Zusammenfassung:	A system and method enables loosely-coupled lock-step computing including sensors that detect or measure a physical property and server groups. Each server group is serially linked to another server group and includes server instances operating in virtual synchrony. Virtual synchrony middleware receives outputs from multiple server instances and renders a single reply based on the outputs from the multiple server instances. The virtual synchrony middleware replicates and orders incoming requests to the server groups to ensure each of the server instances of that server group receives the same incoming requests in the same order.
