在本文内容中,以对网站群的构建方法和理论为研究对象,通过对网站群云计算应用平台的构建,对云计算在网站群架构和安全性设计中的具体应用进行阐述.通过具体研究,文中对网站群对云计算在其中的应用提出了两个方面,首先,就是基于IaaS模式来实现网站群中的云计算应用基础平台进行搭建,并通过SaaS模式来对网站群内容的管理云计算平台进行搭建;其次,就是利用已有的公共云和私有云环境,为网站群系统的安全性提供全面保障. 相似文献

随着信息化建设的不断深入,公众对高校网站服务水平要求提高,高校网站原有的一群模式架构已经不适合。中国科学技术大学采用网站群架构设计方法,对校内各个网站重新设计部署。围绕网站即服务这个宗旨,在网站群的构建过程中提出网站生态系统用户模型,并根据服务的映射关系提供管理上和软件技术上的服务,着重对校内各网站管理员进行与网站群内容管理平台配套的技术支持和环绕网站群平台的技术开发,提供高效内容搜索、RSS推送服务、访问量统计分析、WML页面发布、稿酬计费统计等功能。历时一年时间,成功对校内各个网站进行改版,构建了包含学校各党政机关部处、各院系科研教学机构和学校社团的网站群系统。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity. 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F. 相似文献

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities. 相似文献
