Re: How CenturyLink defines a virtual CPU
Great article and wonderfully explained. Comparing CPUs to gain the best possible price/performance ratio has been a problem for the buyer since quite some time. AMD tried solving this by labeling a CPU with a number, so for instance an Athlon 2800+ @1.8GHz was supposed to be as good an Intel P4 @ 2.8GHz. It worked for some time but with the explosion of HT, multi core and new architectures etc and applications rely on different things, this numbering scheme also took a backseat. I believe the desktop and mobile world have a good solution at present in terms of using benchmarking tools to determine the best price/performance ratio.
Add memory into the equation and it's like you said, things become even more complicated. However, based on the application type, I think it would be fair to say that CenturyLink at $0.22 per hour is a better chose provided the application requires low I/O, and 10x performance gains are manifested and utilized.
