• instructions executable by the processor to cause the processor to perform, via a duplicate of the primary match server that performs each operation, of a sequence of operations to be performed by the primary match server, subsequent to the operation being successfully completed by the primary match server or after determination that the primary match server will not successfully do so.

A system for providing fault tolerance to a primary match server, the system comprising:

• a processor;
• a memory coupled with the processor;
• first logic stored in the memory and executable by the processor to cause the processor to perform, via a duplicate of the primary match server that performs each operation, of a sequence of operations to be performed by the primary match server, subsequent to the operation being successfully completed by the primary match server or after determination that the primary match server will not successfully do so.

A computer implemented system for providing fault tolerance to a primary match server means, the system comprising a processor and further comprising:
