[one-users] CY12-Q3 Community Analysis — OpenStack vs OpenNebula vs Eucalyptus vs CloudStack

[Qingye Jiang (John)]

Hi Christopher,

First of all I apologize for not starting a new thread for this topic. 
It was my fault and I will avoid that in the future.

In the process of selecting an open source project for production 
deploy, I think there are four aspects to consider:

A. architecture
B. installation, functionality and code maturity
C. community activity
D. commercial support

There have been a lot of literature related to A & B, and information on 
D is relatively easy to obtain if a customer really wants it. However, 
there exists very few literature related to C, therefore my quarterly 
report is only a far-from-mature attempt to fill in the blank. This 
effort was started in CY11-Q4 out of personal interest, but a lot of 
people are interested in the results so I decided to publish it, and 
continue the work once a quarter. Actually each time I prepare a new 
version of the report, I found new things to consider. Some of your 
comments are already in my TODO list, and might be part of my CY12-Q4 
report.

Frankly speaking, I myself actually use OpenNebula a lot, and am 
familiar with each and every piece of its Java API's. Although 
OpenNebula is relative low in terms of community activity, that does not 
mean OpenNebula is not good.

Again, thank you so much for the comments.

Best regards,

John
