Software Aging and Rejuvenation in the Cloud: A Literature Review

With cloud computing becoming pervasive in IT enterprises, the long-running performance of cloud-based applications and services and of the underlying virtualization systems is a paramount concern. Researchers have been studying the phenomenon of software aging, and the corresponding rejuvenation countermeasures, in cloud-related contexts since about 10 years. This paper reviews the effort conducted so far by the software aging and rejuvenation (SAR) community in the cloud domain. Figures about current research trends and future directions can be derived from the reported results.
