Here's something you won't see mentioned, though: the main attraction of the cloud to investors and entrepreneurs is the idea of making money from you, on a recurring, perpetual basis, for something you currently get for a flat rate or for free without having to give up the money or privacy that cloud companies hope to leverage into fortunes...Not every cloud has a silver lining
Now, this makes sense for some limited applications. If you're supplying a service to the public, having a cloud's worth of on-demand storage and hosting is great news. Many companies, such as Twitter, have found that it's more cost-effective to buy barrel-loads of storage, bandwidth and computation from distant hosting companies than it would be to buy their own servers and racks at a data-centre. And if you're doing supercomputing applications, then tapping into the high-performance computing grid run by the world's physics centres is a good trick.
But for the average punter, cloud computing is - to say the least - oversold. Network access remains slower, more expensive, and less reliable than hard drives and CPUs. Your access to the net grows more and more fraught each day, as entertainment companies, spyware creeps, botnet crooks, snooping coppers and shameless bosses arrogate to themselves the right to spy on, tamper with or terminate your access to the net.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
