Nowadays, virtualized platforms have become the most popular option to deploy complex enough services. The reason is that virtualization allows resource providers to increase resource utilization. Deployed services are expected to be always available, but these long-running services are especially sensitive to suffer from software aging phenomenon. This term refers to an accumulation of errors, which...
Software aging often affects the performance of a software system and eventually causes it to fail. To highlight the aging problems in long running applications, we have conducted the study of software rejuvenation approach and virtualization technology in this paper. In order to reduce the downtime during rejuvenation interval, software rejuvenation and virtualization technology are combined in this...
In this paper, we present an approach for software rejuvenation based on automated self-healing techniques that can be easily applied to off-the-shelf application servers. Software aging and transient failures are detected through continuous monitoring of system data and performability metrics of the application server. If some anomalous behavior is identified, the system triggers an automatic rejuvenation...
Software aging effects if left uncontrolled are known to cause availability issues. When an application is serving live in production, fixing such issues is close to impossible. Software rejuvenation techniques can be used effectively to avoid failure, but will incur some downtime if a single instance of the application is running. With two instances the system can be engineered in such a way that...
