Scenarios
Scenario 1
There is a Wordpress based blog.
The client is worried: How many visitors can they handle before they die.
Establish a baseline: How many page displays per second AT LEAST we can handle. Disruption of the site operation is NOT acceptable.
Minimal budget!
Be as detailed and technical as You possibly can.
Post to the discussion group the following information:
- Detailed description of the simulation of the site. eg. if You're going to virtualize it then how? If You are running it as a process, then how You separate it from the real machine?
- Detailed description of the attack / benchmark tools picked. Where You are going to run them? What tools? How many copies? How you are going to collect the results?!!!

Lab 1
We will need to create two different virtual machines, one is going to be the wordpress server and the 2nd one is the client which is used to attack the server. It's probably easiest to install only one image and then clone it.
Hard disk image cloning is best done with
Linux:
VBoxManage clonehd FirstUbuntu.vdi SecondUbuntu.vdi
Windows:
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonehd FirstUbuntu.vdi SecondUbuntu.vdi
After cloning the image create another virtual machine and attach the 2nd disk to that machine. As the result there will be two different virtual machines with two different virtual hard disks.
To be able to connect between the two virtual machines, You need to add an additional network adapter to both hosts. It can be either "Host Only" or "Internal" type.
To enable the new adapters in Ubuntu edit the file: /etc/network/interfaces
Scenario 2
Design a method for evaluating any speedup solutions for the wordpress. A repeatable process to evaluate the claims. Whatever optimizations. The process must be detailed enough so that somebody else can get the same results when applying that. The @other person@ is expected to have IT knowledge sufficient to install and run a Linux desktop. The method must specify the level performance at which the site is considered DEAD. Budget requirements: Low - Dedicated machine + dedicated tester.
