The performance of Computer system did not increase rapidly despite growing computing power. It depends on many other factors, but often it found rapidly degraded due to improper handling of resources like resource leakage, the flaw in programming, resource exhaustion or malicious attacks. These vulnerabilities became solemn when it affected hues number of users in the open-source cloud. This paper exhibits the degradations of virtual machines (VMs) availability in cloud-computing due to malicious attacks. Simulation result shows how orphaned VMs accumulate over time due to VM leakage and effected pool of resources. The paper describe some techniques applicable at multiple components of the cloud to identify and eliminate the orphaned VMs. Finally the experimental results show that how orphan control technique improved the availability of VMs even during various malicious attacks.
