The use of the cloud metaphor is credited to General Magic communications employee David Hoffman, based on long-standing use in networking and telecom. In addition to use by General Magic itself, it was also used in promoting AT&T 's associated Personal Link Services.
Companies can cut costs with cloud communications services without sacrificing features. [4] The success of Google and others as cloud-based providers has demonstrated that a cloud-based platform can be just as effective as a software-based platform, but at a much lower cost. Voice services delivered from the cloud increases the value of hosted ...
Cloud bursting is an application deployment model in which an application runs in a private cloud or data center and "bursts" to a public cloud when the demand for computing capacity increases. A primary advantage of cloud bursting and a hybrid cloud model is that an organization pays for extra compute resources only when they are needed. [ 68 ]
This exchange of messages is an example of inter-process communication. To communicate, the computers must have a common language, and they must follow rules so that both the client and the server know what to expect. The language and rules of communication are defined in a communications protocol. All protocols operate in the application layer ...
This is the equivalent to infrastructure and hardware in the traditional (non-cloud computing) method running in the cloud. In other words, businesses pay a fee (monthly or annually) to run virtual servers, networks, storage from the cloud. This will mitigate the need for a data center, heating, cooling, and maintaining hardware at the local level.
The rise of cloud computing was enabled by a convergence of powerful, low-cost computer hardware, high-capacity networks, and advances in hardware virtualization.To satisfy high consumer demand for visually-based entertainment such as video and gaming, as well as online social interaction, service providers began to deploy visually oriented applications in centralized data centers and use ...
Sky computing is a paradigm that aims to develop cloud computing model further. It aims to combine existing clouds of different service providers into a comprehensive, interoperable sky. The concept behind sky computing is to create a cloud of clouds that behaves in a similar way to the internet, which consists of a network of networks.
Dew computing [1] is an information technology paradigm that combines the core concept of cloud computing with the capabilities of end devices (personal computers, mobile phones, etc.). [2] It is used to enhance the experience for the end user in comparison to only using cloud computing . [ 3 ]
