cloud computing1. introductioncloud computing is known as the most anticipated technological revolution over the entire world, and the reason why cloud computing has brought widespread attention is that it not only represent a new technology appeared, but also lead to the entire industry to change. therefore, the ranking of national competitiveness will change accordingly.2. cloud computing definition and applicationthe concept of cloud computing is put forward by google, which is a beautiful network applications mode. based on increasing in internet-related services and delivery models, it provides dynamic, easy to expand and virtualized resources usually through the internet. this service can be related to it, software and internet; other services can be supported too. it means that computing power can be circulation as a commodity. as we expect, more and more enterprise use this new technology into the practical application, such as webmail, gmail and apple store use it for computing and storage. with the technology development, cloud computing has given full play to it roles, industry, newcomers and media buy computer technology to make network cheaper, faster, convenient and better control. cloud computing is used in the distributed computers by computing, rather than the local computer or remote server, the operation of the enterprise data center and the internet are more similar. this process allows companies to be able to switch resources to the urgent application according to computer and storage systems demand access. this means that the computing power can be negotiable, like water and electricity, access convenient and low-cost. the biggest difference is that it is transmitted via the internet.3. advantageby providing a large and secure data storage centers for cloud computing, users do not have to worry about their own data which be lost for some reason or destroyed by computer virus invasion, such as some data stored in the hard disk data will be lost by the computer damaged and virus invasion, so that users cannot access the data and recover data, another disadvantage may also appear when other people use your computer steal the users computer, such as personal confidential information and business data loss. “gate of blue photos is a typical insecure example. if user uploads the photos through the interne into data storage center, it may have less chance to access personal confidential information. and with cloud computing development, for the user, these services are free of charge, for the future, advanced technology will certainly become a cash cow for merchants, and for the country, the computing power is also able to reflect a country technological level and the level of overall national strength.as the user data stored in the cloud storage center, can reduce customer demand for the hardware level, coupled with cloud computing extremely powerful computing capability, it can enable users to call data more convenient and quick if can add the high-speed networks. users no longer need replace the computer caused by having no enough hard disk space and cpu computing power. otherwise, users only surf the internet to access cloud storage center and then easily access the data.as powerful data storage centers, the most wonderful features is sharing data. no matter computer data or a variety of communication devices such as mobile phones and pda. when some damaged appeared in your phone, lost or replaced in order to chase the trend of the times and phone, data copy is a tedious thing. however, in another way, you can solve the entire problem through cloud storage center. cloud computing services will create more millions of jobs. on march 6, a news show that show that microsoft statement a commissioned research conducted by the world-renowned market analyst firm idc. the research show that cloud computing will create nearly 14 million new jobs worldwide in 2015. and also predicted that it can stimulate it innovation and brought the new revenue which can reach about $ 1.1 trillion, coupled with cloud computing efficiency substantially promote, the organization will increase re-investment and work opportunity. idc chief research officer , as senior vice president, john f. gantz said: for most organizations, there is no doubt that cloud computing will significantly enhance the return on investment and flexibility, reduce investment costs, and bring revenue growth multiplied as well, we usually believe that cloud computing will reduce jobs by mistake, the opposite, it can create a lot of jobs around the world, no matter emerging market, small cities and small businesses will increase employment opportunities and get benefit from cloud computing. reference1 4. disadvantagewith large storage center, cloud computing strongly urges powerful hardware conditions and safety measures, which including a large storage space and powerful computing capabilities. as todays scientific and technological rapid develop, user increased, hardware capabilities become one of the necessary condition for development, moreover, the cloud should be kept to enhance their computing power and storage space, and endless. security measures also include two aspects; firstly, it is necessary to ensure that user data not damaged, lost, and stolen by others, which requires a strong it team to full range of maintenance and strict access management strategies. some information has been confirmed, the existing cloud computing service provider still cannot guarantee no similar problem occurs. for users, this is a very serious problem. another security issue is a natural or unnatural disaster, also can cause the storage center damaged, can cause users cannot access.cloud computing services are available via the internet, therefore, user usually have high demands for network access speed, although domestic access speeds improve fast, but compared with lan, it will appear delays, incomparable, in addition, no network, the user will not be able to access cloud services.the rapid rise of cloud technology, in another perspective, also restricts the speed of development, which also lead to lower demand for high-end devices. it is the basic reason why can restrict terminal development. customer needs, determine the business requirements for products, if customers reduce the terminals hardware and software requirements, the business will be greatly reduced the degree of product development and restricted the pace of the terminal technology development.5. cloud computing development in chinain china, cloud computing services have been in a state of rapid development. looking at the cloud computing industry, government accounted for a major position, and in the market they have also been given the affirmation of the cloud computing. the cloud computing services major support for government agencies and enterprises, therefore, the personal cloud computing services in china is a potential big cake and wait for people enjoying. however because of the domestic personal network speed upgrade too slow, and relevant government network supervision, the development of personal cloud computing services will have more difficult. due to excessive speculation in the international aspects, in our country, a lot of companies want to get some benefit from the rapid development of technology, exploit cloud computing services projects and promote enterprise development. my personal view is that enterprises should do some preparation, judge its good or bad and prospects, as well as estimate the strength of the company and do their best. through access to information discovery, cloud computing as a technology trend has been got the worlds attention, but look at the forefront of foreign enterprise closely, we can easily find almost no companies start the business rely on cloud computing; cloud computing applications and related research are also mostly implement by those large enterprise with more funds. as the prospects for development, for the enterprise, profit is the most critical issues.although cloud computing has been integrated into our lives, but the domestic development of cloud computing is still confronted with many problems, such as lack of user awareness, migration risk, lack of standards, user locks, security and data privacy, safety, standards, data privacy has become a topic of which we are most concerned. nowadays, people still lack of comprehensive, systematic cognitive of cloud computing, part of them just imitate completely others and foreign experience, ignoring the specific conditions in our country, resulting in spending much money, but failed to alleviate the complex it issues. in the original data center, hardware is relatively independent, but migrates to cloud computing data center, systematic assessment and scientific analysis must be essential. otherwise it may lead to the hardware platform not achieve the proper effect and even the collapse of the application system. cloud computing products is quite diversity, but the birth of the cloud standard is extremely difficult, the major manufacturers just have their own standards, the government is also involved, both of them are striving to be able to dominate the major position, so more efforts are still needed. the other faced challenge is how to provide users legitimate services is also very important, except the risks in the systems. compared with traditional data centers, it cloud provided more services diversity, which also bring more difficult to control. therefore, analyze the needs of users, reasonable, enforceable service level agreements (slas) provided will help users establish confidence in cloud computing services in a large extent. security problems can be said that a key factor in cloud computing landing. amazon failure made people deep in thought, which is just one factor of the security. the other security risks include user privacy protection, data sovereignty, disaster recovery, and even illegal interests caused by some hackers. in the era of cloud computing, there will be more user privacy data placed in the clouds, more data, and more value. most importantly, lack of users trust will lead to cloud computing landing.although the development road is very far away, but the government has been giving support and encouragement. in 2012 cloud computing industry development forum was successfully held, which is strong evidence. at the meeting, as a ccid consulting, cloud industry observers, as well as excellence forerunner of the cloud computing industry, microsoft, with their co-operation, complete the first china cloud economic development report”, which shows that in-depth interpretation the content of cloud formation and specify the key factor of economic development in the cloud. the result obtained based on the long-term observation and in-depth research on cloud computing industry. in addition, the participants share their own point about industry environment, market situation, technology development, application service elements and so on; they also can come up with any question about the cloud computing, expects will do their best to give analysis and authoritative view. reference26. future prospectsabout cloud computing services future prospects, in my opinion, it will have great potential, we can find out the answer from the action of the giants of the major it companies, but now it still in a state of excessive speculation. many small companies have no any knowledge and experience about it, and still want to exploit the services project. i dont think it is a sagacious decision. in fact, for current state, i maintained a cautious attitude, as a corporate without strong financial strength, i think they should focus on business development and growth, in order to reduce unnecessary waste of resources, they can develop and use it when the technology get mature stage.finally, have to say that the future of the cloud computing, it not only can provide unlimited possibilities for storage, read, and manage data using the network. but also provides us infinite computing power because of its huge storage space, there is no powerful computing capabilities, it cannot provide users with easy and fast. in one word, the development potential of cloud computing is endless.7. reference 1 microsoft news, cloud computing services will create more millions of jobs.2012-03-062 ccidnet news, cloud computing industry development forum was successfully. 2012-03-07下面资料为赠送的地产广告语不需要的下载后可以编辑删除就可以，谢谢选择，祝您工作顺利，生活愉快！地产广告语1、让世界向往的故乡2、某沿河楼盘：生活，在水岸停泊3、一江春水一种人生4、某钱塘江边楼盘：面对潮流 经典依旧5、海景房：站在家里，海是美景；站在海上，家是美景6、以山水为卖点的楼盘：山水是真正的不动产7、某城区的山腰上的楼盘：凌驾尊贵 俯瞰繁华8、某地势较高的楼盘：高人，只住有高度的房子9、某学区房：不要让孩子输在起跑线上10、尾盘：最后，最珍贵11、回家就是度假的生活12、生命就该浪费在美好的事情上我们造城2、我的工作就是享受生活3、 我家的客厅，就是我的生活名片4、在自己的阳台 看上海的未来5、公园不在我家里 我家住在公园里6、这里的花园没有四季7、*，装饰城市的风景8、*，我把天空搬回家9、房在林中，人在树下10、生活，就是居住在别人的爱慕里11、到星河湾看看好房子的标准12、好生活在珠江13、爱家的男人住百合城市岸泊： 城市的岸泊，生活的小镇生活之美不缺少，在于发现情趣不在于奢华，在于精彩生活有了美感才值得思考玫瑰庄园： 山地生态，健康人生卓越地段，超大社区一种完整且完善的环境，像原生一样和谐原生景象 自然天成人本理念 精品建筑知名物业 智能安防诚信为本 实力铸造比华利山庄：海岸生活引领世界的生活方式海岸生活22公里的奢华海岸生活高尚人生的序曲海岸生活人与自然的融合苹果二十二院街：人文 自然 现代铺的蔓伸荣和山水美地：让世界向往的故乡香港时代： 时代精英 开拓未来领衔建筑，彰显尊贵绿地崴廉公寓：金桥 40万平方米德国音乐艺术生活汇都国际： 昆明都心，城市引擎财富之都 风情之都 梦幻之都 文化之都 商贸之都西部首座巨型商业之城颠峰商圈的原动力，缔造西部财富新领地新江湾城： 绿色生态港 国际智慧城新江湾城，一座承载上海新梦想的城区上海城投，全心以赴建设知识型，生态型花园城区风和日丽： 入住准现楼，升值在望湾区大户，空中花园大格局下的西海岸市中心： 市中心 少数人的专属颠峰珍贵市中心的稀世名宅正中心 城市颠峰领地颠峰 勾勒稀世名宅繁华 不落幕的居家风景地利 皇者尽得先机稀世经典180席阳光国际公寓：阳光金桥来自纽约的生活蓝本钟宅湾： 海峡西岸生态人居 休闲商务区汇聚国际财富与人居梦想的绝版宝地二十一世纪是城市的世纪，二十一世纪也是海洋的世纪谁控制了海洋，谁就控制了一切站在蓝色海岸的前沿，开启一个新的地产时代东南门户 海湾之心海峡西岸生态人居 休闲商务区让所有财富的目光聚集钟宅湾，这里每一天都在创造历史上海a座（科维大厦）：创富人生的黄金眼掘金上海！创富人生！远东大厦： 花小公司的钱，做大公司的事未来城： 无可挑战的优势 无可限量的空间绿地集团： 居住问题的答疑者，舒适生活的提案人茶马驿栈： 精明置业时机 享受附加值 财富最大化雪山下的世外桃源 茶马古道上千年清泉之乡金地格林春岸：城市精英的梦想家园繁华与宁静共存，阔绰身份不显自露建筑覆盖率仅20%，令视野更为广阔占据最佳景观位置，用高度提炼生活完美演绎自然精髓，谱写古城新篇章创新房型推陈出新，阔气空间彰显不凡365天的贴身护卫，阔度管理以您为尊金地格林小城：心没有界限，身没有界限春光永驻童话之城我的家，我的天下东渡国际： 梦想建筑，建筑梦想齐鲁置业： 传承经典，创新生活比天空更宽广的是人的思想创新 远见 生活嘉德 中央公园：一群绝不妥协的居住理想家 完成一座改变你对住宅想象的超越作品极至的资源整合 丰富住家的生活内涵苛求的建造细节 提升住家的生活品质地段优势，就是永恒价值优势设计优势，就是生活质量优势景观优势，就是生命健康优势管理优势，就是生活品味优势空中华尔兹： 自然而来的气质，华尔兹的生活等级享受，没有不可逾越的极限所谓完美的习惯，是舒适空间的心情定格！临江花园： 经典生活品质风景中的舞台美林别墅： 源欧美经典 纯自然空间住原味别墅 赏园林艺术淡雅 怡景 温馨 自然钱江时代： 核心时代，核心生活核心位置 创意空间 优雅规划 人文景观 财富未来城市精神，自然风景，渗透私人空间泰达时尚广场： 是球场更是剧场城市经济活力源时尚天津 水舞中国未来都会休闲之居创意时尚 天天嘉年华健康快乐新境界商旅新天地 缔造好生意城市运营战略联盟，参与协作，多方共赢华龙碧水豪园： 浪漫一次，相守一生东方莱茵： 品鉴品位 宜家宜人建筑一道贵族色彩品鉴一方美学空间品位一份怡然自得荡漾一股生命活力坐拥一处旺地静宅体会一种尊崇感受常青花园（新康苑）：新康苑 生活感受凌驾常规大非凡生活领域 成功人士的生活礼遇拥有与自己身份地位相等的花园社区在属于自己的宴会餐厅里会宾邀朋只与自己品味爱好相同的成功人士为邻孩子的起步就与优越同步酒店式物管礼遇拥有一屋两公园 前后是氧吧的美极环境水木清华： 住在你心里福星惠誉（金色华府）：金色华府，市府街 才智名门释放生命的金色魅力真正了解一个人，要看他的朋友，看他的对手。真正了解一种生活，也当如此。核心地段（区位是一面镜子，照见家的质素）隐逸空间（环境是一面镜子，照见家的质素）超大规模（点亮与过往不同的“大”生活）成熟配套（周边一切是镜子，照见家的质素）精品建筑（外揽天下，内宜室家）均好户型（每天每秒都被释放到四壁之外）大唐新都： 原创生活，非常空间住宅不是炫耀的标签，生活是用来享受的。人信.千年美丽： 森庭画意.千年美丽宁静是一种内在的力量生活是与自然的恋爱在自然中体验自由的生存建筑让人迷恋的核心是思想华智.翡翠星空： 创意生活由此进时代美博城： 繁华领地 时尚生活浪漫无极限阳光海岸： 美景与生活的邂逅带着些许闲散情绪，安享私藏一片湖的幸福梦幻湖畔 温柔横亘在回归前方 这是你的见.心的家景江华庭： 静享都市繁华 新锐生活核心海虹.景： 城市在变 世界观也要变海虹.景 国际社区一个改变你世界观的城市文化住宅海虹.景 区位世界观一块好地 不仅要放到空间中 更要放到时间中去评价海虹.景 美景世界观先成为园林鉴赏家才能鉴赏城市海虹.景 享受世界观放手生活是享受的开始海虹.景 生活世界观洞悉时尚潮流才能洞悉生活的变化海虹.景 空间世界观空间随意识而变 空间是流动变化的碧水晴天： 生活就是寻开心驾奴.桥的前途 路的前程 城市的前景守望.江的神奇 滩的神话 岸边的神韵品尝.园的风景 家的风采 眼前的风情沐浴.屋的明亮 窗的明净 心底的明朗闽
