Agenda

• SOA Maturity Model and Progress Products

Introducing SOA SOBA
Service-Oriented Architecture gt Service-Oriented
Business Applications

• 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

9
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 its not
  the only approach
• It doesnt come for free

10
Services In Action
Service Requester
Service Request
Service Response
Service Contract
Service Provider
11
Key Concepts

• Service Requester
• Service Provider
• Service Contract
• Service Infrastructure

12
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
• Stable, and built to last!

13
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

14
Service Contract
Terms and Conditions for Service Requester

• 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

15
Documenting Service Operations
Some possibilities

• 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

16
SOA Infrastructure

• Connects Service Requesters with Providers
• May be used to communicate with Service Registry
• A variety of technologies are available for
  implementation
• Technology choice impacts service coupling
