Availability Analysis and Improvement of Software Rejuvenation Using Virtualization
Availability of business-critical application servers is an issue of paramount importance that has received special attention from the industry and academia. To improve the availability of application servers, we have conducted a study of virtualization technology and software rejuvenation that follows a proactive fault-tolerant approach to counter act the software aging problem. We present Mar...
متن کاملAdaptive Software Rejuvenation: Degradation Model and Rejuvenation Scheme
We present a framework of adaptive estimation and rejuvenation of software system performance in the presence of aging sources. The framework specifies that a degradation model not only describe an aging process but also enable the adaptation of model-based performance estimates to on-line measurements of data pertaining to the aging process. The adaptive estimation uses model-based a priori es...
متن کاملAvailability Models for Virtualized Systems with Rejuvenation
As one of core technologies of software rejuvenation, analytical models provide a decision-making basis for implementing rejuvenation. This paper builds analytic models using stochastic reward nets with three different rejuvenation policies: non-rejuvenation, time-based rejuvenation, and time and load-based delay rejuvenation, and presents how system transits from one state into another. The re...
متن کاملA Software Reliability Model for Cloud-Based Software Rejuvenation Using Dynamic Fault Trees
Correctly measuring the reliability and availability of a cloud-based system is critical for evaluating its system performance. Due to the promised high reliability of physical facilities provided for cloud services, software faults have become one of the major factors for the failures of cloud-based systems. In this paper, we focus on the software aging phenomenon where system performance may ...
متن کاملSoftware Rejuvenation Model for Cloud Computing Platform
Cloud computing has emerged as one of the most needed technologies that houses software systems and relevant functional entities resulting in complex, multiuser, multitasking and virtualized environments. However, reliability of such high performance computing systems depends both on hardware and software. Virtualization is the technology that many cloud service providers rely on for efficient ...
