Story of the book.

The origin of Fundamentals of IT architecture is based on the codename Akropolis project that started in Stockholm 2013. The goal of the Akropolis project was to create an atlas of IT architecture that reflected the essential topics at the time. The project was run by a team of six editors with the support of approx. 40 authors, reviewers, and domain experts. The result became the initial Book of IT architecture from Hoi Publishing, which was released with the partners Centiro, IASA, Microsoft, and the Swedish Computer Association. In 2019, a big investment in a two year rewrite project was initiated by the Knowledge House , the lead editors and an editorial team in UK with the goal to create an updated atlas reflecting changes in technology and modern business. The resulting new Fundamentals of IT architecture was released worldwide in May 2021.
