The cloud is a term for a group of servers offering a service. So if your hosting(storing) your data in the cloud it means you have signed up for a service that allows you to remotely store and retrieve your data.
The data will be stored on a physical server some where but the benefit of the cloud is you don't have to worry about the how and maintaining the hardware/software. Though you do have to trust your data to someone else.
The name Cloud comes from the fact that the symbol for the Internet in network diagrams usually is a cloud.
Now that beeing said storing data in the Cloud doesn't mean anything except that it's stored somewhere on one or multiple server's harddrives in a datacenter somewhere around the world. Depending on the service you choose to use of cause.
What Cloud services change are just two things. First of all they make it possible for everyone to access their stored data from anywhere through common web technologies. In the past services like this were often only possible for large corporations with custom setups and huge costs. Second they offer these services in a variety of package sizes fitting for everything from personal use to small and medium sized businesses and even enterprises.
Storing a data on the "Cloud" refers to the remote storage of data. Often this involves internet based services (such as Dropbox, SugarSync etc..).
Basically, these services run data centres that deploy a middleware which enables these services to pool the storage resources from commodity servers. Therefore, they have tons of storage space which they can use to sell over the internet.
To understand this, it is essential to know the basics of cloud. A cloud is basically a cluster of multiple dedicated servers attached within a network. The architecture is such that the entire resources such as CPU, RAM, storage etc. are combined together that forms a large pool. When an application/website is hosted in a cloud infrastructure, it means the resources would be served from this pool.
Now, unlike the traditional hosting types where if the server hardware fails for some reason, your application or websites tend to go unresponsive causing a downtime, but in cloud, despite one of the servers within the cluster going down, your application/website wouldn't face any downtime, which is one of the most essential requirements of todays highly competitive industry. You can access your data from anywhere provided you have access to the Internet. ;)

云是一组提供服务的服务器的术语。因此，如果您在云中托管（存储）数据，则意味着您已经注册了一项允许您远程存储和检索数据的服务。
数据将存储在某个位置的物理服务器上，但云的好处是您不必担心硬件/软件的使用和维护。尽管您确实必须将您的数据信任给其他人。
这是一篇关于它的好文章 http://www.pcworld.com/businesscenter/文章/164933/cloud_computing_explained.html

here is a good article on it http://www.pcworld.com/businesscenter/article/164933/cloud_computing_explained.html
基本上，这意味着您的数据可以通过互联网访问并可靠地存储。
Basically it means that your data is accessible from internet and is reliably stored.
云这个名字来源于网络图中互联网的符号通常是云。
现在，人们所说的将数据存储在云中并没有任何意义，只是它存储在世界各地数据中心的一台或多台服务器硬盘上的某个位置。取决于您选择使用的服务的原因。
云服务改变的只是两件事。首先，它们使每个人都可以通过通用网络技术从任何地方访问其存储的数据。过去，此类服务通常只有具有定制设置且成本高昂的大公司才能实现。其次，他们以各种包装尺寸提供这些服务，适合从个人使用到中小型企业甚至企业的各种需求。

“云”存储数据是指数据的远程存储。这通常涉及基于互联网的服务（例如 Dropbox、SugarSync 等）。
基本上，这些服务运行的数据中心部署了一个中间件，使这些服务能够从商用服务器集中存储资源。因此，他们拥有大量的存储空间，可以用来在互联网上销售。

要理解这一点，有必要了解云的基础知识。云基本上是网络中连接的多个专用服务器的集群。该架构将CPU、RAM、存储等全部资源组合在一起，形成一个大池。当应用程序/网站托管在云基础设施中时，这意味着资源将从该池中提供。
现在，与传统的托管类型不同，在传统的托管类型中，如果服务器硬件由于某种原因发生故障，您的应用程序或网站往往会无响应，从而导致停机，但在云中，尽管集群中的其中一台服务器发生故障，您的应用程序/网站也不会发生故障。不会面临任何停机，这是当今竞争激烈的行业最基本的要求之一。只要您可以访问互联网，您就可以从任何地方访问您的数据。 ;)
