On architectures (Enterprise, business, IT, SOA, and solutions)
The first time that an IT professional showed me a plan of IT architecture, he shared a map of a plant on an A0 format (1 square meter). This map showed buildings with their IT infrastructure. This included the location of the servers, which software was running on which server, and even the cable layout. This map of IT architecture helped the poor man find his way around the servers that he had to administer. The plant in question was very big. His physical condition also deserved a lot of respect, because of this huge map roll that he had to carry everywhere he went, to save himself from getting lost. Compared to the Michelin guide you would use in a car, this man’s IT architecture map was hell (European city planning still seems to be popular as a framework for IT architecture).
