Web Services, Service-Oriented Architectures, and Cloud Computing is a jargon-free, highly illustrated explanation of how to leverage the rapidly multiplying services available on the Internet. The future of business will depend on software agents, mobile devices, public and private clouds, big data, and other highly connected technology. IT professionals will need to evaluate and combine online services into service-oriented architectures (SOA), often depending on Web services and cloud computing. This can mean a fundamental shift away from custom software and towards a more nimble use of semantic vocabularies, middle-tier systems, adapters and other standardizing aspects.
This book is a guide for the savvy manager who wants to capitalize on this technological revolution. It begins with a high-level example of how an average person might interact with a service-oriented architecture, and progresses to more detail, discussing technical forces driving adoption and how to manage technology, culture and personnel issues that can arise during adoption. An extensive reference section provides quick access to commonly used terms and concepts.

efforts in your industry. Use an ESB Many organizations are also likely to use an enterprise service bus (ESB). If your organization is planning to use an ESB, then the previous experiment can be modified to include one. Figure 11.4 shows the use of Web services with an ESB to exchange data between internal systems. Figure 11.4 Using Web services with an ESB to exchange data between internal systems. The intent of this experimental project is to gain appreciation of the issues related to
Things Are Not Going as Planned? The example development illustrated in Figure 11.7 addressed the design-related restraining forces for adopting an SOA. Those design issues appeared in the force field analysis illustrated by Figure 6.9 and are as follows: Deciding what data to route Delays getting data updates distributed Deciding what data to warehouse Delays in getting data to the warehouse Redundancy of data Data quality issues Effects on operational systems for up-to-the-moment data
