云计算 毕业论文外文翻译.docx

cloud computingcloud computing is a service provided by way of a dynamic scalable virtualized computing model resources over the internet. this mode offers available , convenient , on-demand network access into a shared pool of computing resources can be configured ( resources, including networks, servers, storage , applications, services ) , these resources can be quickly provided , just put it less administration , or with service providers rarely interact . it is calculated by the distribution of the large number of distributed computers, rather than the local computer or a remote server, running enterprise data centers and the internet will be more similar. this allows companies to switch to the application of the resources required , according to demand access to a computer and storage systems. like a single generator from the old model to a centralized power plant model . it means that computing power can also be used as a tradable commodity , like gas, water and electricity , as access to convenient , inexpensive. the biggest difference is that it is transmitted through the internet. cloud computing service characteristics and nature of clouds, water circulation on the internet has a certain similarity , so the cloud is a very apt analogy. cloud computing proposed for the development of computers played a role in making the network more widely based . in my opinion cloud computing has four significant advantages : cloud computing provides the most reliable and secure data storage center , users do not have to worry about data loss, virus attacks and other problems ; cloud computing client devices require a minimum , is also the most convenience ; cloud computing data and applications can be easily shared between different devices ; cloud computing as we use the network provides almost infinite number of possibilities. but on the other hand there are also disadvantages two aspects : first, it is safe , because the cloud computing power and data in the cloud , how to ensure the security of customer data is a relatively important . security has two aspects, one is the data is not lost , the general service providers will have the ability to solve backup , but also occurs occasionally lost ; another is that your data will not leak , although this will take some measures to service providers , not to outsiders , such as hacker attacks to get data , but the problem is the service provider s internal staff is great . the second is the network delay or interruption. cloud computing generally remote access via the network, although it is now improving speed quickly, and lan but compared to the speed or delays , and if once a network outage , the service will not be able to access . 云计算 云计算是一种通过internet以服务的方式提供动态可伸缩的虚拟化的资源的计算模式。这种模式提供可用的、便捷的、按需的网络访问， 进入可配置的计算资源共享池（资源包括网络，服务器，存储，应用软件，服务），这些资源能够被快速提供，只需投入很少的管理工作，或与服务供应商进行很少的交互。 它通过使计算分布在大量的分布式计算机上，而非本地计算机或远程服务器中，企业数据中心的运行将与互联网更相似。这使得企业能够将资源切换到需要的应用上，根据需求访问计算机和存储系统。好比是从古老的单台发电机模式转向了电厂集中供电的模式。它意味着计算能力也可以作为一种商品进行流通，就像煤气、水电一样，取用方便，费用低廉。最大的不同在于，它是通过互联网进行传输的。 互联网上的云计算服务特征和自然界的云、水循环具有一定的相似性，因此，云是一个相当贴切的比喻。 云计算的提出对计算机的发展起到了一定的作用，使得网络更加的广泛化。以我看来云计算有四个显著优点：云计算提供了最可靠、最安全的数据存储中心，用户不用担心数据丢失、病毒入侵等麻烦；云计算对用户端的设备要求最低，使用起来也最方便；云计算可以轻松实现不同设备间的数据与应用共享；云计算为我们使用网络提供了几乎无限多的可能。 但是另一方面也有两个方面的缺点：首先是安全，因为云计算计算能力和数据都在云里，如何保证客户数据的安全就是比较重要的了。安全有两个方面，一个是数据不会丢失，这个
