SOA Concepts SOA Maturity Model and Progress Products Summary


Introducing SOA & SOBA

An approach for building agile and flexible business applications• Loosely coupled services

= flexible business processes

SOA is not A product or application A specific technology A specific standard A specific set of rules

Service-Oriented Architecture > Service-Oriented Business Applications


Loose Coupling – How Loose is Loose?

The less you know the better!! Just tell me the interface Little or no knowledge of language

or platform Web Services gets all of the hype,

but it’s not the only approach It doesn’t come for free

Key Concepts

Service Provider Service Requester Service Contract Service Infrastructure


Service Provider

Accomplishes a defined, self-containedunit of work • Does not depend on the state of other process/functions

Internal details typically hidden• Programming language• Execution logic• Data store (if any)

Exposes service via a service interface• Security• Service infrastructure• Context management• Object activation

May call other service providers

Service ImplementationService Implementation

Logic

Service Interface


Service Requester

Presentation layer or another service Locates service provider

through agreed upon service directory

Binds/invokes service based on service contract

Service adapter encapsulates all issues associated with accessing service

•Security•Service infrastructure•Context management•Service discovery

Fn()Fn()

Service Adapter


Service Contract

What service operations are available • Input & output messages supported by

each operation

• Data representation model of each message's contents

Rules and/or policies for using the service

QOS aspects

Terms and Conditions for Service Requester


Documenting Service Operations

Shared XML Schema Shared interface file Web Service Description Language (WSDL)

• Available business methods (“operations”)

• Message structure (data fields, types)

• Bindings for operations (SOAP over HTTP)

Hardcopy specification of one of the above
