This paper introduces four layers of cloud storage architecture： data storage layer （connecting multiple storage components）, data management layer （providing common support technology for multiple services）, data service layer （sustaining multiple storage applications）, and user access layer. A typical cloud storage application--Backup Cloud （B-Cloud）--is examined and its software architecture, characteristics, and main research areas are discussed.展开更多

ACS was first introduced by IBM to create systems capable of managing automatic self-configuration, self-healing, self-optimization and self-protection. These systems detect errors that cause failure, and then recover and reconfigure itself. The concept is wildly adapted by many software applications that have many restoring and recovery functionality such as operating systems (e.g. Windows Server 2012). This paper proposes a cloud ACS (CACS) for cloud computing environment that monitors, diagnoses, checks and heals cloud applications automatically and immediately with almost unnoticeable recovery time. In order to evaluate CACS, an application has been developed and applied for real time cloud applications. The results of different experiments scenarios demonstrate the ability of adopting the proposed system to heal well cloud applications. CACS is also compared with Windows Server 2012 operating system in terms of healing ability, speed, cost, methodology and other informative information. CACS showed domination in almost all of these properties.展开更多
