CenturyLink expands list of cloud centers
CenturyLink recently added two data centers to its existing list of nine dispensing cloud services. They are in Santa  Clara, Calif., and Sterling, Va. By mid-year, it plans to have cloud data centers in the London area and Paris. When CenturyLink acquired Savvis, it boosted its total number of data centers around the world to 55; 13 will be cloud service centers by mid-2014.

How CenturyLink defines a virtual CPU
A virtual CPU in the CenturyLink lexicon is larger than how several suppliers define one. It is the equivalent of a 2 GHz Xeon processor, such as an Intel Sandy Bridge or Ivy Bridge E5-2670s, Ivy Bridge now weighs in above 2 GHz, more like 2.5 GHz. Each cloud supplier defines a virtual CPU differently, making comparisons difficult.

Re: How CenturyLink defines a virtual CPU
I realize that this is a specialized application specifically aimed at high I/O rates, but I wonder if it heralds the beginning of the end for HDDs in servers in favor of SDDs?

Re: How CenturyLink defines a virtual CPU
Gary, I think you are right, SSDs have already become the boot partition in many consumer devices and in the datacenter their benefits are becomes too large to ignore. It's just a matter of time now, when we start viewing the HHDs as floppy disks.

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.
