Abstract

Non-limiting examples of the present disclosure describe evaluation of log data of an application/service for the migration of user data to a data center in a geographic region of a user. Log data for the application/service is evaluated over a given time period on a per user basis. Evaluation of the log data comprises determining, for a user, one or more active days within the given time period. An active day comprises one or more call operations made to the application by the user. A primary geographic region of the user may be determined for the given time period based on analysis of the one or more active days of the log data. One or more data centers may be assigned for storage of user data based on the primary geographic region.

Claims

1. A method comprising:

evaluating, over a given time period, log data for a user of an application to determine, for the given time period, a primary geographic region of the user;

assigning, based on the primary geographic region, one or more data centers for storage of user data that is associated with the user;

generating a mapping of the user associated with the assigned one or more data centers;

re-evaluating, over a subsequent time period, log data for the user of the application to determine, for the subsequent time period, whether the primary geographic region of the user has changed;

in response to determining that the primary geographic region of the user has changed;

re-assigning, based on the changed primary geographic region of the user, one or more data centers for storage of user data that is associated with the user; and

updating the mapping of the user associated with the re-assigned one or more data centers.

2. The method of claim 1, wherein the evaluating, over a given time period, log data for the user of the application to determine, for the given time period, the primary geographic region of the user comprises:

determining, for one or more active days, a particular geographic region of the user based on a threshold determination associated with call volume of call operations identified in the log data,

aggregating, over the given time period, geographic region data that corresponds to the particular geographic region for the one or more active days, and

determining, for the given time period, the primary geographic region based on a threshold analysis of the aggregated geographic region data.

3. The method of claim 2, wherein the determining of the primary geographic region further comprises comparing, for the aggregated geographic region data, a threshold value for the given time period with a number of active days that a user is in the particular geographic region, and wherein the assigning assigns the one or more data centers for data storage of the user data when the number of active days for the particular geographic region meets or exceeds the threshold value.

4. The method of claim 2, further comprising confirming the primary geographic region associated with the user based on a determination that a threshold value is unsatisfied, wherein the threshold value is associated with a number of active days that the user is in the particular geographic region for the given time period.

5. The method of claim 2, wherein the determining of the particular geographic region further comprises:

identifying, for the one or more active days of the given time period, an internet protocol (IP) address associated with a largest amount of call volume for call operations of a particular day;

identifying a country associated with the IP address using a mapping that comprises IP address ranges for associated countries; and

mapping, for active days of the given time period, the identified country to the particular geographic region.

6. The method of claim 1, further comprising migrating the user data to the assigned one or more data centers.

7. The method of claim 6, wherein the user data is migrated from another data center located in one selected from a group consisting of:

the primary geographic region and a different geographic region.

8. The method of claim 1, wherein the evaluating, over a given time period, log data for a user of an application further comprises determining one or more active days for the user within the given time period, wherein an active day comprises one or more call operations made to the application by the user.

9. The method of claim 8, wherein the evaluating, over a given time period, log data for a user of an application further comprise determining, for the given time period, a primary geographic region of the user based on an analysis of the one or more active days of the log data.

10. A system comprising:

at least one processor; and

a memory operatively connected with the at least one processor storing computer-executable instructions that, when executed by the at least one processor, causes the at least one processor to execute a method that comprises;

evaluating, over a given time period, log data for a user of an application to determine, for the given time period, a primary geographic region of the user;

assigning, based on the primary geographic region, one or more data centers for storage of user data that is associated with the user;

generating a mapping of the user associated with the assigned one or more data centers;

re-evaluating, over a subsequent time period, log data for the user of the application to determine, for the subsequent time period, whether the primary geographic region of the user has changed;

in response to determining that the primary geographic region of the user has changed;

re-assigning, based on the changed primary geographic region of the user, one or more data centers for storage of user data that is associated with the user; and

updating the mapping of the user associated with the re-assigned one or more data centers.

11. The system of claim 10, wherein the evaluating, over a given time period, log data for the user of the application to determine, for the given time period, the primary geographic region of the user comprises:

determining, for one or more active days, a particular geographic region of the user based on a threshold determination associated with call volume of call operations identified in the log data,

aggregating, over the given time period, geographic region data that corresponds to the particular geographic region for the one or more active days, and

determining, for the given time period, the primary geographic region based on a threshold analysis of the aggregated geographic region data.

12. The system of claim 11, wherein the determining of the primary geographic region further comprises comparing, for the aggregated geographic region data, a threshold value for the given time period with a number of active days that a user is in the particular geographic region, and wherein the assigning assigns the one or more data centers for data storage of the user data when the number of active days for the particular geographic region meets or exceeds the threshold value.

13. The system of claim 11, wherein the executed method further comprises:

confirming the primary geographic region associated with the user based on a determination that a threshold value is unsatisfied, wherein the threshold value is associated with a number of active days that the user is in the particular geographic region for the given time period.

14. The system of claim 11, wherein the determining of the particular geographic region further comprises:

identifying, for the one or more active days of the given time period, an internet protocol (IP) address associated with a largest amount of call volume for call operations of a particular day;

identifying a country associated with the IP address using a mapping that comprises IP address ranges for associated countries; and

mapping, for active days of the given time period, the identified country to the particular geographic region.

15. The system of claim 10, wherein the executed method further comprises:

migrating the user data to the assigned one or more data centers.

16. The system of claim 15, wherein the user data is migrated from another data center located in one selected from a group consisting of:
