The emergence of the Enterprise Service Bus (ESB) over the past two years has spurred the deployment of componentized applications based on a Service Oriented Architecture (SOA). SOA enables the development of business systems and processes with loosely coupled components (often called services) facilitating business agility. Much of the industry's focus has been on the architecture of the underlying ESB infrastructure that supports an SOA. Standards adoption has made it easier to learn new tools, but basic ESB infrastructure improvements haven't significantly reduced the effort involved in deploying and managing new business processes. That's because an ESB is simply a platform that unifies the advantages of multiple previous generations of middleware. This article illustrates that a comprehensive model for service components - the application-level modules wired to... (more)

Scaling Enterprise SOA Deployments

The first wave of integrating storage, computing, and networking hardware helped businesses move from client/server to Internet-based peer-to-peer networks. A second wave of integrating applications on top of the hardware infrastructure promised to deliver unprecedented economies of scale. In today's enterprise IT model, applications exposed as services need to be integrated seamlessly with other applications distributed across the network to generate the best operational efficiencies. Messaging-oriented middleware is at the heart of enabling seamless or "effortless" integration ... (more)
