Multiple Fault-Tolerance Mechanisms in Cloud Systems: A Systematic Review
Philippe Marcotte, Frederic Gregoire, Fábio dos Santos Petrillo · 2019
Cloud systems are progressively taking over today's software market. These typically require constant operations with a minimum of failure. Multiple fault-tolerance mechanisms have been developed to maximize the availability of cloud systems. In this paper, we propose a systematic review of the literature on fault-tolerance mechanisms. We discussed the current trends, and we found that migration, checkpointing and replication are the most widely used based on the number of references. In contrast, some mechanism like task resubmission and n-version programming seems to incur less research.
