Read Turn Off the Cloud Lights! by Jim Groom (
One of the things I have been doing over the last couple of months is tracking how many resources (known in Reclaim Cloud as cloudlets) each application environment requires. This is important because the more cloudlets you use the more you pay, so trying to be as efficient as possible is quite important. A cloudlet = 128 MiB + 400 MHz. Or, the equivalent of a ridiculously fast personal computer circa 1996 or 1997.
