Stimulating Failure Scenario for CLB

Now for testing if the load to our EC2 web-server is getting equalling distributed or not let’s login to EC2 instance created and change the content of index.html page
First login to CLB-instance-1 and run following
[code]sudo su
echo "Hello World From CLB-Instance-1" /var/www/html/index.html[/code]

This will change the Hello World page to Hello World From CLB-Instance-1
Similarly on second instance
[code]sudo su
echo "Hello World From CLB-Instance-2" &amp;gt; /var/www/html/index.html[/code]

This will change the Hello World page to Hello World From CLB-Instance-2
Now if you hit CLB DNS name should see traffic getting server from two different (do few browser refresh F5)
Now from simulting the error scenerio lets remove health.html from CLB-instance-1, doing this since we have defined health.html page as our health check file
Run following commands on CLB-instance-1

[code]cd /var/www/html
rm health.html[/code]
Now if you hit CLB DNS name and hit few refresh on browser you should traffic getting server only from one instance
And in CLB instance tab, CLB-instance-1 is marked OutOfService
Delete everything now!
