Abstract
The ability to maintain consistent high availability is becoming an essential attribute of software. To this end, several COTS software products that provide fault tolerance and disaster recovery have recently begun to attract the attention of interested system administrators. In this technical note, we evaluate and compare two such products, namely Marathon everRun and DataGardens Wave. EverRun provides fault tolerance by running replicas of system components or of the entire system in parallel of the main instance. Wave creates a backup image of a virtualized resource, which can be used for fault tolerance or disaster recovery. Both products provide interesting added value to critical systems, for which availability is a preeminent concem.
