This slide deck dives a bit in history to understand where IT comes from, where we are now and why we are there and what our options are. It starts with exploring the paradigms of the markets companies live in, travels through matching organizational approaches and finally looks at the history and current state of IT.
Based on that and after a quick look at Conway's law the market paradigms and organizational approaches are evaluated with respect to the drivers they imply on IT in general and architecture particularly.
And after all that foreplay (which is necessary to really understand where we are and what the forces are) several architectural styles and technologies are located on the scale that the market paradigms and organizational approaches span. This way sort of an "architectural fitness detector" is provided which helps to make architectural choices based on needs instead of hypes or habits (which are way to often the choice drivers).
The slide deck then finishes up with a few mismatches that are seen quite often in reality and it can be seen how the distance between architectural choices on the presented scale can be used to quickly determine potential mismatches.
As always the voice track is missing but I hope that the slides are still of some help for you.
