Annual Computer Server Sales

At a recent presentation, Scott McNealy, the Chairman of the Board at Sun Microsystems, stated that estimates for 2007 were that worldwide sales of server computers were 8 million units. They believe that 1.5 million of these servers were purchased by Google. If you estimate the numbers purchased by Yahoo, MSN, Amazon.com, and Salesforce.com, it paints a picture in which server side computing is being dominated by a few big service providers. This seems to align with a statement that Sun’s CTO made in 2006 that “the world only needs 5 computers”. Most of these companies are creating a server-side infrastructure that can handle a huge load of the world’s computing needs as a subscription service, with few applications residing on the client-side (a.k.a. desktop or thin-client machines).
