VM consolidation: A real case based on OpenStack Cloud [PDF]

Future Generation Computer Systems, 2014
In recent years, Cloud computing has been emerging as the next big revolution in both computer networks and Web provisioning. Because of raised expectations, several vendors, such as Amazon and IBM, started designing, developing, and deploying Cloud solutions to optimize the usage of their own data centers, and some open-source solutions are also ...

A thermal‐aware VM consolidation mechanism with outage avoidance

Software: Practice and Experience, 2019
SummaryEfficient energy and temperature management techniques are essential elements for operators of cloud data centers. Dynamic virtual machine (VM) consolidation using live migration techniques presents a great opportunity for cloud service providers to adaptively reduce energy consumption and optimize their resource utilization.

Stochastic VM Multiplexing for Datacenter Consolidation

2012 IEEE Ninth International Conference on Services Computing, 2012
Virtual machine (VM) placement for Datacenter (DC) consolidation is a challenging problem, particularly in the face of VM workload fluctuation. In this paper, we present a stochastic model for optimization of DC consolidation and propose intelligent strategies for statistical VM multiplexing on physical machines (PMs) to ensure optimal use of hardware ...

Efficient VM Selection Heuristics for Dynamic VM Consolidation in Cloud Datacenters

2018 IEEE Intl Conf on Parallel & Distributed Processing with Applications, Ubiquitous Computing & Communications, Big Data & Cloud Computing, Social Computing & Networking, Sustainable Computing & Communications (ISPA/IUCC/BDCloud/SocialCom/SustainCom), 2018
Dynamic Consolidation of Virtual Machines (VMs) in a cloud data center requires live migration of VMs from over-utilized hosts. A primary but relatively an ignored part of consolidation process is the efficient selection of Virtual Machines from an over-utilized host for migration. Two VM selection policies, Threshold Based Selection (TBS) and Capacity

A survey on energy aware VM consolidation strategies

Sustainable Computing: Informatics and Systems, 2019
Abstract The rapid growth of Cloud computing is accompanied by a significant increase in the consumed energy by data centers. This huge increase in energy consumption has become a major concern because of both its costs and environment impact. Consolidating virtual machines (VMs) in minimum numbers of physical machines (PMs) is an effective way to ...
