Cloud computing provides the user with the massive pool of resources in terms of pay-as-you-use policy. Cloud delivers these resources on demand through the use of network resources under different load conditions. As the users will be charged based on their usage the effective utilization of resources poses a major challenge. To accomplish this, a service request scheduling algorithm which reduces the waiting time of the task in the scheduler and maximizes the Quality of Service (QoS) is needed. The authors' proposed algorithm named Effective Resource Utilization Algorithm (ERUA) is based on 3-tier cloud architecture (Consumer, Service Provider and the Resource Provider) which benefits both the user (QoS) and the service provider (Cost) through effective schedule reallocation based on utilization ratio leading to better resource utilization.
