Efficient Resource Management in Cloud Computing

摘要

Cloud computing, one of the widely used technology to provide cloud services for users who are charged for receiving services. In the aspect of a maximum number of resources, evaluating the performance of Cloud resource management policies are difficult to optimize efficiently. There are different simulation toolkits available for simulation and modelling the Cloud computing environment like GridSim CloudAnalyst, CloudSim, GreenCloud, CloudAuction etc. In proposed Efficient Resource Management in Cloud Computing (EFRE) model, CloudSim is used as a simulation toolkit that allows simulation of DataCenter in Cloud computing system. The CloudSim toolkit also supports the creation of multiple virtual machines (VMs) on a node of a DataCenter where cloudlets (user requests) are assigned to virtual machines by scheduling policies. This paper represents, allocation policies, Time-Shared and Space-Shared are used for scheduling the cloudlets and compared with the constraints (metrics) like total execution time, a number of resources and resource allocation algorithm. CloudSim has been used for simulations and the result of simulation demonstrate that Resource Management is effective.
