Format: PDF / Kindle (mobi) / ePub
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.

An SOA using Web services. The discussion showed that by combining these integration techniques: n The standardization efforts related to the use of Web services are assisting other integration techniques. This was shown in the weakening restraining forces for adopting an enterprise data warehouse and for ORB middleware. n Because the use of Web services does not require abandoning existing systems or data storage, this further reduces barriers to the adoption of an SOA as part of an.
With the adoption of a serviceoriented architecture (SOA) with cloud computing can be a significant challenge. Chapter 7 showed that as technology and standards evolve, technical issues diminish, leaving the remaining restraining forces related to business, legal, and design issues. This chapter shifts the focus to human change issues. These issues most often manifest themselves in resistance to change. Forms of resistance and reasons for the resistance are discussed as well as ways to address.
Avoid using an off-the-shelf product or a cloud-based service. On a rare occasion it may be true, but most often it is just a means of resistance used by those who want to keep things as they are or to develop something new on their own. Loss of Familiarity, Competence, and Control Neuroscience research has uncovered information that explains a great deal about resistance. According to David Rock and Jeffrey Schwartz,4 4 David Rock and Jeffrey Schwartz, “The Neuroscience of Leadership,”.
Business process modeling notation (BPMN).3 The tool does not generate labels for the tasks. I have added task labels to this diagram. There are a couple of ways the generated diagram can give you hints that there are problems with the check marks in your decomposition matrix: This example is from the first edition of this book. The idea that a VPA—like the one in the story about C. R.’s business trip—could make all travel arrangements was not considered when I wrote the first edition.
