Many of you will remember the fanfare and bravado surrounding Sun Microsystems’ Sep. 2004 announcement of a $1 per hour per processor utility computing plan. What you won’t remember is Sun revealing a single customer using the service. That’s because it hasn’t. More than one year since it first started hyping the “pay-for-use grid computing services” Sun is still weeks away from presenting a customer to the public. The program has proved much tougher to sell that Sun ever imagined.
