Provisioning storage resources for customers from a distributed grid of disparate storage systems is presented herein. A storage tier component can sort, based on attributes of heterogeneous computer-readable storage media, the heterogeneous computer-readable storage media into tiers of storage to facilitate provisioning a portion of storage space of a tier of the tiers for a computing resource. Further, the storage tier component can receive an input from a device for provisioning of the portion of the storage space of the tier, and configure, based on the input, a storage resource to facilitate access between the portion of the storage space of the tier and the computing resource. Furthermore, a tracking component can create an account associated with a customer that is associated with the device to facilitate tracking and/or limiting of utilization of the portion of the storage space of the tier by the customer.
