I had the good fortune of meeting André Bondi this year at ICPE '15 (which is where I learned about Foundations) and he was a fascinating, enthusiastic, and wonderful person to talk to. After I had presented my paper on Defining Standards for Web Page Performance, he approached me and we had a wonderful discussion about performance requirements and the perspective of the end-user and he had great things to say about the work that I was doing. His energy and interest in the subject was plainly obvious. It was a pure pleasure to have the opportunity to meet and talk with him.
As for Foundations, I haven't read very far into it yet, about 60 pages or so, but I have gone through and skimmed each section. This book is shaping up to be a fantastic resource and introductory guide to Performance Engineering. Since it is based on a training course that Dr. Bondi developed to train performance engineering and testing teams, I would expect no less. The book covers the entire software lifecycle from the perspective of how it connects with Performance Engineering as a practice, from requirements, to metrics, analysis, workloads, testing, instrumentation, and validation, and how they work within Agile environments and how to communicate and work with stakeholders on the project.
I won't write a complete review of Foundations yet as I still have much more to read, but I can be quite sure that this book is going to take a prominent place on my bookshelf, and play an important role while I am training my own performance engineering team.
