Overview

Service Virtualization:Reality Is Overratedis a practicalintroduction tothe capabilities, benefits, and modalities of service virtualization for achieving dramatic improvements in the efficiency, reliability, predictability, speed, and cost of delivering enterprise application software. Service virtualizationis a powerful emergent method for emulating ("faking") the behavior of specific components in composite applications such asservice-oriented architectures in order to remove dependency constraints on the development and testing of enterprise software.

Service virtualization—commoditizedsince 2007 by such companies as ITKO (Lisa), Parasoft (Virtualize), Hewlett-Packard (Service Virtualization), and IBM (Green Hat)—providesenterprise software teams access to “virtual assets” that are deployed locally or in the cloud to obviate the need to access the entire service system or any of its live components subject to dependency constraints, such as third-party control, inaccessibility, or inconvenient, inadequate, incomplete, or prohibitively expensive availability. Authors John Michelsen and Jason English—respectively the CTO and marketing director of ITKO/CA Technologies—are pioneers, architects,and industry advocates of service virtualization. Their richly illustrated guide is intended for the executives of all businesses that use software, as well as for IT practitioners on software engineering, testing, and environments teams.

What you’ll learnYou 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 in 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.
