Throughout the history of the IT industry, integration has been an important part of most projects. Whether it is integration of transactions, data, or processes, each has challenges and associated patterns and antipatterns. In an age of mobile devices, social networks, and cloud services, and big data analytics, integration is more important than ever, but the scope of the challenge for IT projects has changed.

Partner APIs, social networks, physical sensors and devices, all of these and more are important sources of capability or insight. It is no longer sufficient to integrate resources under control of the enterprise, because many important resources are in the ecosystem beyond enterprise boundaries. With this as the basic tenet, we address these questions:

• What are the current integration patterns that help enterprises become and remain competitive?
• How do you choose when to use which pattern?
• What is the topology for a “composable business”?
• And how do you accelerate the process of implementation through intelligent choice of supporting integration middleware?
