Enhancing cloud computing reliability using efficient scheduling by providing reliability as a service

Cloud computing is one of the prime need of today´s IT world. Organizations are shifting to the cloud rapidly in order to increase their overall benefits. Cloud computing has virtualization as its backbone. Cloud resources are provided on demand using the Internet and an on-running migration of resources is done by the cloud service provider. Failure is the nature of hardware and same for the software. Therefore, cloud resources can also fail at any time and leave impact on the performance of the other resources. That is why; it is required for cloud computing to incorporate a monitoring system. In a dynamic computing environment like cloud computing, it is hard to maintain and analyse the reliability of the resources. As cloud is a combination of different resources acting together to provide services to the end users, Virtual machines are the key to provide the Infrastructure as a Service (IaaS) to these end users. In this paper a novel attempt is made to propose a reliability computing technique to calculate the reliability of a Cloud data centre. Further, in this paper we have proposed a mechanism for continuous updating of cloud resources´ reliability and providing a reliable scheduling of the resources to the cloud users in a cloud computing environment.
