Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
Since few systems exist in complete isolation (and ours is no exception), architecture decisions often make far less sense without a bigger picture of how those pieces fit into the whole. That’s the goal here, to cover the big picture. Many subsequent posts will do deep dives into specific areas. This will be a logistical overview with hardware highlights only; the next post will have the hardware details.
