In my view:
- SERVICE ELASTICITY RULES are implemented by the service management
layer on top of the infrastructure clouds. That is the case of
RightScale or the RESERVOIR Service Manager (Nephele by Telefonica I
+D), service management tools grow or shrink the service using the
Cloud API to meet given SLOs. See use case http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/ServiceManagerToControlOfLifecycleOfServicesInTheCloud
by Telefonica I+D (RESERVOIR)
- INFRASTRUCTURE PLACEMENT RULES/POLICIES, such as load balancing or
VM consolidation, are executed internally by the cloud provider in
order to optimize a given metric, and are not exposed to end users.
The user can only define placement constraints as attributes in the VM
definition, for example to specify a geographical location.
Regarding storage management, I understand that is related to image
management, that is the functionality that must be delivered for
enabling cloud infrastructure services (methods to register, upload,
update and download disk images).
