Conventional wisdom of the "software stack" approach to building applications may no longer be relevant. Enterprises are pursuing new ways of organizing systems and processes to become service oriented and event-driven. Leveraging existing infrastructural investments is a critical aspect to the success of companies both large and small. Enterprises have to adapt their systems to support frequent technological changes, mergers and acquisitions. Furthermore, in a growing global market, these systems are being called upon to be used by external business partners. Technology is often difficult, costly and complex and without modern approaches can prevent the enterprise from becoming agile.

Enterprise Service Oriented Architectures helps readers solve this challenge in making different applications communicate in a loosely coupled manner. This classic handbook leverages the experiences of thought leaders functioning in multiple industry verticals and provides a wealth of knowledge for creating the agile enterprise.

In this book, you will learn:

• How to balance the delivery of immediate business value while creating long-term strategic capability

• Fundamental principles of a service-oriented architecture (find, bind and execute)

• The four aspects of SOA (Production, Consumption, Management and Provisioning)

• How to recognize critical success factors to implementing enterprise SOAs

• Architectural importance of service registries, interfaces and contracts

• Why improper service decomposition can hurt you later rather than sooner

• How application design and integration practices change as architects seek to implement the "agile" enterprise
