A method for allocating a device-specific resource from one or more databases, comprising: receiving an initial processing request from a device; generating a device-specific resource based on the device, responsive to the initial processing request; associating a pool identifier with the device and the device-specific resource; generating a coupling identifier based on the pool identifier and a resource identifier; and associating the coupling identifier with data, comprising the device specific resource, in a cached object from the one or more databases; transmitting the coupling identifier to the device, the device being a requesting entity; and subsequently: receiving, at an interface, the coupling identifier including the pool identifier and the resource identifier (262A-1), as part of a processing request from the requesting entity, the processing request including a request for the device-specific resource, wherein the coupling identifier associates the requesting entity with the device-specific resource based on the resource identifier (262A-1); extracting, at the interface, the pool identifier from the coupling identifier; identifying, by the interface, the processing service in which the device-specific resource associated with the resource identifier (262A-1) is cached, based on the pool identifier; and transmitting, from the interface to the identified processing service, at least a part of the processing request to process the cached requested device-specific resource. receiving an initial processing request from a device; generating a device-specific resource based on the device, responsive to the initial processing request; associating a pool identifier with the device and the device-specific resource; generating a coupling identifier based on the pool identifier and a resource identifier; and associating the coupling identifier with data, comprising the device specific resource, in a cached object from the one or more databases; transmitting the coupling identifier to the device, the device being a requesting entity; and subsequently: receiving, at an interface, the coupling identifier including the pool identifier and the resource identifier (262A-1), as part of a processing request from the requesting entity, the processing request including a request for the device-specific resource, wherein the coupling identifier associates the requesting entity with the device-specific resource based on the resource identifier (262A-1); extracting, at the interface, the pool identifier from the coupling identifier; identifying, by the interface, the processing service in which the device-specific resource associated with the resource identifier (262A-1) is cached, based on the pool identifier; and transmitting, from the interface to the identified processing service, at least a part of the processing request to process the cached requested device-specific resource. receiving, at an interface, the coupling identifier including the pool identifier and the resource identifier (262A-1), as part of a processing request from the requesting entity, the processing request including a request for the device-specific resource, wherein the coupling identifier associates the requesting entity with the device-specific resource based on the resource identifier (262A-1); extracting, at the interface, the pool identifier from the coupling identifier; identifying, by the interface, the processing service in which the device-specific resource associated with the resource identifier (262A-1) is cached, based on the pool identifier; and transmitting, from the interface to the identified processing service, at least a part of the processing request to process the cached requested device-specific resource.
