Comparing energy-aware vs. cost-aware data replication strategy

Abstract

The sharp increase of the overall data amount makes their access and processing harder. Data replication is a well known technique that helps to decrease access time and improve reliability. In the context of Cloud Databases, most of data replication strategies do not answer simultaneously to performance and provider's profit with an awareness on energy consumption. In this paper, we compare different data replication strategies. Some of them intend to reduce the overall energy consumption when others intend to maximize the profit. We highlight that very few data replication strategies figure out simultaneously solutions for those issues even if there is a high demand from industries to reduce energy consumption and carbon footprint. We finally analyse why and how the race for profit and energy savings should be researched together.

Energy and Expenditure Aware Data Replication Strategy

“…However, we have supposed that storing data block the node from sleeping to keep access to the data it stores. This implies some differences compared to results in [23] in terms of energy consumption.…”

“…Authors in [23] state that there are very few strategies that consider both expenditure and energy consumption. Among those strategies, [24] aims to reduce energy consumption in order to maximize the provider profit.…”

“…This simulator has been extended by [6] in order to take into account data replication while considering heterogeneous network bandwidth, and monetary cost of resources. Then, it has been extended to estimate the energy consumption [23]. Finally, we added the capacity for all nodes to be turned into sleep mode based on [14] in order to reduce the energy consumption.…”

Quantitative Analysis and Performance Evaluation of Target-Oriented Replication Strategies in Cloud Computing

“…Reference [163] has mentioned some of the valuable future directions. Besides all enhancements, these cost-based replication strategies should be implemented in a real cloud environment [116,117].…”

Crucial File Selection Strategy (CFSS) for Enhanced Download Response Time in Cloud Replication Environments

“…Although different studies defined data replication in different ways, the gist and aims of data replications are the same as promising methods for ensuring data accessible in a heterogeneous system environment. Researchers are eagerly and proactively placed their efforts to establish an appropriate data replication strategy according to business goals to achieve optimal performance in cloud replication systems 10,1 . Explicitly, replication strategies are a broad umbrella with extensive technology in the cloud storage system, accelerating data access through efficient processing mechanisms and significantly improving various cloud replication performance metrics 12 .…”
