According to one aspect of the present disclosure, a method and technique for data processing in a distributed computing system having a service-oriented architecture is disclosed. The method includes: receiving, by a workload input interface, workloads associated with an application from one or more clients for execution on the distributed computing system; identifying, by a resource management interface, available service hosts or service instances for computing the workloads received from the one or more clients; responsive to receiving an allocation request for the one or more hosts or service instances by the workload input interface, providing, by the resource management interface, address information of one or more workload output interfaces; and sending, by the one or more workload output interfaces, workloads received from the workload input interface to the one or more service instances.
