What is Service-Oriented Architecture (SOA) ?

SOA is different things to different people:

• a set of services that a business wants to expose to their customers and partners, or other portions of the organization

• an architectural style which requires a service provider, requestor and a service description

• a set of architectural principles, patterns and criteria which address characteristics such as modularity, encapsulation, loose coupling, separation of concerns, reuse, composability

• a programming model complete with standards, tools and technologies such as Web Services

• A set of standards

IBM Software Group


SOA Defining Concepts Universal Connectivity: Integrates most diverse environments, bridging protocols, languages, platforms, APIs and messaging paradigms – providing scale and scope of integration required by today’s extended enterprise

Service Orientation:

Facilitates loose coupling between

software components

Incremental Integration: Start small and plug in

capability to enrich your implementation as needs

dictate

Open, standards-based: Open APIs and protocols support the interoperability and substitution of middleware from multiple vendors

Event Orientation: Decouples applications that publish business

events from subscribing applications

Flexibility: A variety of options for

persistence, reliability, security,

availability...Deploy where

required, manage centrally

IBM Software Group


What’s Different about Web Services?Haven’t we heard this before?

• Structured programming and modules?

• Message Passing/Driven Systems?

• Remote Procedure Calls?

• OO Languages?

• CORBA, Distributed Smalltalk

• J2EE

This time we really mean it. No kidding.

If you can’t take a joke, you shouldn’t be using distributed systems.

There are some differences• Microsoft supports this model

• XML is more language and implementation agnostic.

• WSDL, WS-Interop include RPC and Messaging from day one;One is not added to the other.

• XML and WSDL is more forgiving of change in messages and evolution of interfaces.

• Common model for “services/impls,” “data in DB,” “data in flight.”

Simplifying Development

This is crazy. Programmers want to build a “part” that implements a “basic

building block” and then aggregate them together

Led the specification and implementation of several key standards (* work in progress)

• Modeling – UML 1.x, UML 2.x and various profiles

• Metadata – MOF 1.x, MOF 2.x, XMI and various metamodels

• Software Reuse and Asset Management - RAS 2.0

• Data Warehousing – CWM 1.0

• Legacy Integration/Re-engineering – KDM*

• Business Modeling (BPDM*) and Business Rules (BSBR*, PRR*)

• Ontology (ODM*)

• Middleware Interoperability – CORBA IIOP (J2EE™)Domain Standards (LSID – Life Sciences…)Focus : Integration of Modeling and SOA Standards

Implementing Patterns

Patterns may be implemented as process guidance or may be codified within tooling

The solution described by a pattern may be implemented in a component, or across several components, or in a service. There are various codifications of patterns.

creates(later)

uses

customizes an asset

The codified pattern may be further customized by less skilled users.

• Configurable Component: parameterized software component implementing one or more patterns; may be published as a service

• RSA Transform, Pattern: implements a pattern through actions which modify model elements and other artifacts

• Template: contains sections marked for substitution with parameters supplied by the user

Rational Software Architect: Patterns

“Pattern-apply” experience is highly interactiveEvolution of previous generations of pattern

mechanism experiences“Pattern-authoring” experience provides

flexibility using Open APIGOF design pattern contentAdditional patterns provided via RAS repository

on developerWorks• Examples: SOA / Web Service design patterns, J2EE

patterns etc

• Pragmatic example of applying MDA Transformations

• Example : Enterprise Patterns on Developerworks

New patterns view providing outline and

description of the pattern

Pattern rendered as a collaboration to

support incremental application

Support “drag-and-drop” of pattern

parameters into the collaboration

Impact:• Leverage existing skills and assets• Basis for asset-based development practice

Summary

SOA and MDA are mutually reinforcing.

OMG compliments W3C and OASIS• W3C and OASIS focus on SOA interoperability

• WS-* protocols and formats• WSDL and WS-Policy for interface definition and tool interoperability

• OMG defines the “tool flows”• Modeling (UML)• Rules• Meta-models; Processes• Legacy Modernization• Domains/Verticals

Challenges• Domain/Vertical support in “SOA”• Need to improve the “mapping” between SOA and UML• Modeling IT infrastructure, Security, etc.• End-to-End Policy and Rules• Seamless hand-off from development tools to systems management products• Application development IT Management “meta-model and process”
