Abstract
|
Fault and intrusion tolerance is an import … Fault and intrusion tolerance is an important paradigm for building
distributed systems that work in spite of accidental and malicious
faults. This paper discusses how to harness virtualization technology
for building such dependable systems. We show that virtualization
promotes a hybrid fault model that allows tolerating malicious
intrusions in application domains with little overhead. The
proposed architecture features mechanisms for supporting heterogeneity
of the replicas. A hypervisor-based replication controller
achieves perpetual operation through periodic proactive recovery
of the replicas. Re-mapping of state storage between virtual machines
speeds up the state transfer of a stateful replicated service.
Our VM-FIT prototype implements the core functionality of such
a virtualization-based replication architecture. We present some
performance measurements and close with a discussion of future
research directions. discussion of future
