Cloud computing means accessing servers to do the sorts of things you would otherwise need to have desktop computing to do. If you access Google's word processing services for example, and you create and store a document with that service, that is cloud computing. In principle, you could access a remote server in a server farm to provide to you a complete Windows desktop, and you would run all your favorite Windows applications and store your documents out on that server farm. You could do the same for advanced computing like CAD or financial applications. If you use web based Turbo Tax, for example, that is cloud computing.



Depending on what you are doing with the Citrix product, it might be part of a cloud infrastructure. If the software allows you to run a Windows environment that is using computers that are remote from you, then yes that is cloud computing.



The term cloud computing implies that it is unimportant which server or servers you access to do your work. One you log in, you have the work environment you need and all your documents are available.



Cloud computing is tied to virtualiztion, in that you would like the cloud to serve to you a virtual computer and you would like that computer to conform to the sort of operating system and disk requirements that you need to use.What is cloud computing?
Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.



Cloud computing is a paradigm shift following the shift from mainframe to client鈥搒erver in the early 1980s. Details are abstracted from the users, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This frequently takes the form of web-based tools or applications that users can access and use through a web browser as if it were a program installed locally on their own computer.NIST provides a somewhat more objective and specific definition here. The term "cloud" is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online that are accessed from another Web service or software like a Web browser, while the software and data are stored on servers. A key element of cloud computing is customization and the creation of a user-defined experience.



Most cloud computing infrastructures consist of services delivered through common centers and built on servers. Clouds often appear as single points of access for all consumers' computing needs. Commercial offerings are generally expected to meet quality of service (QoS) requirements of customers, and typically include service level agreements (SLAs). The major cloud service providers include Microsoft, Hewlett Packard, IBM, Salesforce, Amazon and Google.What is cloud computing?
no its not citrix.cloud means a frame realy cloud.this cloud is provided by the isp's.in which we can connect soo many offices .
