Despite the fact that cloud computing offe … Despite the fact that cloud computing offers a high degree of dynamism on resource provisioning, there is a general lack of support for managing dynamic adaptations of replicated services in the cloud, and, even when such support exists, it is focused mainly on elasticity by means of horizontal scalability. We analyse the benefits a replicated service may obtain from dynamic adaptations in the cloud and the requirements on the replication system. For example, adaptation can be done to increase and decrease the capacity of a service, move service replicas closer to their clients, obtain diversity in the replication (for resilience), recover compromised replicas, or rejuvenate ageing replicas. We introduce FITCH, a novel infrastructure to support dynamic adaptation of replicated services in cloud environments. Two prototype services validate this architecture: a crash fault-tolerant Web service and a Byzantine fault-tolerant key-value store based on state machine replication. store based on state machine replication.
