Scheduling Resources in Cloud using Threshold Values at Host and Data Center level

Abstract — Cloud computing provides online resources of computing services as per demand of their client. One of the challenging areas in cloud computing is scheduling the computing resources among the client’s applications and services. If resource requirement of the cloud applications increase and host machine become overloaded then using migration techniques, cloud system need to transfer some of the virtual machines to another host machine, whose load is low. When cloud applications change their demand very frequently then the frequency of virtual machine migration will be high and our throughput will be low. This paper is proposing a threshold based approach to make efficient resource scheduling with minimizing number of virtual machine migration situation using compare and balance algorithm. The new, simple, flexible and dynamic threshold based resource scheduling algorithm get higher resource utilization with improved throughput for dynamic application as shown by the simulation results using the cloudsim simulato
