NEW YORK ( TheStreet) -- In the history of computing, an innovation has defined each decade and its technology leadership.
Some of the biggest price-to-earnings ratios in the land are to be found at cloud technology outfits VMWare ( VMW), Rackspace ( RAX) and Red Hat ( RHT). The idea is that the software that people choose to run their clouds -- the "cloud stack" -- will grow these companies, as every enterprise works to replace client-server computing with more cost-efficient clouds. Maybe. But a key to cloud development is the favoring of open-source software, where the software's benefits benefits flow mainly to users, not vendors. VMWare could be the cloud's Apple or its Microsoft, because its vSphere infrastructure is largely proprietary. Or, if the money is to be found in cloud-hosting and open-source, Rackspace could win the prize. If open-source itself is the key, maybe Red Hat will triumph. As you can probably tell, I'm skeptical about those possibilities. Not that the companies are bad investments. They just may not define cloud when the history of our time is written. Another way of looking at this is in terms of services. Software as a Service is the result of using clouds, delivering enormous bang for the customer's buck. That's what Salesforce.com ( CRM)is claiming. That's really what Amazon.com ( AMZN) is about, with the retailing giant used to generate demands for digital files and cloud infrastructure. I own a little Amazon, but when you put its earnings next to its price, it's nearly fully valued. The excitement about Facebook is really about cloud. Facebook is, at its heart, a cloud application. It could not have scaled as quickly as it did without cloud architecture. It's a wonderful demonstration of the power cloud technology has. But I think it's more likely that the people hyping Facebook to you right now are selling stock. The "social computing" boom feels to me like the dot-com bubble, and in many ways it has popped, with the shares of many social computing outfits trading at less than their offering prices. My view is: Let the private investors take that hit. Wait until there is some "there" there with Facebook. Let's see some operating numbers.
