A system includes a plurality of servers and a border server. The border server receives a request for a transaction that can be accomplished by performing tasks, identifies a first task of the tasks, identifies an initial server of the servers to perform the first task by consulting, based on a type of the first task, routing data stored in memory of the border server, and requests that the initial server perform the first task. Each of the servers will, in response to receiving a task from the border server, perform the received task using related data stored exclusively on the server, determine whether the received task requires an additional task, identify a next server to perform the additional task by consulting routing data stored in memory of the server, and request that the next server perform the additional task.
