    Towards Reliable Mobile Cloud Computing
    (IEEE, 2015) Darwish, Khaled O.; El Madahh, Islam; Mohamed, Hoda K.; El Hennawy, Hadia
    Cloud computing has been one of the fastest growing components of the IT industry. It altered the future of the web by having computing, communication, and storage provides as services to internet users. Mobile Cloud Computing (MCC) is currently gaining steam as an extension to cloud computing as it delivers a large variety of cloud application to billions of smartphones and wearable devices. This paper studies reliability for MCC by determining the ability of a system component to function correctly under different scenarios for a specified period of time. Our aim is to be able to estimate and manage uncertainty and risks of failure. The assessment procedures consist of determine Mean Time between Failures (MTBF), Mean Time to Failure (MTTF), and availability percentages for main components in both cloud computing and MCC structures applied on single node OpenStack installation to analyze its performance with different settings governing the behavior of participants. Additionally, we present here several factors with significant impact on the overall cloud system reliability that should be taken into account in order to deliver highly available cloud computing services for mobile consumers.
