Building SOA composite business services, Part 1: Develop SOA composite applications to enable business services
Integrate existing SOA services by composing them in different ways. Part of our focus will be on how this is done within the framework of a Service Component Architecture. 		Articles 03 Oct 2006  
 
Building SOA composite business services, Part 11: Implement the subscriber entitlement process
The previous article in this series described, at a somewhat high level, how IBM WebSphere Service Registry and Repository and IBM WebSphere Process Server can be used for service consumption governance. This article describes the implementation details, showing how you can customize WebSphere Service Registry and Repository to support service consumption governance, implement the subscriber entitlement process using WebSphere Process Server, and integrate it with WebSphere Service Registry and Repository using its SOAP interface.

Building SOA composite business services, Part 10: Providing governance over service consumption using WebSphere Process Server and WebSphere Service Registry and Repository
Generally the focus of SOA governance has been on the service provider side, especially in terms of the service lifecycle. Very little attention has been given to the consumer or subscriber side. Who should be able to see or discover the relevant service endpoints? Or how can someone who has discovered a service send a request to consume the service? Or what is the process associated with authorizing access to the service? Answers to these questions vary from customer to customer. This article answers these questions in the context of a fictitious prototype composite application called Jivaro Bank, and it shows how WebSphere(R) Service Registry and Repository and WebSphere Process Server can be used to implement governance over service consumption and subscription.

Building SOA composite business services, Part 9: Business process parallel activities pattern for flexibility and configurability
This is the ninth installment of the series that addresses development of composite business services (CBS). A CBS can be composed from existing SOA services or created as a new service, designed for composability, or both. This article introduces a parallel activities pattern that is used to design Business Process Execution Language (BPEL) processes for CBS. The article provides a banking use case example of realizing the pattern to create a flexible and configurable business process in a simple application built from CBS. The article describes a solution to a realistic use case implemented by leveraging BPEL parallel activities. Multiple concurrent processes are instantiated such that the number of concurrent processes can be based on a variable, runtime-specified number of business objects. The article begins with a brief introduction of the parallel activities pattern, followed by a use case for a loan request in which you will learn how to use the parallel activities pattern to realize flexibility and configurability.

Building SOA composite business services, Part 8: Building multi-tenant portlets using WebSphere Portlet Factory dynamic profiles
This article is the eighth in a series that addresses the development of Composite Business Services (CBSs). CBSs provide the capability to integrate existing technologies and products to reflect desirable business intentions, such as configurability. IBM WebSphere(R) Portlet Factory is a portlet creation environment that simplifies and accelerates the development, deployment, maintenance, and re-use of portlets. This article introduces how to use WebSphere Portlet Factory to achieve configurability within the presentation layer by using dynamic profiles. 		Articles 21 Jun 2007  
 
Building SOA composite business services, Part 7: Supporting multi-tenancy for composite business services
Previous articles in this series introduced the notion of composite business services (CBS) and outlined some of the core elements of the deployment environment they required. Multi-tenancy is the capability to service multiple organizations (clients) from a shared, common hosting environment. This article describes the concept of multi-tenancy, and it describes the network-delivered approach to software-as-a-service. 		Articles 25 May 2007  
 
Building SOA composite business services, Part 5: Using IBM WebSphere Business Modeler
This article is the fifth in a series about developing composite applications to enable business services. Composite Business Services components are compliant with the Service Component Architecture and are developed using an integrated tool suite, which includes IBM WebSphere Business Modeler (WBM) and IBM WebSphere Integration Developer (WID). The runtime for the artifacts these tools generate is the IBM WebSphere Process Server. This article describes best practices for modeling, assembling, and deploying business processes using WBM V6. It also identifies some gaps in the integration of WBM and WID, and it describes some lessons learned during the example process modeling work, which is based on a real use case described in the article.

Building SOA composite business services, Part 4: Develop measurable composite applications with the Common Event Infrastructure
This article is the fourth in a series that considers the development of composite applications to enable business services. In order to determine if a composite application is meeting the stated business goals, the application needs to be measurable. This article examines how to develop measurable composite applications with the help of three reusable artifacts that are based on the Common Event Infrastructure. You can learn why the artifacts are needed and how to use them to measure a composite application. 		Articles 16 Feb 2007  
 
Building SOA composite business services, Part 3: Build consumable Web Services using the REST architectural style in WebSphere
This article is the third in a series about developing composite applications to enable business services. The article focuses on the Representational State Transfer (REST) architectural style. By using a facade component as a REST-style interface, existing SOAP-style Web services can support customizable URLs, multiple resource format representations, browser response caching, streaming of large attachments, and use of HTTP methods to manipulate the resource.

Building SOA composite business services, Part 2: Migrate business integration projects from WebSphere Application Developer-IE v5.1 to WebSphere Integration Developer v6.0.1
This article describes some of the issues and the solutions for migrating a prototype composite application from WebSphere Application Developer-IE v5.1 to WebSphere Integration Developer v6. We'll explore WSDL bindings, WSDL interfaces, XSD definition, and Business Process Execution Language (BPEL) coding. 		Articles 13 Dec 2006  
 
Make composite business services adaptable with points of variability, Part 2: Using dynamic service mediation in WebSphere Business Services Fabric
Explore options for building points of variability (POV) in Service-Oriented Architecture (SOA) composite business services in this series. A common requirement for POVs is to be able to easily change the behavior of a service, despite differences in client organization, processes, technology, or business relationships. IBM WebSphere Business Services Fabric (WBSF) lets you adapt service behavior based on the content of a service request, policies, service definition, and semantics. Read this article to learn how to bind, at runtime, a service invocation in a Business Process Execution Language (BPEL) process to one of several related endpoints by using ontology extensions and the WBSF Dynamic Service Assembler. A credit card scenario shows the implementation step by step. You walk through possible issues and explore the advantage of using WBSF compared with other Service Component Architecture (SCA) components (business rules, selectors, and mediation modules).
