Benchcfe Factor

As part of my analysis on the state of cloud providers in the market, this time I carried out a broader measurement to obtain the factor that I have called "Benchcfe" which basically translates into a metric to determine the cost per efficiency of a unit of compute (VM, instance, or even bare metal).

Due to some comments on my previous article , I sought to expand the study, testing various versions of instances offered by providers.

To achieve this, the first thing I did is create a bash script that allows obtaining the necessary values and that must be taken to a table for the respective calculations, you can find it in this repository .

The results are very interesting in general and in particular the abysmal difference in performance offered by the large ones (Azure, Aws, GCloud) in relation to the smaller ones (Digital Ocean, Vultr, Hetzner), the latter are up to 100 times more efficient in many aspects.

On the other hand I found a serious problem in AWS: when generating a large file, say 16 GB, the disk read/write performance drops drastically to scary IOPS, that problem may be due to infrastructure failure, overselling or some failure in the data bus, my tests were sent only to one data center but soon I will do more validations and check if it is widespread or only in Virginia(US).

I added something extra to the analysis: a speed benchmark between data centers and instances, especially useful now that we want to scale our data centers, integrate them with a multi-site approach. I was pleasantly surprised with the performance that Azure offers in general to connect with various providers, in many cases exceeding 1 GB/s, which does allow the integration of two or more networks.

Finally, I invite you to read the article in the repository and review the sources that contain the data, particular metrics and graphs.
