Resiliency in a cloud-based storage system
Data resiliency in a cloud-based storage system, including: receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data; generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data; and storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the generated self-describing information for recoverability of the one or more shards of data.
1. A method comprising:
receiving, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data;
generating, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data, the self-describing information for recoverability including information about distribution of the one or more shards in the cloud-based storage system and redundancy information; and
storing, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the self-describing information for recoverability of the one or more shards of data, the self-describing information for recoverability of a shard of data generated before the shard is stored in the second tier of cloud storage.
2. The method of claim 1 , wherein the received one or more segments of data are included within one or more blocks of data.
3. The method of claim 1 , wherein the first tier of cloud storage includes a plurality of cloud computing instances that include respective storage capacity.
4. The method of claim 3 , wherein the first tier of cloud storage is block-level storage.
5. The method of claim 1 , wherein the second tier of cloud storage includes an object storage.
6. The method of claim 5 , wherein the first tier of cloud storage includes a level of storage granularity that is block-level, and wherein the storing the one or more shards of data includes transferring the one or more shards of data from block-level storage in the first tier of cloud storage to object storage in the second tier of cloud storage.
7. The method of claim 1 , wherein the first tier of cloud storage of the cloud-based storage system stores a subset of a volume of data.
8. The method of claim 7 , wherein the second tier of cloud storage of the cloud-based storage system stores all portions of the dataset.
9. The method of claim 1 , wherein the one or more segments are part of a dataset, and wherein the cloud-based storage system synchronously replicates the dataset with one or more other storage systems.
10. The method of claim 9 , wherein the one or more other storage systems include a hardware-based storage system.
11. A cloud-based storage system within a cloud computing environment, the cloud-based storage system including:
one or more cloud computing instances providing a first tier of cloud storage;
a second tier of cloud storage; 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 to:
receive, for storage within a first tier of cloud storage of the cloud-based storage system, one or more segments of data;
generate, for each of one or more shards of data of the one or more segments of data, self-describing information for recoverability of the one or more shards of data, the self-describing information for recoverability including information about distribution of the one or more shards in the cloud-based storage system and redundancy information; and
store, within a second tier of cloud storage of the cloud-based storage system, both the one or more shards of data and the self-describing information for recoverability of the one or more shards of data, the self-describing information for recoverability of a shard of data generated before the shard is stored in the second tier of cloud storage.
12. The cloud-based storage system of claim 11 , wherein the first tier of cloud storage of the cloud-based storage system stores a portion of the dataset.
13. The cloud-based storage system of claim 11 , wherein the first tier of cloud storage of the cloud-based storage system includes one or more cloud computing instances.
14. The cloud-based storage system of claim 11 , wherein the second tier of cloud storage of the cloud-based storage system stores all portions of the dataset.
15. The cloud-based storage system of claim 11 , wherein the second tier of cloud storage of the cloud-based storage system includes a cloud object store.
16. The cloud-based storage system of claim 11 , wherein the received one or more segments of data are included within one or more blocks of data.
17. The cloud-based storage system of claim 11 , wherein the first tier of cloud storage includes a level of storage granularity that is block-level, and wherein the storing the one or more shards of data includes transferring the one or more shards of data from block-level storage in the first tier of cloud storage to object storage in the second tier of cloud storage.
18. The cloud-based storage system of claim 11 , wherein the one or more segments are part of a dataset, and wherein the cloud-based storage system synchronously replicates the dataset with one or more other storage systems.
19. The cloud-based storage system of claim 18 , wherein the one or more other storage systems include one or more hardware-based storage systems.
20. The cloud-based storage system of claim 18 , wherein the one or more other storage systems include one or more cloud-based storage systems.
