Unified transaction services for multi-tenant architectures

A non-transitory machine-readable medium having instructions stored thereon, the instructions executable to cause performance of operations comprising:

• receiving a request, at a first service provider, to provide a first transaction service for a user;
• accessing a first representation of the first service provider in a first hierarchical data structure, the first hierarchical data structure being managed by a second service provider, the second service provider managing a user identity of the user;
• determining, based on the first representation, that transaction resources required for completion of the first transaction service are provided at the second service provider using a resource representation;
• responsive to determining that the transaction resources are accessible at the first service provider, accessing, at the first service provider, the transaction resources via the resource representation;
• determining a user representation of the user at a third service provider, the third service provider modeling a social graph of connections between the user and a plurality of users;
• and
• processing, using the social graph, the first transaction service.

A device, comprising:

• a non-transitory memory storing instructions;
• and
• a processor configured to execute the instructions to cause the device to:
• receive a request, at a first service provider, to provide a first transaction service for a user;
• access a first representation of the first service provider in a first hierarchical data structure, the first hierarchical data structure being managed by a second service provider, the second service provider managing a user identity of the user;
• in response to the accessing and based on a determination that the first transaction provider includes transaction resources for completing the first transaction service, generate a resource representation at the second service provider with a link to the first service provider;
• determine, based on the first representation, that transaction resources required for completing the first transaction service are provided at the second service provider using a resource representation;
• and
• responsive to determining that the transaction resources are accessible at the first service provider, access, at the first service provider, the transaction resources via the resource representation.
