"I think there is a world market for maybe five computers"
but it might have been Thomas Watson in 1943, president of IBM, but it might be a myth.
The thinking was that a number of large mainframey computers would be built and used by the world. That of course, didn't happen, as my watch has more memory than ENIAC did, and there's computers everywhere, but as the web continues to mature, I believe that things will conflate in the next 10-15 years and as more and more companies begin to
All this is building a collective trust with large entities like Amazon, and as prices fall with uptimes rising, more companies will say, "who am I to build a datacenter? I'll just host in one of The Five."
Here's a list of services (by no means exhaustive) from Wikipedia's Utility Computing article, as of today:
I believe this list will likely turn into The Five Computers:
This "5th computer" will be the "remainder" after the first four, but might ultimately become the largest. Perhaps it's a larger number, but surely Amazon will buy Bay at some point, and Google will buy Salesforce.com, so they don't count.
Computing will be moved into the Cloud. It's already happening, we're 20% there. The idea has been around since the beginning, and it will, in my opinion, continue come up until it actually happens and we build Skynet. One of these compute clouds will no doubt end up in orbit.
