responsiveness

Allows for dynamic selection, substitution, and matching

Enables you to find both the applications and the interfaces for re-use

Decouples the point-to-point connections from the interfaces

Turn this (web services)…

Enables more flexible coupling and decoupling of the applications

…into this (SOA)
