A networked computational architecture for provisioning of virtualized computational resources. The architecture is accessible by a client application run on a client device. The architecture includes a hardware layer having a plurality of server devices, each server device having at least one physical processor having a local memory. A resource controller is provided and operable to allocate a plurality of server devices to a client application for data processing and to assign control information to the client application. The control information specifies the required allocation of a data processing workload to each server device allocated to the client application. The architecture is configured such that client applications send the data processing workload directly to each server in accordance with the control information. Thus, a networked architecture is load balanced indirectly without requiring a load balancer to be located in the data path between the client and the server.
