REFIT: Resource-Efficient Fault and Intrusion ToleranceInternet-based services play a central role in today's society. With such
services progressively taking over from traditional infrastructures, their
complexity steadily increases. On the downside, this leads to more and more
faults occurring. As improving software-engineering techniques alone will not
do the job, systems have to be prepared to tolerate faults and intrusions.REFIT investigates how systems can provide fault and intrusion tolerance in a
resource-efficient manner. The key technology to achieve this goal is
virtualization, as it enables multiple service instances to run in isolation on
the same physical host. Server consolidation through virtualization not only
saves resources in comparison to traditional replication, but also opens up
new possibilities to apply optimizations (e.g., deterministic multi-threading). Resource efficiency and performance of the REFIT prototype are evaluated
using a web-based multi-tier architecture, and the results are compared to
non-replicated and traditionally-replicated scenarios. Furthermore, REFIT
develops an infrastructure that supports the practical integration and
operation of fault and intrusion-tolerant services; for example, in the context
of cloud computing.
