“…Furthermore, according to recent research, data centers are a huge and rapidly rising energy-consumption sector of the economy, as well as a substantial source of CO 2 emissions. Also, the research done by [92] the use of blockchain technology and cloud solutions facilitates and improves not only the aggregation of data and secured access to it, but also has a huge impact on the reduction of CO2 emissions and reduces the carbon footprint. Hence, reducing greenhouse gas (GHG) emissions is an important energy policy objective for many nations, as well as achieving the United Nations Sustainable Development Goal (SDG) to transform the world by 2030.…”

Data centers are becoming considerably more significant and energy-intensive due to the exponential growth of cloud computing. Cloud computing allows people to access computer resources on demand. It provides amenities on the pay-as-you-go basis across the data center locations spread over the world. Consequently, cloud data centers consume a lot of electricity and leave a proportional carbon impact on the environment. There is a need to investigate efficient energy-saving approaches to reduce the massive energy usage in cloud servers. This review paper focuses on identifying the research done in the field of energy consumption (EC) using different techniques of machine learning, heuristics, metaheuristics, and statistical methods. Host CPU utilization prediction, underload/overload detection, virtual machine selection, migration, and placement have been performed to manage the resources and achieve efficient energy utilization. In this review, energy savings achieved by different techniques are compared. Many researchers have tried various methods to reduce energy usage and service level agreement violations (SLAV) in cloud data centers. By using the heuristic approach, researchers have saved 5.4% to 90% of energy with their proposed methods compared with the existing methods. Similarly, the metaheuristic approaches reduce energy consumption from 7.68% to 97%, the machine learning methods from 1.6% to 88.5%, and the statistical methods from 5.4% to 84% when compared to the benchmark approaches for a variety of settings and parameters. So, making energy use more efficient could cut down the air pollution, greenhouse gas (GHG) emissions, and even the amount of water needed to make power. The overall outcome of this review work is to understand different methods used by researchers to save energy in cloud data centers.

With the continuous development of finance, the financial department is gradually transformed from an efficient department to an inefficient one with high power. Blockchain technology is decentralized and data cannot be modified, which caters to the demand of financial sharing services and promotes the rapid professional application of blockchain technology. This paper introduces the financial sharing service system driven by information technology. This system further optimizes yonyou NC financial and supply chain system, and configura ORACLE Hypolon total Budget management system, Micro-ecologyoa and financial sharing service system. The built-in intelligent information processing model includes two: first, block SHA256 verification, mathematical model reference formula (1); Second, the new block to obtain accounting rights, mathematical model reference formula (2). The basic operation principle of financial shared service digital system based on block chain technology is to use formula (1) to SHA256 check the new block information; Then formula (2) is used to obtain new accounting rights for all new blocks that have passed verification. This paper studies the assessment design of digital financial sharing service system based on block chain technology, focuses on the principle of block chain technology, and expounds the relevant content of assessment design of digital financial sharing service system. In the data test, refer to Table 1 and Fig. 2 in Part 4 of the paper. The assessment design of digital financial sharing service system based on blockchain technology has a more efficient performance in the assessment design of digital financial sharing service system.

“…Blockchain is a distributed ledger technology that aids decentralized, distributed computing in a trustless environment. Blockchain has witnessed adoption across diverse domains including finance, e-voting [12], and public sector [13]. The attention attracted by blockchain is primarily due to its most popular application, i.e., Bitcoin [14], which effectively seeks to conduct financial transactions in a peerto-peer manner without the support of the conventional banking system.…”

Blockchain-enabled real-time SLA monitoring for cloud-hosted services

et al. 2021

View full text Add to dashboard Cite

Cloud computing is an important technology for businesses and individual users to obtain computing resources over the Internet on-demand and flexibly. Although cloud computing has been adopted across diverse applications, the owners of time-and-performance critical applications require cloud service providers’ guarantees about their services, such as availability and response times. Service Level Agreements (SLAs) are a mechanism to communicate and enforce such guarantees typically represented as service level objectives (SLOs), and financial penalties are imposed on SLO violations. Due to delays and inaccuracies caused by manual processing, an automatic method to periodically verify SLA terms in a transparent and trustworthy manner is fundamental to effective SLA monitoring, leading to the acceptance and credibility of such service to the customers of cloud services. This paper presents a blockchain-based distributed infrastructure that leverages fundamental blockchain properties to achieve immutable and trustworthy SLA monitoring within cloud services. The paper carries out an in-depth empirical investigation for the scalability of the proposed system in order to address the challenge of transparently enforcing real-time monitoring of cloud-hosted services leveraging blockchain technology. This will enable all the stakeholders to enforce accurate execution of SLA without any imprecisions and delays by maintaining an immutable ledger publicly across blockchain network. The experimentation takes into consideration several attributes of blockchain which are critical in achieving optimum performance. The paper also investigates key characteristics of these factors and their impact to the behaviour of the system for further scaling it up under various cases for increased service utilization.
