Getting Started with Web Services, Service-Oriented Architectures, and Cloud Computing
In this part of the book, the focus shifts to getting started with Web services, service-oriented architectures, and cloud computing. Chapter 11 provides three basic experiments that use Web services and then uses the story about C. R.’s business trip to address more advanced uses of Web services. It ends with a vision of what Web services might mean for the future. Chapter 12 provides design concepts and considerations along with staffing and change issues to take into account when establishing a service-oriented architecture. It illustrates how properly designed service interfaces can make it easier for an organization to respond to the chaos of modern business. It ends with discussion of governance. Governance is important given the likely expansion of services within an organization and the growing use of services external to an organization. Chapter 13 discusses a way to evaluate external services and the systems and hardware that support those services. Chapter 14 summarizes the Web services, service-oriented architectures, and cloud computing related to the business trip described in Chapters 1 and 2.
