  • Shutting down

    The instances screen will show you that your EC2 instance(s) is (are) now shutting down.

  • Terminated

    An instance's state will change to terminated once it has been fully shut down and de-provisioned.  From this point on, you won't be billed.

    You can repeat this entire procedure any time you want to do some Hadoop work.  EMR clusters are available on-demand and you can shut them down as soon as you're done using them.

    For a more permanent cloud-based cluster, you can provision raw EC2 instances, installing Hadoop on them yourself and federating them into a cluster.

    Cloud-based, on-demand Hadoop cluster services comparable to AWS EMR will soon be avaiable from Microsoft, Google and Rackspace, leaving fodder for future galleries here on ZDNet.
