Abstract

Methods, systems, and articles for simultaneously maintaining copies of data in a data center and a cloud computing environment providing network based services. Synchronizing applications monitor modifications to data records made in the data center and the cloud computing environment. The synchronizing applications are also configured to convert modified records from the data center into a format compatible with databases in the cloud computing environment prior to updating the databases in the cloud computing environment, and vice versa.

Claims

1. A computer-implemented method for simultaneously maintaining copies of data in a data center and a cloud computing environment, comprising:

transferring a modified first data record in a first database of the data center to a cloud replicator in the cloud computing environment, wherein the cloud replicator is configured to modify a corresponding data record in a second database of the cloud computing environment in response to receiving the modified first data record;

determining whether a second data record has been modified in the second database; and

upon determining that the second data record has been modified, determining whether a corresponding data record in the first database of the data center should be modified.

2. The method of claim 1, wherein the data record in the first database corresponding to the modified second data record is modified based on at least one business rule for updating databases.

3. The method of claim 2, wherein the at least one business rule comprises updating databases only with most recently modified data.

4. The method of claim 1, wherein the first database and the second database are different types of databases.

5. The method of claim 4, further comprising, modifying the data record in the first database corresponding to the modified second data record, wherein the modification comprises converting the data record into a format compatible with the second database in the data center.

6. The method of claim 1, further comprising transferring the modified first data record upon determining that the first data record has been modified by a network service application.

7. A method for simultaneously maintaining copies of data in a data center and a cloud computing environment, comprising:

receiving a modified first data record from a first database of the data center;

determining whether a second data in the second database should be modified based on the modified first data record; and

upon determining that the second data record should be modified, replicating modifications to the first data record in the second data record, wherein the replicating comprises converting the modified first data record into a format compatible with the second database.

8. The method of claim 7, wherein determining whether the second data record should be modified comprises analyzing at least one business rule for updating databases.

9. The method of claim 8, wherein the at least one business rule comprises updating databases only with most recently modified data.

10. A computer readable storage medium comprising a program product which, when executed is configured to perform an operation for simultaneously maintaining copies of data in a data center and a cloud computing environment, comprising:

transferring a modified first data record in a first database of the data center to a cloud replicator in the cloud computing environment, wherein the cloud replicator is configured to modify a corresponding data record in a second database of the cloud computing environment in response to receiving the modified first data record;

determining whether a second data record has been modified in the second database; and

upon determining that the second data record has been modified, determining whether a corresponding data record in the first database of the data center should be modified.

11. The computer readable storage medium of claim 10, wherein the data record in the first database corresponding to the modified second data record is modified based on at least one business rule for updating databases.

12. The computer readable storage medium of claim 11, wherein the at least one business rule comprises updating databases only with most recently modified data.

13. The computer readable storage medium of claim 10, wherein the first database and the second database are different types of databases.

14. The computer readable storage medium of claim 13, wherein the operation further comprises modifying the data record in the first database corresponding to the modified second data record, wherein the modification comprises converting the data record into a format compatible with the second database in the data center.

15. The computer readable storage medium of claim 10, further comprising transferring the modified first data record upon determining that the first data record has been modified by a network service application.

16. A system, comprising:

a memory device comprising at least one application for simultaneously maintaining copies of data in a data center and a cloud computing environment; and

at least one processor which, when executing the at least one application is configured to;

transfer a modified first data record in a first database of the data center to a cloud replicator in the cloud computing environment, wherein the cloud replicator is configured to modify a corresponding data record in a second database of the cloud computing environment in response to receiving the modified first data record;

determine whether a second data record has been modified in the second database; and

upon determining that the second data record has been modified, determine whether a corresponding data record in the first database of the data center should be modified.

17. The system of claim 16, wherein the first database and the second database are different types of databases.

18. The system of claim 17, wherein the cloud replicator is configured to:

receiving the modified first data record from the first database of the data center;

determining whether a third data in the second database should be modified based on the modified first data record; and

upon determining that the third data record should be modified, replicating modifications to the first data record in the third data record, wherein the replicating comprises converting the modified first data record into a format compatible with the second database.

19. The system of claim 16, wherein the data record in the first database corresponding to the modified second data record is modified based on at least one business rule for updating databases.

20. The system of claim 19, wherein the at least one business rule comprises updating databases only with most recently modified data.
