The New Economics of Computing.
Professor Nicholas Carr is a Professor in the business faculty at Harvard. He is probably most famous for his controversial article "IT Doesn't Matter" and the follow on "Does IT Matter, an HBR Debate". June 2003. Since these publications he has written a few books on the topic of IT and writes a blog about the way he sees technology and technology trends influencing business.
He has been talking about the implications of "Cloud Computing" and what the paradigm change means to business, both technical and other businesses. In his recent post he makes some comments about the significance, and an example of how cloud computing does provide real value. (Recall the People, Ideas & Objects application will be accessed through the "Cloud Computing" method.)
My favorite example, which is about a year old now, is both simple and revealing. In late 2007, the New York Times faced a challenge. It wanted to make available over the web its entire archive of articles, 11 million in all, dating back to 1851. It had already scanned all the articles, producing a huge, four-terabyte pile of images in TIFF format. But because TIFFs are poorly suited to online distribution, and because a single article often comprised many TIFFs, the Times needed to translate that four-terabyte pile of TIFFs into more web-friendly PDF files. That's not a particularly complicated computing chore, but it's a large computing chore, requiring a whole lot of computer processing time.My experience with "Cloud Computing" has involved renting processors on Sun Microsystems network.com and Amazon's Web Service offerings. You should set up an account on one of these services to understand the full scope of the power that is offered to the user. If you have a processing problem that can take 100 hours of processing on your computer, hoisting it up on one of these services will not only allow you to process the problem far more cost effectively as Professor Carr points out. But you would also recieve the results for this 100 hour job within a matter of minutes. To me this was the intoxicating aspect of cloud computing.
Fortunately, a software programmer at the Times, Derek Gottfrid, had been playing around with Amazon Web Services for a number of months, and he realized that Amazon's new computing utility, Elastic Compute Cloud (EC2), might offer a solution. Working alone, he uploaded the four terabytes of TIFF data into Amazon's Simple Storage System (S3) utility, and he hacked together some code for EC2 that would, as he later described in a blog post, "pull all the parts that make up an article out of S3, generate a PDF from them and store the PDF back in S3." He then rented 100 virtual computers through EC2 and ran the data through them. In less than 24 hours, he had his 11,000 PDFs, all stored neatly in S3 and ready to be served up to visitors to the Times site.
The total cost for the computing job? Gottfrid told me that the entire EC2 bill came to $240. (That's 10 cents per computer-hour times 100 computers times 24 hours; there were no bandwidth charges since all the data transfers took place within Amazon's system - from S3 to EC2 and back.)
Go ahead and try one of these web services. If you need help figuring out what type of problem to solve, use this Princeton University book. (Download the first chapter, its free.)
