US Patent 11061929 Replication of resource type and schema metadata for a multi-tenant identity cloud service

Embodiments operate a multi-tenant cloud system with a first data center. At the first data center, embodiments authenticate a first client and store resources that correspond to the first client, the first data center in communication with a second data center that is configured to authenticate the first client and replicate the resources. In response to upgrading global resources at the first data center to a new version, embodiments generate a manifest file including a listing of global resource types and schemas that are modified or added in response to the upgrading. Embodiments further upgrade global resources based on the manifest file and write the upgraded global resources to a first global database and generate change event messages corresponding to the upgraded global resources.
