IT Infrastructure Architecture: Infrastructure building blocks and concepts ReviewWith "IT Infrastructure Architecture - Infrastructure building blocks and concepts", Sjaak Laan provides a broad and coherent picture of IT-infrastructure. The book presents an -introduction- to this subject; (technical) details only occasionally come into play. According to Laan a book covering the full width of the domain does not exist yet. He also states that his book is well suited to explain the interests as well as the complexity of the field of IT-infrastructure.
The author introduces his "Infrastructure Model" in chapter 1. This model is used to structure the remainder of the book. The book can be divided into two parts: a quality part and an concrete part. The quality part (chapter 2 - 5) discusses the concepts Availability, Performance and Security with respect to IT-infrastructure as a whole. The concrete part (starting with chapter 6) discusses the building blocks Data Centers, Servers, Networking, Storage, Virtualisation, Operating Systems and End User Devices.
For each of the concepts discussed in chapter 3, 4 and 5 Laan provides a number of aspects and patterns. Per building block (as of chapter 6) the author systematically focuses on historical developments, constituent parts and details of the applicable quality notions (Availability, Performance and Security).
Laan doesn't justify the correctness, completeness etc. of his Infrastructure Model. The same goes more than once for the constituent parts of the building blocks he discusses. And that is a pity, for that would further increase the power of his book.
The book is pleasantly ordered and reads easy. It contains a whole load of orienting information and can sure be used, in my opinion, as a reference work. The accessibility of the book leaves room for improvement: chapters/paragraphs are not numbered and organising/structuring text fragments are missing several times.
Summarising: Laan's first book, "IT Infrastructure Architecture", is an asset and a must for everyone who wants to (re)orient on the subject without being swamped by numerous details and technicalities.

Too Big to Fall: America's Failing Infrastructure and the Way Forward ReviewToo Big to Fall is too important not to be read by elected and government officials and anyone who cares about the health of our cities, states, and country. LePatner, by concentrating on a major element of public works--our country's 600,000 bridges, brings into focus the causes and solutions that, if followed, in the long run would actually cost less and expose us to less risk. The release of this book could not be more timely. Thousands of local and state officials are facing record deficits. The easiest areas to cut are the nearly invisible activities of preventive maintenance. No large constituencies will be marching on city halls or statehouses to clamor to save the jobs of bridge painters or oilers. But now at least government public works managers and citizens have the source to educate elected officials and their bean counters in the penny-wise-pound-foolish choice of cutting maintenance now, only to face bigger costs and higher risks in just a few years. I was in charge of New York City's bridges after the fiscal crisis of the 1970s. On my watch in the 1980s, we had fatal collapses on the Brooklyn Bridge and the elevated FDR drive, as well as emergency closures of more than a score of other bridges. LePatner offers us a better choice.
