I was able to read part of the ebook version on OReilly and specifically the Discussion on Architecture Decomposition.
It feels to me like the discussion of tiers, layers and service level requirements is heavily based on "The Sun 3-D Architectural Framework", more specifically the SunTone "Cube".
Could you tell me if the SunTone Architecture Methodology is still used in some form or other by Sun itself. Are there any plans to (re-)introduce this ? Maybe at Oracle ?
