Today, Web services are being portrayed as the building blocks for the EAI platform, whereas, in the last three-to-four years, J2EE-based application servers have been able to carve their way to the core of enterprise application integration (EAI) solutions for several small, mid-, and large-size companies. This article examines how J2EE-based application servers support Web services and how they tie into and enterprise's overall integration and Web services strategy, enabling companies to use service-oriented architecture for EAI. The myth... Service-oriented architecture-based Web services is a "total and complete" EAI solution by itself-i.e., a solution for all integration needs. The fact... Web services is not EAI in and of itself. Rather, Web services is just another technology that enables EAI, and it can significantly change the traditional point-to-point int... (more)

Straight-Through Processing and Orchestration of Web Services

One word can describe the current state within financial organizations as far as straight-through processing (STP) is concerned: confusion. In the current state of STP implementation in almost every financial institution, its scope is still limited and it targets only a portion of the underlying financial instruments and product and business lines, and requires a full development cycle for each product addition. This article presents a paradigm to achieve internal and external STP through the orchestration of Web services. We discuss the fundamentals of STP, introduce the concept... (more)

Security and the .NET FrameworkGrave danger awaits if your security isn't robust

Labeled as the coming nirvana for enterprise application integration and business-to-business (B2B) integration, Web services technology is nonetheless vulnerable to a wide array of security threats such as denial of service and spoofing. In this article, we'll review Web services security requirements, the factors that determine them, and how Microsoft's .NET Framework supports them. Web Services as Interfaces to Business Methods The common belief is that the security requirements of Web services are the same as those of a Web site. But this assumption completely underestimates ... (more)

Business Process Management & Web Services

The journey of business process management (BPM) from technologies such as document flow routing to service-oriented architecture (SOA)-based Web services has been a process of evolution rather than revolution. In this article, we'll discuss the convergence of Web services and business process management, how Web services alleviate some of the core problems with BPM, and how Web services can help companies evolve into process-based organizations leading to increased efficiency and lower operational costs. It's all about processes, after all. Business process management (BPM) enables... (more)

Web Services Monitoring and Performance Management

It's critical that service-oriented architecture (SOA)-based Web services solutions provide high-performance, reliable, extensible, scalable, and open standards-based communication and integration for both internal and external applications that can be easily monitored. To meet these goals, it's imperative that companies design their Web services correctly, check service quality, conduct active performance management, and continuously monitor the end-point integrity of Web services. This article discusses monitoring and optimizing the design and runtime performance of Web service... (more)
