ANOVA Explanation

#1
Hey Guys, am not a statistician but came across a publication when researching on cloud computing but have not been able to understand the calculations even after laying my hands on all the references. Please i just need the steps for me to understand how tables 2,3,5 and 8 were obtained. I have also tried contacting the author of the report but its been over 6 months and he has not even replied. I would really appreciate if it is sent to my e-mail:eek:k_stanlo@yahoo.com. The url for the report is: http://www1.cse.wustl.edu/~jain/cse567-11/ftp/clouds.pdf. I also uploaded it here but don't know if it was successful.

Thanks in advance for your help.
