Internet Architecture Video

Back sometime in 2004/2005 when I was the CIO/SVP of Engineering for CNET Networks, they shot a video of me explaining, “Scaling out an Internet Architecture“.  I was thinking about the current publishing system at AOL, DynaPub, that we developed in 2007 after I arrived.  It was interesting after I watched the video again how close DynaPub follows the key principles described in it.

The only parts the video does not cover are:

  • Use of Lucene as the Search engine and SOLR as the container to hold Lucene (we invented SOLR while I was at CNET).
  • Use of XML over HTTP as the transport layer between the App Servers and DBs / Search engine.
  • Use of denormalized MySQL tables for speed
  • The main tool, the CMS, and its very specialized table structure for high-performance.

The AOL Publishing system is the fourth generation publishing system that I have been involved in either designing or managing.  IMHO, most of the: bloated, over-designed, needlessly complex issues from previous publishing systems have been eradicated in DynaPub.  It also has ZERO licensing or maintenance costs as it is all built on open-source – including the operating system – as mentioned in a previous blog post here.
