3. Information Technology
The Pressure on IT
Must reuse existing assets
…not designed to collaborate
Must show rapid, measurable ROI
Can’t introduce operational risk
…IT Bound By Constraints
Develop new products and services
Speed business transactions
Comply with governance
Integrate acquisitions
Outsource business functions
Business
Demands Change…

6. Introducing SOA
An Approach For Building Agile and Flexible Business Applications
Loosely coupled systems = loosely coupled (flexible) business processes
SOA Is Not:
A product or application
A specific technology
A specific standard
A specific set of rules
SOA-1: Fundamentals of Service-Oriented Architecture

7. Service Implementation
Service Provider
It’s all about Services…
Accomplishes A Defined, Self-Contained Unit Of Work
Does not depend on the state of other process/functions
Internal Details Hidden
Programming language
The execution logic
The data store (if any)
Exposes An Agreed-Upon Interface
Stable- built to last!
Service Interface
Service Implementation
Data
Service Logic
SOA-1: Fundamentals of Service-Oriented Architecture

8. Service Contract What Service Operations Are Available
Terms And Conditions For Service Requestor
What Service Operations Are Available
The input & output messages supported by each operation
The data representation model of each message's contents
Rules/Policies For Using The Service
Quality Of Service Aspects
SOA-1: Fundamentals of Service-Oriented Architecture

9. Implementing Service Contracts
Some possibilities…
Hardcopy Specification
Shared XML Schema
Representational State Transfer (REST)
HTTP Get/Post/Put/Delete and XML
Web Service Description Language (WSDL)
Available business methods (“operations”)
Message structure (data fields, types)
Bindings for operations (SOAP over HTTP)
