SOA is like an orchestra


SOA: it’s in the eye of the beholder

“I actually have no clue, but we / you should buy it” kind of consultant or analyst (or manager ;-) )

SOA Definition #1

“SOA Is a collection of things that work with other things without knowing much about the other

things with the purpose of getting something from the other things. In SOA you can also have bigger

things to communicate with other little things to achieve bigger things.”

http://www.webservices.org/index.php/weblog/website_editor/arriving_at_a_definition_of_soa


SOA Definition #2

"A service-oriented architecture (SOA) is the organizational and technical framework that

enables an enterprise to deliver self-describing, platform-independent business functionality and

make it available as building blocks of current and future applications.“

SOA Definition #3

“In Service-Oriented Architecture autonomous, loosely-coupled and coarse-grained services with

well-defined interfaces provide business functionality and can be discovered and accessed

through a supportive infrastructure. This allows internal and external system integration as well as the flexible reuse of application logic through the composition of services to support an end-to-end

business process.“

Key principles of SOA

Services in a SOA represent independent business functionality reusability are loosely-coupled use open standards interoperability are well-defined (service contract) can be composed and orchestrated

Web Mashup Stylesby Dion Hinchcliffe

Mashup applications definition

Mashup applications quickly combine services and underlying applications from potentially many sources in- or outside the organization to create composite frontend

applications.


CONNECTING THE DOTS

SOA + Mashups


Do you see it?

SOA Mashups

Mashup applications quickly combine

services and underlying applications from potentially many

sources in- or outside the organization to create composite

frontend applications.

A service-oriented architecture is the

organizational and technical framework that enables an enterprise to deliver self-

describing, platform-independent business

functionality and make it available as building blocks

of current and future applications.
