One of the toughest jobs for managers today is keeping up with the rapid change in technology. The advent of Web Services and service-oriented architectures makes this all the more important, because these technologies are going to fundamentally change the way we build our internal systems – the information systems that support our organizations – and how our internal systems interact with external systems. There has been nothing like this before in the software industry. We are on the cusp of building “plug-compatible” software components that will reduce the costs of our software systems at the same time increasing the capabilities of the systems. Sure, you have heard that promise more than once before. And more than once, the delivery fell short of the promise. But, as with such promises, they will come true some day. That time is now.
This is a guide for the savvy manager who wants to capitalize on the wave of change that will occur with Web Services and service-oriented architectures. The changes wrought by this technology will require both a grasp of the technology and a way to deal with how these changes will affect the people who build our systems in our organizations. This book covers both issues. Managers at all levels of all organizations must be aware of the changes that are on the horizon and ways to deal with both sets of issues.
This is a non-technical book on a technical subject. It assumes no prior knowledge of the technology. It is written with a high-level view at the beginning of the book. As the book progresses, technical details are introduced and explained. You can keep reading until you have enough understanding of the technology for your use. If you read through to Part III, you will see some architectural options that you might consider when using Web Services and service-oriented architectures. Part IV serves as a reference guide for the buzzwords and acronyms associated with this technology.
This book does not define a new methodology. Instead, it shows how aspects of a service-oriented architecture augment or are compatible with most software architecture methodologies and frameworks.
The intent of this book is to give you both an opportunity to consider some ideas and advice that just might make it easier for your organization to realize the potential benefits in Web Services and service-oriented architectures.
