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.

Abstract: Technologies are described for updating a live system with static changes. According to some examples, changes such as installing and/or removing features may be applied to a cloud based service in live environment without disrupting the service. New software may be patched and installed on an upgraded machine (i.e., server). New features, diagnostics, and language packs may be added. Existing features and certificates may be removed. To accomplish these, new software to be installed and existing software to be removed may be detected. Removal and additions may be performed without preparation and activation of replacement farms.
