So Google now has its own IaaS solution called Google Compute Engine.
谷歌现在有了自己的IaaS解决方案谷歌计算引擎。
As a heavy user of cloud computing, I'm trying to figure out the difference between Amazon's EC2 Compute Unit and GCEU (Google's Compute Engine Unit) - to ascertain price-for-performance differences, etc.
作为云计算的忠实用户,我正试图找出Amazon的EC2计算单元和GCEU(谷歌的计算引擎单元)之间的区别——以确定性价比差异,等等。
Does anyone have more insight into the differences between these two?
有没有人对这两者之间的差异有更深入的了解?
ANSWER: Looks like 1 GCEU ~= 1 EC2 compute unit. More below at accepted answer.
答案:看起来是1个GCEU ~= 1个EC2计算单元。以下是大家公认的答案。

According to Amazon,
根据亚马逊,
One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor. This is also the equivalent to an early-2006 1.7 GHz Xeon processor referenced in our original documentation.
一个EC2计算单元提供的CPU容量相当于1.0-1.2 GHz 2007 Opteron或2007 Xeon处理器。这也相当于我们原始文档中引用的2006年初的1.7 GHz Xeon处理器。
According to Google,
根据谷歌,
GCEU (Google Compute Engine Unit), or GQ for short, is a unit of CPU capacity that we use to describe the compute power of our instance types. We chose 2.75 GQ’s to represent the minimum power of one logical core (a hardware hyper-thread) on our Sandy Bridge platform.
GCEU(谷歌计算引擎单元),简称GQ,是我们用来描述实例类型的计算能力的CPU容量单元。我们选择了2.75 GQ来表示Sandy Bridge平台上一个逻辑核心(一个硬件超线程)的最小功耗。
It's hard to make a 1:1 comparison with such a vague description from Google. Assuming Amazon and Google use the same CPUs, this would be as follows:
很难与谷歌中如此模糊的描述进行1:1的比较。假设Amazon和谷歌使用相同的cpu,这将如下所示:
Using Amazon's Cluster Compute Eight Extra Large Instance as an example, because it defines the CPU and the CU rating.
使用Amazon的集群计算8个额外的大型实例,因为它定义了CPU和CU的级别。
88 EC2 Compute Units (2 x Intel Xeon E5-2670, eight-core "Sandy Bridge" architecture)
88个EC2计算单元(2 x Intel Xeon E5-2670, 8核“Sandy Bridge”架构)
This is 32 logical cores, 2x 8 physical with hyperthreading. With Google's rating of one logical core being 2.75 GQ, this turns out to be in-line with Amazon, being 88 GQ in total.
这是32个逻辑内核,2x 8是带超线程的物理内核。谷歌对一个逻辑核心的评分是2.75 GQ,这与亚马逊的评分是一致的,总共88 GQ。
Again, this is assuming Google and Amazon would use the same CPU (which is likely), and would be impossible to know without an official statement from Google, or a CPU-stat from a running instance.
同样,假设谷歌和Amazon会使用相同的CPU(很可能),如果没有谷歌的官方声明,或者运行实例中的CPU-stat,就不可能知道。
