چکیده مقاله :
Cloud data centers (CDCs) have witnessed significant growth to meet the increasing demands of modern applications. However, this expansion has raised concerns regarding the environmental impact, energy requirements, and electricity costs associated with data centers. The network infrastructure, serving as the communication backbone of these data centers, plays a crucial role in their scalability, performance, cost, and, most importantly, energy consumption. This review provides meaningful perspectives and valuable insights into the state-of-the-art research regarding the problem of virtual machine placement (VMP), focusing on the network-aware energy efficiency aspects of data centers. It provides an overview of VM placement and presents a comprehensive survey of prominent VM placement algorithms from the existing literature. Additionally, a thematic taxonomy of network-aware algorithms is introduced, highlighting the key energy consumption metrics and presenting a new classification of VMP algorithms that considers datacenter network (DCN) topology, traffic patterns, communication patterns, and energy reduction strategies. Besides addressing pertinent research questions in this domain, this review summarizes the findings and suggests potential avenues for future research, guiding researchers in designing and implementing more effective and efficient network-aware VM placement algorithms that optimize energy consumption, improve network performance, and minimize migration costs.
