SOA Overview
Copyright © 2007 CA. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
Have you heard of SOA?
Copyright © 2007 CA. All trademarks, trade names, services marks and logos referenced herein belong to their respective companies.
What is Service Oriented Architecture?
> SOA stands for Service Oriented Architecture
 At least everyone agrees about that!
> No single definition
 More a methodology than a technology
> An evolution of component-based approaches

What is Service-Oriented Architecture?
> Attributes of SOA:
 Emphasizes reuse of existing applications
– Incremental, built on current investments
– Services can be “orchestrated” to build new applications or
address new requirements
 Expose interfaces to applications
– Implementation should be hidden from consumers of the
service.
– Standards-based

What is Service Oriented Architecture?
> Attributes of SOA
 Services aim to be loosely-coupled
– Independent of specific program languages or platform
– Resilient to change
– Limited dependencies between services
 Services support distributed computing
– Web Services represent the most common technology

WSDL, XML

.NET and Java are the most common platforms for
delivering web services
– But web services is not the only technology

What’s in the Plex SOA toolbox today?
> Plex is already capable of delivering web services and SOA
 Model-based design environment
– Encourages abstraction and interface-based design
 Java and .NET generators
– The “de facto” standard platforms for SOA implementations
– Rich set of service APIs
 COM and EJB Connector generation
 Websydian TransacXML
– XML document handling
– Web service creation and consumption

New Plex SOA Capabilities
> CA Plex r6.1 is currently in development
> Planned to include a new service creation feature
> Based on Microsoft’s Windows Communication Foundation
(WCF)
> What is WCF?

Endpoints
> Endpoint consists of three parts:
 Address: Where is the service located?
 Contract: What does the service offer?
 Binding: How do we communicate with the service?
