I understand what Lorell means - the web 2.0 scaling model is to throw resources, rather than intelligence at your bottlenecks.
I think this is a little hard. Just about all the Web 2.0 presentations I see have a big bit that says that how they had to redesign and rearchitect each time their customer level increased by a factor or 10 or so. The newer companies are learning from this and implementing scaling from the start. Most of these companies are less than a dozen people and sometimes go from nothing to "Top 1000" site in months or a year or two. The aim these days is to make sure you can do that. Take a look at Pages 8-11 of this ( ppt -> flash presentation): http://s3.amazonaws.com/slideshare/ssplayer.swf?id=122183&doc=aiderss-aws-the-startup-project708 These people don't care about power, space, aircon and bandwidth problems. They just buy off others companies (eg Amazon) who specialise in those problems and charge the Web 2.0 companies what it costs them to solve. As for where the Blackboxes will be used, It'll be where companies want servers in place in weeks or months and existing datacenters are full or in the wrong place. Think of a building full of people processing insurance claims in India or a cluster delivering video on demand in each Asian city with more than 500,000 people. -- Simon Lyall | Very Busy | Web: http://www.darkmere.gen.nz/ "To stay awake all night adds a day to your life" - Stilgar | eMT.
