Bondi - Foundations of software and system performance engineering: process, performance modeling, requirements, testing, scalability, and practice

ePUB is an open, industry-standard format for eBooks. However, support of ePUB and its many features varies across reading devices and applications. Use your device or app settings to customize the presentation to your liking. Settings that you can customize often include font, font size, single or double column, landscape or portrait mode, and figures that you can click or tap to enlarge. For additional information about the settings and features on your reading device or app, visit the device manufacturers Web site.

Many titles include programming code or configuration examples. To optimize the presentation of these elements, view the eBook in single-column, landscape mode and adjust the font size to the smallest setting. In addition to presenting code and configurations in the reflowable text format, we have included images of the code that mimic the presentation found in the print book; therefore, where the reflowable format may compromise the presentation of the code listing, you will see a Click here to view code image link.

If this book had only been available to the contractors building healthcare.gov, and they read and followed the lifecycle performance processes, there would not have been the enormous problems apparent in that health care application. In my 40-plus years of experience in building leading-edge software and hardware products, poor performance is the single most frequent cause of the failure or cancellation of a new, software-intensive project. Performance requirements are often neglected or poorly formulated during the planning and requirements phases of a project. Consequently, the software architecture and the resulting delivered system are unable to meet performance needs. This book provides the reader with the techniques and skills necessary to implement performance engineering at the beginning of a project and manage those requirements throughout the lifecycle of the product. I cannot recommend this book highly enough.

Well written and packed with useful examples, Foundations of Software and System Performance Engineering provides a thorough presentation of this crucial topic. Drawing upon decades of professional experience, Dr. Bondi shows how the principles of performance engineering can be applied in many different fields and disciplines.

who taught me how to analyze and debug.

The performance engineering of computer systems and the systems they control concerns the methods, practices, and disciplines that may be used to ensure that the systems provide the performance that is expected of them. Performance engineering is a process that touches every aspect of the software lifecycle, from conception and requirements planning to testing and delivery. Failure to address performance concerns at the beginning of the software lifecycle significantly increases the risk that a software project will fail. Indeed, performance is the single largest risk to the success of any software project. Readers in the United States will recall that poor performance was the first sign that healthcare.gov, the federal web site for obtaining health insurance policies that went online in late 2013, was having a very poor start. News reports indicate that the processes and steps recommended in this book were not followed during its development and rollout. Performance requirements were inadequately specified, and there was almost no performance testing prior to the rollout because time was not available for it. This should be a warning that adequate planning and timely scheduling are preconditions for the successful incorporation of performance engineering into the software development lifecycle. Building and then tuning is an almost certain recipe for performance failure.
