Cloud computing using OCRP and virtual machines for dynamic allocation of resources

Abstract

Cloud computing is the most integral part in today's world of computing because it reduces the complexity and cost of applications making it reliable and economical. Cloud computing provide three service models namely, Platform as a Service (PaaS), Software as a Service (SaaS) and Infrastructure as a Service (IaaS). The proposed system uses the IaaS service which provides users storage as a service. The system follows the Optimal Cloud Cost Resource Provisioning (OCRP) algorithm to calculate the optimal cost and allocate virtual machines to the user. This algorithm provides a logic that manipulates the virtual machines so that none are overloaded at a given instance of time. The resources are monitored dynamically on the server screen and in an indexed format stored in the virtual machines provided by the cloud server. This system is built on the Ubuntu 12.04 LTS server and the OpenStack cloud server is built on a Metal as a Service (MaaS) server which is hosted on a hard disk. As the MaaS server is stored on a hard disk, the resources becomes 24/7 accessible to the provider. This reduces resource loss and also provides a backup to the system.
