Methods and architectures for implementing a fault tolerant real time event processing system are provided. The system includes at least one satellite and at least one primary data center. The system remains operational when the primary data center is unavailable to the satellite. The system includes business logic that is divided into logic that can be run effectively at a satellite, and logic that can be run at the main data center to result in effective decisions. When the network connection is impaired or the main data center is unavailable, the satellite can process an incoming event locally. The system includes procedures so that events processed at a satellite during a period of noncommunication with the primary data center will be entered into the primary data center records at a later point.
