"You can handle a much larger number of connections provided they don't do anything useful."
Define useful? I think you mean, computationally complex, but that isn't the same thing as useful. At my last job I worked on a web crawler, and fetching a page, then persisting it in our grid, was useful work. It was useful to have more than 10k connections in that context.
One of my pet peeves is this idea of throwing servers at problems. We currently have enormous problems with power and heat dissipation in data centers. At my last job, where I did the web crawler, we couldn't put any more servers in our data center because we didn't have enough power. Doing more, with fewer servers can be very important.
I also wonder how much larger the carbon footprint of computing is because of such philosophies.
