- Align IT with a health information exchange for SOA solutions by Jean Wang - [Clicks: 21]
Healthcare organizations are actively looking to Service-Oriented Architecture (SOA) for an IT solution to help transform the industry. But making sure the solutions delivered for these initiatives meet the needs of business users is challenging. Analyzing business vision and requirements and linking them to technology is the most essential step for SOA implementation. Using a health information exchange network as an example, this article illustrates a methodology and best practice of managing such requirements, using software tooling to ensure that the technology investment aligns with the business objectives during SOA adoption.

In previous four articles of this series (see "More in this series," upper-left), we used business analysis to identify business-relevant services ("Modeling SOA: Part 1. Service identification") that meet business goals and objectives. Then we specified services and use protocols ("Modeling SOA: Part 2. Service specification") necessary to meet IT objectives. Next, we provided design models for how the services are provided and used ("Modeling SOA: Part 3. Service realization," "Modeling SOA: Part 4. Service composition"). The result is a technology-neutral but complete design model of an architected services solution. In this final article in the series, we look at how to create an actual implementation that is consistent with the architectural and design decisions captured in the services model. We'll generate the platform-specific implementation by exploiting both model-driven development and the IBM® Rational® Software Architect UML-to-SOA transformation feature to create a Web service from the SOA model.

This third article of this five-part series explains how SOA-based Web services are actually implemented. The service realization starts with deciding what component will provide what services. That decision has important implications in service availability, distribution, security, transaction scopes, and coupling. After these decisions have been made, you can model how each service functional capability is implemented and how the required services are actually used. Then you can use the UML to SOA transformation feature included in IBM Rational Software Architect to create a Web services implementation that can be used in IBM WebSphere Integration Developer to implement, test, and deploy the completed solution.

Over the last few years, Service-Oriented Architecture (SOA) has received a lot of attention, bringing with it a new age of software development and business agility. However, SOA alone doesn't solve the world's IT problems. We still need solid and effective software engineering practises, as a poorly managed SOA implementation can go as wrong (if not more so) as any other architectural approach. This article presents a practical view to SOA, from both the technology and business perspectives, and presents a case study drawn from real-world experiences, showing the benefits that can be achieved through a successful SOA implementation.

Resiliency -- defined as the continued availability and performance of a service despite negative changes in its environment -- is vital in a Service-Oriented Architecture (SOA). An SOA infrastructure must ensure that a service is highly available regardless of unpredictable conditions, such as sudden and significant degradation of network latency, increase in database response times, or degradation of dependant services. This article, the first in a series that describes design issues and techniques for building resilient SOA infrastructures, focuses on how IBM WebSphere Application Server for z/OS factors into the SOA and how it contributes to SOA resiliency.

This series explores reusable assets such as recipes, software patterns, and models. The series shows how you can accelerate the development of SOA solutions. This fifth installment in the series explores the preferred data source pattern, which addresses consistency non-functional requirements when implementing reusable services. The preferred data source pattern is a microflow pattern for service aggregation. It was harvested from a real SOA engagement, and it has been reused in several other SOA applications and engagements. This article also demonstrates how you can use a Rational® Software Architect implementation of this pattern in a model-driven development environment to create a new service implementation.

Web services are a key ingredient of service-oriented computing and Service-Oriented Architecture (SOA). Interactions between service consumers and service providers are primarily message-based. The structure of these messages is defined in a service’s interface definition, specified in Web Services Description Language (WSDL). Organizations are increasingly moving toward supporting industry-specific messaging standards. This article describes an approach to developing a Web service that uses the ACORD messaging standard for an insurance industry client. With the help of an example, you can see how a Web service definition is created based on business process decomposition, including mapping data elements to their respective standard schema elements. You can also see considerations when dealing with schema maintenance, data binding, and data typing during runtime and build time. While this article offers only a glimpse into what is needed to fully utilize a standard message model, it tries to describe one key aspect of it and serves as a starting point for further discussion.

Service-Oriented Architecture (SOA) is at the heart of many business-transformation efforts. Many enterprises approach SOA transformation incrementally, using their valuable legacy IT systems to participate as service providers. The solution architect's challenge is not only to deliver the SOA infrastructure as a means to aid transformation, but also to ensure that enterprise-wide business operations remain robust and compliant. Your enterprise must develop an enterprise information-management strategy that can be part of the SOA and maintain overall data and content consistency across all business operations. Discover the challenges of such transformations, and review some design strategies to consider.

Books:- SOA Security in Action
by Ramarao Kanneganti, Prasad A. Chodavarapu - [Clicks: 32]
Anyone seeking to implement SOA Security is forced to dig through a maze of inter-dependent specifications and API docs that assume a lot of prior security knowledge on the part of readers. Getting started on a project is proving to be a huge challenge to practitioners. This book seeks to change that. It provides a bottom-up understanding of security techniques appropriate for use in SOA without assuming any prior familiarity with security topics. Unlike most other books about SOA that merely describe the standards, this book helps readers learn through action, by walking them through sample code that illustrates how real life problems can be solved using the techniques and best practices described in the standards. It simplifies things: where standards usually discuss many possible variations of each security technique, this book focuses on the 20% of variations that are used 80% of the time. This keeps the material covered useful for all readers except the most advanced.
