Reliability, Fault Tolerance, and Quality-of-Service in Cloud Computing

Abstract

In this chapter we are focusing on reliability, fault tolerance and quality of service in cloud computing. The flexible and scalable property of dynamically fetching and relinquishing computing resources in a cost-effective and device-independent manner with minimal management effort or service provider interaction the demand for Cloud computing paradigm has increased dramatically in last few years. Though lots of enhancement took place, cloud computing paradigm is still subject to a large number of system failures. As a result, there is an increasing concern among community regarding the reliability and availability of Cloud computing services. Dynamically provisioning of resources allows cloud computing environment to meet casually varying resource and service requirements of cloud customer applications. Quality of Service (QoS) plays an important role in the affective allocation of resources and has been widely investigated in the Cloud Computing paradigm.
