Efficient Resource Utilization Algorithm (ERUA) for Service Request Scheduling in Cloud
N. Ramkumar, Nivethitha Somu · 2013
Cloud computing provides us 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. Our 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. Performance analysis made with the existing scheduling techniques shows that our algorithm gives out a more optimized schedule and enhances the efficiency rate. I INTRODUCTION Cloud computing an emerging and an enabling technology which made us to think beyond what is possible. Realizing the services and amenities provided by the cloud many organizations decided to jump into cloud in order to reduce the infrastructure cost and energy consumption. Cloud makes them to move their business with different range and style of services. It had the changed the traditional way of using the resource infrastructure. Service request scheduling is the most crucial area with respect to the profit of the service provider and the QoS of the user.
