AOTAOT LABLAB Service Oriented Architecture

Features

A baseline of concepts and principles and a strategic vision have emerged

Logical view A service is an abstracted, logical view of actual

programs, databases, business processes

Message orientation A service is defined in terms of the messages

exchanged between the parts

Description orientation A service is described by machine-processable

meta data

Granularity Services tend to use a small number of

operations with relatively large and complex messages

Platform neutral Messages are sent in a platform-neutral,

standardized format (XML)

Definition

There is no one recognized definition of SOA

SOA is an architectural style that supports service orientation

Service orientation is a way of thinking in terms of services and service-based development.

Problems

Rely on static syntactical description of service interfaces They guarantee services binding at

design time

Do not address service selection based on a dynamic assessment of nonfunctional attributes They guarantee syntactic

interoperability, but they fail to provide semantic operability

Open issues

How to efficiently discover Web services

Semantic annotations

Federations and peer-to-peer discovery

How to allow and facilitate their composition Semantic annotations Workflow technologies AI techniques

AOTAOT LABLAB SOA vs. JBI/ESB

SOA and ESB Are More Than Different Answers to the Same Problem ESB is designed assuming a world of horizontal

layers - such as database, application logic, … SOA is designed for a world of vertical slices through the IT infrastructure - such as ordering, fulfillment, billing, etc.

AOTAOT LABLAB SOA vs. JBI/ESB

JBI is a Java standard for structuring business integration systems along SOA lines. It defines an environment for plug-in components that interact using a services model based directly on WSDL 2.0.
