Book on Infrastructure Architecture

14 July 10 - 11:55
Aandachtsgebied: default - Link naar dit artikel

A few months ago I started writing on a book on Infrastructure Architecture. From the introduction text of the book: 

With Infrastructure I mean all hardware, software and systems management needed to support IT applications. Infrastructure Architecture is the overall design of the complete IT infrastructure.

The book explains how infrastructure architecture works, the specific issues when designing and implementing IT infrastructures and how to address them. It provides practical solutions and examples for infrastructure architects and provides background information for IT managers, solution architects, system managers and others.

The book does not provide in-depth details on IT infrastructure components like servers, routers, switches and operating systems, nor does it explain details about protocols like TCP/IP, HTTP and other technical issues. Instead a more holistic view is chosen. All infrastructure components are described as one infrastructure ecosystem providing the fundament for applications running on it.

A short description of ITIL based systems management is provided, especially focused on managing the infrastructural parts of an IT system.

Infrastructures are complex by nature and provide many non- functional functions for building IT solutions on top of it. Non-functional attributes like performance, availability and security are key to a good infrastructure that provides the basis for running high performance, highly available and secure applications. Apart from these three most important attributes all other non-functional attributes of the ISO 9126 norm are described in this book, including tips on how to address them in an infrastructure design.

I found that there is no such nook available on the market today. Writing this book provides me with the opportunity to publish the knowledge and experience I have gained over the years. Apart from that much research is done to refresh my  knowledge and to get all details right. At this moment only 15% of the main text is finished, so I have a long way to go. I expect I need at least a year to finish the book, and probably more.

I am planning to publish parts of the books on this website, both to give you a sneak preview, and to invite you to reply to me on the published subjects and text. My email address is in the right hand column...

Guru4Pro - Cloud computing

Gisteravond heb ik deze presentatie gegeven over cloud computing. Er waren ongeveer 20 aanwezigen op de warme zomeravond in Amstelveen. De reacties van het publiek waren overwegend positief. Er ontstond meerdere malen een leuke discussie over de voor- en nadelen van de cloud.  

Mocht u het gemist hebben - geen nood: ik kom het verhaal op aanvraag graag bij uw organisatie ook eens vertellen! Mijn email adres staat in de rechterbalk.
