Gateways for Accessing Fault Tolerance Domains [chapter]

P. Narasimhan, L. E. Moser, P. M. Melliar-Smith
2000 Lecture Notes in Computer Science  
Enterprise applications can be structured as domains, where each domain contains objects that are replicated for fault tolerance, with the replication being managed by a fault tolerance infrastructure  ...  Gateways can allow unreplicated clients to benefit from the fault tolerance services of the replicated servers, without compromising replica consistency within the fault tolerance domain.  ...  Unreplicated objects outside the fault tolerance domain must never be allowed to access the replicated objects within the fault tolerance domain directly.  ...
