云计算演讲PPT

使用Amazon EC2云服务托管网站，Amazon S3服务备份图书馆集成系统，还计 划用Flickr和Amazon EC2服务做未来的数字馆藏
Exercise: A Library in the Cloud?
What will Cloud Computing bring to our library? 云计算会给图书馆带来怎样的变化? Should each individual library pay attention to it?
云计算是前十五个重要的技术发展趋势之一；
尽快开始对云计算的投入可以保证你获得必要的经验去享用云计算带来的各个方面 的多种多样的好处； 最终使得你所负责的机构成为一个更有效率的和反应迅速的服务提供者。
What is it? 云计算是什么？
Wikipedia Definition The term cloud is used as a metaphor for the Internet, based on the cloud drawing used to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. 云是Internet的比喻。计算机网络图中使用云图形来抽象表现底层架构。 serious definitions McKinsey: “Clouds are hardware-based services offering compute, network and storage capacity where: Hardware management is highly abstracted from the buyer, Buyers incur infrastructure costs as variable OPEX(operational expenditure), and Infrastructure capacity is highly elastic”
“spending on IT cloud services will triple in the next 5 years, reaching $42 billion & capturing 25% of IT spending growth in 2015 and nearly a third of growth the following year. With the overall IT market spend being $383 billion, this kind of growth validates that the opportunity deserves the attention it is getting” 到2015年云服务支出将增长三倍达到$420亿，占IT增长的1/4；证实了一种我们必须 关注的机会。
