Recent years have seen the massive migration of enterprise applications to the cloud. One of the challenges posed by cloud applications is Quality-of-Service (QoS) management, which is the problem of allocating resources to the application to guarantee a service level along dimensions such as performance, availability and reliability. This paper aims at supporting research in this area by providing a survey of the state of the art of QoS modeling approaches suitable for cloud systems. We also review and classify their early application to some decision-making problems arising in cloud QoS management.

Abstract-The need for uninterrupted computing services demands for high system availability and reliability. Techniques and methods to estimate and analyze system dependability are essential to support software deployment and maintenance. Soft-ware aging appears as a relevant issue in this context. Software aging is a cumulative process which leads long-running systems to hangs or failures. Software rejuvenation is used to counteract software aging. Software rejuvenation usually comprises system reboot or application restart to bringing software to a stable fresh state. This paper proposes an approach to investigate software aging effects and software rejuvenation effectiveness on a single experiment. The approach has three phases: (i) Stress Phase -stress environment with the accelerated workload to induce bugs activation; (ii) Wait Phase -stop workload submission to observe the system state after workload submission; (iii) Rejuvenation Phase -find the impacts caused by the software rejuvenation. We named our approach as SWARE (Stress-Wait-Rejuvenation). To validate the SWARE approach, we present a case study. This case study consists of an experiment of VM Live Migration as rejuvenation mechanism for VMM software aging. The considered testbed is a Private Cloud with OpenNebula and KVM 1.0. The obtained results show that VM live migration is useful as rejuvenation for VMM software aging.

“…Due to system downtime caused by software rejuvenation, a proper approach is to conduct software rejuvenation with scheduling. Some papers [18], [19] show that very often migrations can reduce system availability significantly.…”

“…Since the aging effects are typically caused by hard to track software faults, rejuvenation techniques look for reducing the aging effects during the software runtime, until the aging causes (e.g., a software bug) are fixed definitively. In general, software rejuvenation mechanisms are based on system restart or OS reboot [18]. Due to system downtime caused by software rejuvenation, a proper approach is to conduct software rejuvenation with scheduling.…”

Many researchers around the world are working hard to improve cloud-based services focusing on server-side and communication aspects. This is especially true for services which demand high processing power and storage space on their server's infrastructure, such as live video streaming on the web and video on demand. However, issues on client-side applications are often neglected or studied to a lower extent. In this context, this paper evaluates the occurrence of software aging in a web browser plug-in for video streaming. The case study is carried out by using an automated workload that simulates the user behavior accessing videos on YouTube. Time series were used to predict the resources utilization ahead of time, enabling the prevention of performance degradation and unexpected crashes. Finally, the prediction-based strategy is compared to the time-based strategy, showing the impact of both on system's availability.
