Partitioned deployment of updates to cloud service based on centerally updated configuration store

A cloud-based service for deploying an update of the cloud-based service to a plurality of users of the cloud-based service, comprising:

• an update execution unit comprising:
• a policy importer unit for obtaining policy information for the update to be deployed to one or more components of the cloud-based service, the policy information identifying a plurality of rings, each comprised of a group of the users of the cloud-based service, to which the update is to be deployed;
• a configuration update unit coupled to the policy importer unit for receiving and analyzing the policy information to determine configuration information for a plurality of installer instances provided in the update execution unit, wherein each installer instance is associated with one or more of the plurality of rings or one or more stages of one of the plurality of rings to which the update is to be deployed;
• and
• a deployment database coupled to each installer instance of the plurality of installer instances to provide payload information for each respective installer instance of the plurality of installer instances, the payload information indicating one or more payloads associated with the update to be deployed to the respective one or more rings or one or more stages of the ring associated with the respective installer instance,
• wherein each respective installer instance, upon receiving the payload information, deploys the one or more payloads, associated with the respective installer instance, for each of the one or more rings or the one or more stages of the ring associated with the respective installer instance;
• and
• a reporting and feedback unit, coupled to the update execution unit, for reporting to the update execution unit whether the update to the users has been successful or a regression occurred during the update,
• wherein:
• upon determining from the reporting and feedback unit that a first payload deployed to a first ring or stage of a first ring has included a regression, the configuration update unit:
• deactivates a first installer instance associated with the first ring or stage upon determining the first payload included the regression;
• adjusts a ring boundary associated with a second installer instance to include the one or more rings or the one or more stages of the ring associated with the first installer instance;
• and
• deploys a second payload associated with the second installer instance to the one or more rings or the one or more stages of the ring associated with the first installer instance.
