Preparation
1. Ensure App.Config has correct 5 minute sendTimeout values “00:05:00” for each service.
2. Login to AWS Educate.
3. Ensure each scale group has the following values:

b. desired = 1 c. max=4
4. At this time there should only be one VM per scale group.
a. Ensure that each of these VMs is running and 2/2 status checks completed.
b. Login to each of these three VMs, start the Task Manager, and display the
Performance in the Task Manager (see image below). For each of the three VMs,
• simply place a Task Manager at the top-left corner of the VM’s desktop, • then resize this desktop.
5. Test run your AT2 program to ensure that your WCF operations execute on these three VMs (see example image below).

c. TestXLarge.cff
3. Scale Groups X 3
a. VM Health
c. Scale policy
i. scale-out at 70%
ii. scale-in enabled
4. Launch Configuration X 3

Application – Asynchronous operations
show code to indicate a 2nd thread to call several WCF operations per target
run program; while the GUI thread waits, show CPU performance of each VM as operations execute
Application – GUI thread waits
show no control of GUI while waiting for operations to complete
Application – 5 minute deadline
display sendTimeout values in App.Config
display try/catch code within your completed event handler
run your program after updating sendTimeout in App.Config to 0 seconds to increase the number of late arrivals and failed attempts, your GUI might display something like:
10. Cloud a.
11. Cloud a. b. c.

12. Cloud Application – concurrent WCF operations on each VM
a. for each VM, show that several operations are executing concurrently
