An Integrated Review on Resource Management, Scheduling, and Energy Efficiency in Cloud Computing
Main Article Content
Abstract
Cloud computing offers a flexible and on-demand
access of computing resources and therefore resource
management is a key issue of maintaining high performance, cost
effectiveness, and sustainability. This paper will give an overview
of the main issues of cloud resource management such as the
resource allocation strategies, scheduling methods, and the green
(energy efficient) practices of cloud computing. It addresses the
problem of resource contention, over- and under-provisioning,
fragmentation, and dynamism of workload variation, and their
effect on Quality of Service (QoS) and Service Level Agreements
(SLAs). The paper also looks at the case of the static, dynamic and
QoS-driven scheduling which are designed to provide a balance
between the needs of the users and the objectives of the provider
and the ability to provide equitable and optimal resource
utilization. Besides, energy efficiency is examined using the
concept of the use of static and dynamic power control,
virtualization, and green cloud to lower the cost of operation and
environmental effects.
