Systems and methods may include providing a first silo configured to operate a first set of event-driven processing stages, and a second silo configured to operate a second set of event-driven processing stages; arranging at least one shared transaction cache between the first set of processing stages and the second set of processing stages of the respective first and second silos, where each processing stage of the first and second sets of processing stages can obtain or receive one or more transactions from the at least one shared transaction cache for processing, and where when a distressed processing stage in the first silo fails to process a first transaction designated for the distressed processing stage in a predefined amount of time, a non-distressed processing stage in the second silo obtains or receives the first transaction from the at least one shared transaction cache to process the first transaction on behalf of the distressed processing stage.
