For the last week or so, I’ve been pondering a thought provoking article in the July 2008 issue of Wired - ‘The Petabyte Age,’ by Chris Anderson. I call it thought provoking because Anderson asserts that current statistical and theoretical methods will be trumped by the availability of HUGE amounts of data - PetaBytes (1000’s of terabytes), and the ability to process it. The basic idea is that with enough amounts of data, the numbers will eventually speak for themselves. I suppose the other reason this peaked my interest is that about a month ago I wrote about 'Crowdsourcing and the future of crisis reporting'. With enough data, you’d be able to ‘quite possibly’ predict future human and environmental disasters! While large amounts of data exist, the problem to date has been how to process it, and that’s how cloud computing comes into place.
Cloud computing is a relatively new word. Some people have used the term grid computing to refer to the same thing. It basically refers to the outsourcing and consolidation of computing services and resources. I’ll explain some more so that you can understand. The biggest nightmare to most companies IT departments has been dealing with scalability and the processing power or storage that is required to address it. Enter cloud computing companies - which would basically provide you with on-demand capacity as you grow. Some big companies you know have already been providing such services for the last few years; Amazon, Google, IBM and many more, each striving to be the next general-purpose computing platform. Basic services like Google Docs and Amazon S3 are modest examples of cloud computing.
Lately I’ve been following Google’s forays into Africa. Especially interesting has been the introduction of the Google Global Cache (You can read more about it on White African’s blog). Google in their infinite wisdom has come up with a way to deal with the voracity for data on the African continent. Because bandwidth demand surpasses supply, they would store the web on their servers and serve it up to users based on the shortest path to location, thereby improving performance. Some would call this cloud computing at its best. This would save on bandwidth costs for ISP’s, and improve performance for their customers. Wow!
If you don’t already know by now, that ‘Wow!’ in my last paragraph was meant to be sarcastic. While I applaud google’s efforts, google is inherently a corporation whose goal is ultimately profit. Google China is a prime example of how this all comes into play. Search results for ‘Tiananmen Square’, ‘Falun Gong’ or ‘Tibet’ yield far different results within China than outside it. The fallacies of cloud computing start to become clear. If a whole continent outsources its computing needs, isn’t this data then open to manipulation by the 3rd entity (Google) and other political and profit motivated interests?
Don’t get me wrong, I think Africa stands to benefit a great deal from ‘this’ faster access, but I think this means we need to step up our efforts to increase bandwidth instead of depending on a 3rd parties for access to information. We are at the dawn of the age of information, opening up new paradigms of thinking (some jokingly call it the age of mis-information). Just as happened during the industrial age, new products and integrated services are jostling for attention and marketplace attention. Ultimately there will be just a few winners.
Friends, readers - Africa’s sovereignty is at stake.
Celebrities like to portray it as a basket case, but they ignore very real progress.

Every enthusiast needs a skeptic around to keep them balanced. The power of positive thinking is immense—but so is its capacity for error, unless you take the time to answer the skeptics before committing yourself.
