"Not that Red Hat or any other software company has much of a chance of making money from Amazon's EC2 compute cloud and related S3 and EBS storage clouds, of course.

But if you want to do cloud computing - and let's face it, some portion of computing will be done on private and public clouds - you have to engage with Amazon and other emerging cloud providers like IBM with its IBM Cloud and Sun Microsystems Oracle with its Sun Cloud. Even if this does sound like a lot of marketing fluff on what can honestly be called computing."
