Moving Data Between Tiers In A Multi-Tiered, Cloud-Based Storage System

A cloud-based storage system including:

• a first tier of cloud storage provided using a first cloud storage service;
• a second tier of cloud storage provided using a second cloud storage service;
• and
• one or more storage controller applications, each storage controller application executing in a cloud computing instance, wherein the one or more storage controllers are configured for:
• receiving a data storage operation from a computer device;
• storing data corresponding to the data storage operation within the first tier of cloud storage provided using the first cloud storage service;
• and
• responsive to detecting a condition for transferring data between the first tier of cloud storage and the second tier of cloud storage, transferring the data in the first tier of cloud storage to a second tier of cloud storage provided using a second cloud storage service, wherein the first cloud storage service is different than the second cloud storage service.

A computer program product disposed on a non-transitory computer readable medium, the computer program product including computer program instructions that, when executed, carry out the steps of:

• receiving, by a storage controller application executing on cloud computing resources in a cloud-based storage system, a data storage operation from a computer device, wherein the cloud-based storage system includes a first tier of cloud storage and a second tier of cloud storage;
• storing data corresponding to the data storage operation within the first tier of cloud storage provided using a first cloud storage service;
• and
• responsive to detecting a condition for transferring data between the first tier of cloud storage and the second tier of cloud storage, transferring the data in the first tier of cloud storage to a second tier of cloud storage provided using a second cloud storage service, wherein the first cloud storage service is different than the second cloud storage service.
