Openstack Cloud Performance Optimization using Linux Services

Cloud computing is an emerging trend for online computing and resource management. OpenStack is one of the most widely used open source platform for establishing public and private clouds. Besides its implementation issues much of the importance is being given on its performance optimization. This paper focuses on such a study to improve performance of an OpenStack Cloud and its further optimization by configuring the Linux services like rpcbind for Remote Procedure Calls (RPC). The benchmarking is done by executing multiple MapReduce benchmarks on a configured multi-node Hadoop cluster on the cloud as a software service. The results indicates that after configuring the rpcbind service in the cloud, the performance of its software services enhances by means of reduced elapsed time of the benchmarks executed.
