云计算技术在网站群安全架构中的应用研究

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.     

网站群在高校网站建设和安全管理中的应用

为了解决目前高校网站由于采用不同技术进行分散建设带来的管理维护和网站安全等问题,在深入研究网站群内容管理平台的基础上,对学校网站群系统进行了规划、设计和部署.系统采用内网和外网相分离的3层架构,可以保护Web服务器不被暴露到网络上,提高了网站的安全性.实践表明,网站群系统能够有效解决学校网站建设中存在的技术和管理问题,是一种高效、安全的解决方案.     

基于开放平台的高等教育私有云研究

云计算是能够在任何时间任何地点为各种服务环境交付用户计算需求的解决方案,文章依托云计算的基础理论和虚拟化解耦技术,提出高等教育私有云系统的完整建设方案。从教育私有云的软硬件体系、应用软件架构、实际应用场景以及相关高级特性和管理因素等方面详细阐述其设计思想和应用架构。该私有云的实施构建必将极大地改善高校信息化的建设和管理模式,推动教育信息化的快速发展。     

基于云计算的政府网站群建设策略研究

随着信息社会的发展,各级政府部门对政府网站的建设日益重视,政府网站群成为社会公众获取政府各项服务的重要渠道。介绍了政府网站群及云计算的基本概念,分析了当前政府网站群运维存在的主要问题,提出了基于云计算建设政府网站群的策略措施。     

网站信息监测系统的设计与实现

随着高校网站群的广泛应用，网络信息量巨增且管理复杂.如何快速获取网站最新发布内容、确保网站的安全性与准确性已成为网站管理人员亟待解决的问题.基于Python语言开发的网站信息监测系统，实现了监测网站最新发布消息、统计历史新闻、绘制新闻数量折线图、查看网站的在线状态、监测机房环境温湿度变化以及监测网络设备连接状态等功能，对推进高校信息化建设与管理工作具有一定的积极作用.     

高校网站建设安全问题分析与对策

分析高校网站建设的现状及存在的安全问题,提出建立专业的网站管理员队伍、健全管理制度、统一站群平台和部署内外分离的网站群系统架构等措施,确保高校网站安全、稳定运行。     

建设适用于高校的云平台

云计算是互联网技术的发展趋势,教育领域的云计算环境的建设是教育信息化的热点。文章提出在教育领域云计算平台的基本架构,重点探讨我国高校立足于云计算的网络教学平台建设的适用选择和实现路径,探索如何利用云计算技术建立新型的网络教学平台。     

新形势下高校网站群建设与服务管理探究——以北京大学为例

高校网站是对外宣传与交流的重要窗口,各级部门及院系均有网站建设的需要,因此网站群成为许多高校网站建设与管理的选择方案。随着信息化技术的快速发展,高校网站集群规模不断扩大以及功能日趋多元化,高校网站群在内容管理、安全防护等方面面临新的挑战。该文以北京大学为例,提出并设计建设了新一代网站集群系统,进一步深化集群的概念,使信息资源整合得更加深入、管理使用更加灵活、安全体系更加健全,有效促进了高校的信息化建设。     

高校网站群及其外延服务研究

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。     

中外高校就业类网站现状与分析——基于五所高校的对比研究

信息化就业指导平台已经成为推动大学生就业的重要途径,高校就业网站是信息化平台的重要组成部分。但高校就业网站多数存在学生利用率低、信息更新慢、交互性差、缺乏专业运营人员等问题。本文从功能设计及使用的角度对中外五个大学生就业网站在网站设计、用户体验、互动设计、信息架构、资源整合等方面做了系统的对比分析,并提出了高校就业网站相应的改进策略。

漏洞百出的教育

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?     

Western and Eastern culture differences in commercial field

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.     

只要努力,不要后悔

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.     

浅谈移民问题

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.

团图为数的图中的闭团贯数

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.     

Sister Carrie, an Adherent of Desires

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.
