  • In fact, I've never met anyone who had tried the Oracle or DB2 clustering. Even the people who have the money seem to avoid it. Can anyone offer any personal anecdotes about it? Does it work at all?

    Sure it works. The reason you don't hear a lot of anecdotes is that most of the people who can afford it aren't out telling the public how they do it.

    Oracle "clustering" is probably used way more in internal, critical infrastructure, than in external, disposable content servers.

    One of Oracle's advantages

  • Two interesting things here are that none of them use PostgreSQL, despite a few of them being fairly new

    I agree here, PostgreSQL is not popular with scaling large websites. It's strengths are not well suited to that task. It is not nearly as fast as MySQL on reads, and is not as friendly as MySQL to setup for web developers. It is the hidden P in LAMP (although my version of LAMP is Linux Apache Mod_perl Postgresql).

    PostgreSQL is best suited for applications which require higher than 10 to 1 ratio

  • I did find it very interesting to have technical reports of how these popular companies try to scale. The flat files are slightly more scary than MySQL, which is a known commodity at least. I am surprised that replication and backups are still so hard to pull off - it should be all plug and play already. I thought this was the future!
