Hi,

I recently started working on Amazon services, and currently started knowing Amazon EMR. I am more or less familiar with openstack. So, I have a doubt to be clarified. In openstack we have controller, compute and cinder. Can some1 please tell me the equivalents in using Amazon EMR. Like the storage in EMR is S3 and storage in openstack is Cinder. So whats for compute and controller. I know they are servers supported by amazon, but can some1 please put it in words.

Thanks a ton.
