Cloud Datacenter Selection Using Service Broker Policies:A Survey

Amid the landscape of Cloud Computing(CC),the Cloud Datacenter(DC)stands as a conglomerate of physical servers,whose performance can be hindered by bottlenecks within the realm of proliferating CC services.A linchpin in CC’s performance,the Cloud Service Broker(CSB),orchestrates DC selection.Failure to adroitly route user requests with suitable DCs transforms the CSB into a bottleneck,endangering service quality.To tackle this,deploying an efficient CSB policy becomes imperative,optimizing DC selection to meet stringent Qualityof-Service(QoS)demands.Amidst numerous CSB policies,their implementation grapples with challenges like costs and availability.This article undertakes a holistic review of diverse CSB policies,concurrently surveying the predicaments confronted by current policies.The foremost objective is to pinpoint research gaps and remedies to invigorate future policy development.Additionally,it extensively clarifies various DC selection methodologies employed in CC,enriching practitioners and researchers alike.Employing synthetic analysis,the article systematically assesses and compares myriad DC selection techniques.These analytical insights equip decision-makers with a pragmatic framework to discern the apt technique for their needs.In summation,this discourse resoundingly underscores the paramount importance of adept CSB policies in DC selection,highlighting the imperative role of efficient CSB policies in optimizing CC performance.By emphasizing the significance of these policies and their modeling implications,the article contributes to both the general modeling discourse and its practical applications in the CC domain.

Dynamic resource management using bandwidth brokers

The admission control issue in the design of a centralized bandwidth broker model for dynamic control and management of QoS provisioning is studied. A two-phase differentiated flow treatment based dynamic admission control scheme under the centralized bandwidth broker model is proposed. In the proposed scheme, the flow requests are classified into two classes and get differentiated treatment according to their QoS demands. We demonstrate that this admission control scheme can not only improve the resource utilization but also guarantee the flows＇ QoS. Furthermore, the admission control is divided into two phases： edge admission control and interior admission control. During the interior phase, the PoQ scheme is adopted, which enhances the call processing capability of the bandwidth broker. The simulation results show that the proposed scheme can result in lower flow blocking probability and higher resource utilization. And it also reduces the number of QoS state accesses/updates, thereby increasing the overall call processing capability of the bandwidth broker.

Morality should be taught as a compulsory course in higher education

From the tragedy of campus shooting in United States to animal tortures of Chinese college student,the morality and the effect it can have on the young people is arresting all the time.There are several aims which participants in the higher educational process.They may demonstrate as the aims about which they are concerned.Such aims,sometimes,may be referred to not as they were particular aims in the educational process but the proper aims of higher education itself.The aims of higher education may vary.It may be claimed that the aim of higher education is to develop the potential of all individuals or to education is to develop the potential of all individuals or to educate the whole man.So how do we understand the education of the"whole man"?It is obviously a phrase which can easily catch eyeballs.I think that it includes the concept which various aspects of human nature must be cultivated for,intellectual and imaginative,rational and emotional,or as it sometimes expressed,physical,mental,moral and spiritual.Someone argues that morality plays an important role in shaping lives and values of children,but not adults.In this paper,the author will discuss whether morality should be taught in college.

道德与morality之关系辨正

现代伦理学的重要主题是探讨道德的语言用法与规范性蕴含,尤其是在现代中国哲学与中国伦理学中,流行以道德观念为核心来诠释儒家思想。需要注意的是,以汉语词"道德"翻译西文moral或morality存在观念上的龃龉之处。Morality意指一个人的行为的正当性与规范性,若以中文术语译之,更恰当的对应是儒家之谓伦常、义或谓道义。汉语"道德"的意涵比伦常或者义要广泛,道德本于天道而成就于人道。先秦诸子皆称道德,儒家以仁义充实之,故后世以仁义道德连用。仁义道德与morality的一致性在于其为行为规范的内涵与价值,但仁义道德尤指君子已经表现出来的品质、能力及其教化百姓、泽被众生的功德,而morality则强调个体意志的自由、自觉选择所产生的行为规范性,含义相对较窄。以道德对译morality,并反过来用作为译名的"道德"来诠释中国哲学与中国伦理学,可谓是中国传统基于现代处境自我调适所产生的反向格义。

The Adventures of Huckleberry Finn is honored as the most typical novel of American literature after the Civil War. This story unveils the hypocrisy of religion and scoffs at the conventional social principle. Affected by the deep-rooted racial discrimination, Huck pays little respect to the black slaves as other white people do at first.

He never stops struggling inside, and eventually Jim's kindness and loyalty helps Huck to waken humanity in his heart and defeat his moral conflict.

The Eclipsed Symbiosis of Aesthetics and Morality in The Benefactor

This essay expounds the indiscernible symbiosis that hitches formalist aesthetics to moral consciousness via an analysis of the fictionality of metafiction,the uncertainty of dream narrative,and Sontag’s sarcasm of anti-intellectual behaviors imbedded in her novel The Benefactor.The fictive nature of the novel is well manifested via the pervasive disclosure of self referential narration made by Hippolyte.The glaring discrepancies between the dreamlike life experiences expatiated on by Hippolyte in the main body of the novel and the circumstances laid plain en masse in his journals,letter,and manuscript which come out at the close of the novel are a strikingly acute revelation to remind a reader of the novel of the uncertainty of Hippolyte’s narration.The concluding section of the essay is an analysis of Sontag’s satirical version of anti-intellectualism:She arranges for the two abnormal characters—one is fond of daydreaming,and the other is temperamentally“camp”—to revert to the normal way of life and become intellectually pedestrian.The conclusion of the novel obscurely implies that the realities of the world have rendered it difficult for such a moral disburdenment as is set forth in Sontag’s aesthetic conceptualization to come into being.
