    Further, the design of Amazon’s database is remarkably like the internal data structures of modern programming languages. Very much like a hash or a dictionary (what Perl and Python call these structures) or Frontier’s tables, but unlike them, you can have multiple values with the same name. In this way it’s like XML. I imagine all languages have had to accomodate this feature of XML (we did in Frontier), so they should all map pretty well on Amazon’s structure. This was gutsy, and I think smart.

    A Manila server would work fine for a few thousand sites, but after that it would bog down because the architecture couldn’t escape the confines of a single machine it was designed for in the 80s. (Before you say it’s obsolete, there still are a lot of apps for single machines. Perl, Python, JavaScript and Java share the same design philosophy.) Permalink to this paragraph
