Methods, systems, and computer-readable storage media for sharing of data between tenants associated with network applications. A set of queues related to a set of tenants at a plurality of platforms is maintained. Each queue stores a set of messages related to events generated by a particular tenant from the set of tenants. Each queue of is divided into a respective subset of sub-queues. Each sub-queue of the respective subset of sub-queues is associated with a particular topic. Access control permissions and network connections defined for each tenant of the set of tenants are evaluated. Data federation logic is executed to distribute data from a first sub-queue of a first queue associated with a first tenant of the set of tenants to at least one other sub-queue of a second queue associated with a second tenant based on at least one matching topic defined in the data federation logic.
