A Comprehensive Review on Autonomous Consolidation of Virtual Machine for Energy and Resource Management
Gaurav Bajpai, Pawan Singh, Abhay Kumar Agarwal · 2023
Energy efficiency and awareness of power utilization are significant challenges while building up a cloud computing infrastructure and next-generation data centers. Consolidating Virtual Machines (VMs) is frequently used to lessen data centers’ negative impact on the environment and their utility bills. When idle or underused hosts enter sleep mode, it is essential to consider workload variations and energy-efficient and optimized resource utilization. Excessive load on an individual server decreases the Quality of Service (QoS). VM consolidation is supported by the procedures of placing and migrating virtual machines. Problems with variability and scalability of hardware facilities, load volatility, and migration complexity all contribute to the difficulty of the VM consolidation process. This study provides an in-depth look at the strategies and problems of virtual machine consolidation in terms of energy efficiency, resource allocation, migration, and placement schemes. This study proposes the reduction of carbon emissions, which directly-indirectly saves the environment.
