The book, published by Auerbach Publications
Inc, can be summarised as follows:
The emphasis in this book
is on pre-empting performance and scalability problems in production systems by
tackling the issues during the early stages of the system lifecycle. It shows
how to reduce technical risk, thereby helping to ensure that service level
requirements can be met, and thus saving costly rework, redevelopment, and
purchases of additional equipment. It includes discussions on the
non-functional aspects of IT procurements from the perspective of both the
client and the bidders. The watchword throughout is on an approach that is both
cost-effective and "fit for purpose", necessary requirements in the
modern age when there is increasing pressure to deliver in ever shorter
timescales.
Performance Assurance for IT Systems is a comprehensive, readable guide to the
approaches and techniques for addressing IT performance and related technology
issues throughout the system lifecycle. Written by an industry expert with many
years of experience in addressing performance and technology issues on a wide
variety of systems, the text is loaded with practical advice, easily applied
techniques, and useful reference material. It is valuable for a range of IT
professionals, including Performance Analysts, Technical Architects, Designers,
and IT Managers who are involved in the assessment of technical risk.
