Abstract
This work proposes the adoption of Autonomic Computing System (ACS) in Cloud environment. 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.
Highlights
The wide and fast spread of Internet motivated large number of companies to adopt the cloud solution and offer their services and business online, i.e. through the World Wide Web (WWW)
This paper proposes a solution to such problem and many others by applying cloud ACS (CACS) that has the functionality of self-healing, self-monitoring, self-diagnosis and self-recovering to keep the cloud application in good health!
What advantages can we get when using CACS to heal cloud applications that are affected by different performance scenarios?
Summary
The wide and fast spread of Internet motivated large number of companies to adopt the cloud solution and offer their services and business online, i.e. through the World Wide Web (WWW). Cloud ACS (CACS) applications require a 24/7 auto-monitoring of the applications as well as a fast recovery mechanism that keeps the online functionality and service of applications offered to customers available all the time. This paper proposes a solution to such problem and many others by applying CACS that has the functionality of self-healing, self-monitoring, self-diagnosis and self-recovering to keep the cloud application in good health!. Software systems have many anomalous conditions that appear among the components of software systems To handle such situations the software architecture for this purpose has been splitted into two layers: functional layer and healing layer. In summary the research defines a mechanism for an external self-healing software application that monitors, diagnoses and detects a failure automatically and efficiently. The reset of this paper is organized as follows: Section two presents related work on ACS, and the mechanisms that are used for recovering different application; Section three presents a full description of the proposed system; Section four demonstrates the evaluation experiments and discusses their results; and Section five provides the conclusion and future work
