Robust optimization for energy-efficient virtual machine consolidation in modern datacenters

Robayet Nasim, Enrica Zola, Andreas J. Kassler
2018 Cluster Computing  
A more risky operator may well choose a more opportunistic schedule leading to lower energy consumption but also higher risk of SLA violation.  ...  We also show that setting aside additional resource to cope with uncertainty of workload influences the overbooking ration of the servers and the energy consumption.  ...  The relative expected power for the multi uncertainty case is more than 1 when both the uncertain parameters have maximum uncertainty.  ...

Cost and Performance Optimization for Cloud-Based Web Applications Deployment [article]

Seyedehmehrnaz Mireslami, University Of Calgary, University Of Calgary, Behrouz H. Far, Mea Wang
2018
In the next stage, a multi-cloud datacenters cost optimization algorithm is proposed to distribute the cloud resources in different cloud datacenters to improve the web application availability and maintain  ...  Furthermore, due to lack of understanding of the pricing model and the cloud IaaS, a customer may pay more than necessary or may not fully utilize the purchased resources.  ...  Therefore, it eliminates the relatively more expensive inter-datacenter and external datacenter communication costs leading to solutions with slightly lower total deployment costs.  ...
