Dynamic Cache Allocating Techniques for Cloud Computing Systems

A non-transitory computer readable storage media encoded with instructions that, when executed by a computer, cause the computer to perform operations comprising:

• storing information for a spot price of a cache of a storage infrastructure used for data storage in a cloud computing environment, the spot price representing a variable price per memory size allocation for use of the cache of the storage infrastructure and being determined based on supply and demand of the cache;
• receiving a request for allocation of additional cache for use by one or more applications associated with a first tenant running in the cloud computing environment;
• sending to the one or more applications information indicating a current spot price of the cache of the storage infrastructure;
• receiving from the one or more applications an instruction to purchase the allocation of additional cache based on the current spot price or based on a predetermined fixed price;
• and
• sending to the storage infrastructure an allocation request for allocation of the additional cache based on the current spot price or the predetermined fixed price.

A system comprising:

• a storage infrastructure subsystem including at least one storage array and non-volatile cache memory;
• a compute subsystem running one or more applications associated with a first tenant, wherein the compute subsystem interfaces with the storage infrastructure subsystem;
• and
• a processor that is communication with the storage infrastructure subsystem and the compute subsystem, wherein the processor:
• stores information for a spot price of the cache memory, the spot price representing a variable price per memory size allocation for use of the cache memory determined based on supply and demand of the cache memory;
• receive a request for allocation of additional cache for use by one or more applications associated with a first tenant running in the cloud computing environment;
• cause information indicating a current spot price of the cache memory to be sent to the one or more applications;
• receive from the one or more applications an instruction to purchase the allocation of additional cache memory based on the current spot price or based on a predetermined fixed price;
• and
• cause to be sent to the storage infrastructure subsystem an allocation request for the allocation of additional cache memory based on the current spot price or the predetermined fixed price.
