    • Book Description

      • Software drives innovation and success in todays business world. Yet critical software projects consistently come in late, defective, and way over budget. So whats the problem?

        Get ready for a shock, because the answer to the problem is to avoid reality altogether. A new IT practice and technology called Service Virtualization (SV) is industrializing the process of simulating everything in our software development and test environments. Yes, fake systems are even better than the real thing for most of the design and development lifecycle, and SV is already making a huge impact at some of the worlds biggest companies.

        Service Virtualization:ÿReality Is Overratedÿis the first book to present this powerful new method for simulating the behavior, data, and responsiveness of specific components in complex applications. By faking out dependency constraints, SV delivers dramatic improvements in speed, cost, performance, and agility to the development of enterprise application software.

        Writing for executive and technical readers alike, SV inventor John Michelsen and Jason English capture lessons learned from the first five years of applying this game-changing practice in real customer environments. Other industriesfrom aviation to medicinealready understand the power of simulation to solve real-world constraints and deliver new products to market better, faster, and cheaper. Now its time to apply the same thinking to our software.

        What youll learn

        You will learn why, when, where, and how to deploy service virtualization (SV) solutions to mitigate or eliminate the constraints of an unavailable or unready service system by simulating its dependent components ÿin order to deliver better enterprise software faster and at lower cost. In particular, you will learn step-by-step why, when, where, and how to deploy the following SV solutions:

        • shift-left
        • infrastructure availability
        • performance readiness
        • test scenario management

        Who this book is for

        This book is not only for IT practitioners on engineering, testing, and environments teams engaged in the development and delivery of enterprise software, but also for executives of companies in all sectors who need to understand and implement emergent opportunities to improve the time to market and overall competitiveness of any outward-facing business strategy that has a software application component.
