Policy-based optimization of cloud resources on tiered storage operations

A system for allocating cloud resources in a cloud computing system based on tiered storage data movement, the method comprising:

• one or more computing nodes having a memory and a processor;
• and
• a non-transitory computer readable storage medium of the one or more computing nodes having program instructions embodied therewith, the program instructions executable by the processor to cause the system to:
• transmit a request to a tiered storage system to provide a notification of a data movement initiated by a tiered storage system, wherein:
• the data movement comprises moving data associated with the cloud computing system from a first storage tier to a second storage tier, and the notification comprises an indication of a condition for initiating the data movement, and
• the condition comprises an indication that a utilization of the tiered storage system exceeds a subscribed utilization level;
• receive the notification from the tiered storage system;
• identify, using the received notification, a hosted computing environment having a volume associated with the data movement;
• determine that a condition for initiating the data movement is satisfied;
• determine, based on the determination that the condition is satisfied, whether to change an allocation of resources to the hosted computing environment;
• and
• change the allocation of resources to the hosted computing environment response to determining to change the allocation of resources to the hosted computing environment.

A computer program product for allocating cloud resources in a cloud computing system based on tiered storage data movement, the computer program product including a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processing circuit to cause the processing circuit to perform a method comprising:

• transmitting a request to a tiered storage system to provide a notification of a data movement initiated by a tiered storage system, wherein:
• the data movement comprises moving data associated with the cloud computing system from a first storage tier to a second storage tier, and
• the notification comprises an indication of a condition for initiating the data movement;
• and
• the condition comprises an indication that a utilization of the tiered storage system exceeds a subscribed utilization level;
• receiving the notification from the tiered storage system;
• identifying, using the received notification, a hosted computing environment having a volume associated with the data movement;
• determining that a condition for initiating the data movement is satisfied;
• determining, based on the determination that the condition is satisfied, whether to change an allocation of resources to the hosted computing environment;
• and
• changing the allocation of resources to the hosted computing environment response to determining to change the allocation of resources to the hosted computing environment.
