Taking this part.

@marpierc @smarru Hello professors, I was trying to set up an autoscale group in AWS, but looks like I do not have permissions to do so. I could configure the settings, but the AWS wizard fails when "Creating launch configuration Failure" I am also unable to see the AutoScaling group dashboard which leads me to believe it is a permission issue.

The Autoscale group is setup and running in Ohio.

One question which popped in my mind regarding spot instance is, considering the fact that these can get shutdown anytime and the Autoscale group will try to get another EC2 instance - We need a way to initialize this newly spawned EC2 instance with our application.

I know that on next deployment trigger, our application will get deployed to this instance. But prior to that we will be down 1 service inspite of having a Box up and running.
