Management and Scheduling of Resources along with their Optimal Usage

Cloud computing is the branch of technology that offers the users to utilize various computational, networking, storage, software and hardware resources on pay as you go basis. Several organizations are migrating to cloud as it is a cost-effective solution. This paper aims to solve the problem of resource leakage (memory, disk space, network channels, virtual cores, etc.) due to the generation of orphan VMs. The optimum usage of resources is often restricted due to the creation of orphan VMs. Hence, the demands of users are not fulfilled. This is an emerging problem in various cloud platforms such as OpenStack, VMWare, etc. The orphan VMs decreases the availability of resources and thus results in certain delays or deadlocks, interruption of service, degraded system performance, depletion of the pool of shared resources, etc. The objective of this paper is to overcome the problems caused by orphan VMs by implementing an appropriate solution for the end to end termination of VMs. To conduct the research, OpenStack cloud has taken into consideration.
