Disturbance-free partitioning and migration of data from one storage account to another storage account

A method for data migration, comprising:

• initially processing, by an operating system executing on a computer device, requests from a plurality of geographic regions for a cloud service using a global back-end service with a global storage account storing data from a plurality of geographic regions, wherein the global back-end service includes a global replicated table (“RTable”);
• establishing a region back-end service with a region storage account in at least one geographic region of the plurality of geographic regions to support the cloud service for users in the at least one geographic region, wherein the region back-end service includes a region RTable;
• receiving, by the region back-end service, user requests for the cloud service from one or more users in the at least one geographic region;
• accessing, via the region RTable, one or more rows of data associated with the at least one geographic region from the global storage account in response to the user requests;
• locking, by the global RTable, the one or more rows of data associated with the at least one geographic region in the global storage account during replication of the one or more rows of data in response to the access;
• replicating the one or more rows of data accessed by the region RTable into the region storage account;
• and
• updating a configuration to inactivate the one or more rows of data associated with the at least one geographic region in the global storage account in response to a conclusion of the access to the one or more rows of data associated with the at least one geographic region by the region RTable in response to the user requests.

A computer-readable medium storing instructions executable by a computer device, comprising:

• at least one instruction for causing the computer device to initially process requests from a plurality of geographic regions for a cloud service using a global back-end service with a global storage account storing data from a plurality of geographic regions, wherein the global back-end service includes a global replicated table (“RTable”);
• at least one instruction for causing the computer device to establish a region back-end service with a region storage account in at least one geographic region of the plurality of geographic regions to support the cloud service for users in the at least one geographic region, wherein the region back-end service includes a region RTable;
• at least one instruction for causing the computer device to receive, by the region back-end service, user requests for the cloud service from one or more users in the at least one geographic region;
• at least one instruction for causing the computer device to access, via the region RTable, one or more rows of data associated with the at least one geographic region from the global storage account in response to the user requests;
• at least one instruction for causing the computer device to lock, by the global RTable, the one or more rows of data associated with the at least one geographic region in the global storage account during replication of the one or more rows of data in response to the access;
• at least one instruction for causing the computer device to replicate the one or more rows of data accessed by the region RTable into the region storage account;
• and
• at least one instruction for causing the computer device to update a configuration to inactivate the one or more rows of data associated with the at least one geographic region in the global storage account in response to a conclusion of the access to the one or more rows of data associated with the at least one geographic region by the region RTable in response to the user requests.
