Don -

I think you touched on this... But, just the CURRENT crawling aspect of the operation requires far more cycles/processor/hour than providing the search results back to the browser EVER will. (Well, EVER is a strong word here and subject to change :)

If the hosted apps are adopted at anywhere near the expected rates they still won't touch the horsepower required to keep up with the sprawl of the net over time as it is growing at a far faster rate than apps adoption.

Hello Don,

Gulker says Google has 450,000 servers, and there are 900 million computer users in the world, which means Google "supports" 2000 users per server. Then he says that 2000 users is no big deal for a server.

You go on to say Napster supported 8000 users per server.

Obviously all 900 million users will not be using Google services, and definitely not all at the same time. Does the 2000 users per server imply simultaneous use? Or is using the total number of computer users divided by number of servers some standard web server calculus? If not, as I assume, the 900 million metric is not very useful, as it does not indicate how many users are, on average, using Google servers. And, if 2000 simultaneous users per server is no big deal, Google probably has a while to go before they get there, right?

Just curious.

Considering Verizon's FIOS (45mbps in the home) and AT&T (25mbps) spending over $4 billion on it's Project Lightspeed, bandwidth availability to consumers will increase exponentially. With that in mind, I hope those data centers come online quick! I switched to search.msn.com recently and the I love it, the only major drawback I find is that it's a bit slower than google.com when I search the tail end.

Wow, as soon as I posted my last comment, I came across this link: http://search.msn.com/s/jobs/openings/search%20jobs.htm

Apparently search.msn.com hand craft results in real-time on the tail end. I guess that's why my queries have been slow when I search on the tail end.

From the "Hand crafted results" job posting, it seems like they have a team of over 100 handcrafters responding to queries in less than 3.8 seconds... that's eye-opening.

It'll be interesting to see which architecture scales better. This is basically the biggest test there is of the two company's technology. Microsoft will probably have the most riding on this since if they don't scale well it'll reflect badly on their server software sales.


With SaaS taking off and multitude of companies wanting to provide all sorts of web services, should we all be buying stocks in data centers?
