Most internet users are currently using cloud services, even if they do not realize it. It can adopted by all kinds of users, be they individuals or large enterprises.
Adoption has been enabled by "increased high-speed bandwidth" which makes it possible to receive the same response times from centralized infrastructure at other sites.Ĭloud computing is being driven by providers including Google,, and Yahoo! as well as traditional vendors including IBM, Intel, Microsoft and SAP. By sharing consumable and "intangible" computing power between multiple " tenants", utilization rates can be improved (as servers are not left idle) which can reduce costs significantly while increasing the speed of application development.Ī side effect of this approach is that "computer capacity rises dramatically" as customers do not have to engineer for peak loads. Many cloud computing providers use the utility computing model which is analogous to how traditional public utilities like electricity are consumed, while others are billed on a subscription basis. Characteristics Īs customers generally do not own the infrastructure or know all details about it, mainly they are accessing or renting, so they can consume resources as a service, and may be paying for what they do not need, instead of what they actually do need to use.

Open standards and open source software are also critical to the growth of cloud computing.
Commercial offerings need to meet the quality of service requirements of customers and typically offer service level agreements. The services are accessible anywhere in the world, with The Cloud appearing as a single point of access for all the computing needs of consumers. The majority of cloud computing infrastructure currently consists of reliable services delivered through data centers that are built on computer and storage virtualization technologies. Some successful cloud architectures have little or no centralised infrastructure or billing systems including peer-to-peer networks like BitTorrent and Skype. Ĭloud computing often uses grid computing, has autonomic characteristics and is billed like utilities, but cloud computing can be seen as a natural next step from the grid-utility model.
Īccording to the IEEE, cloud computing is a concept where information is placed on servers and sent over the Internet to other devices, such as computers, laptops, handhelds, and sensors. They do not have to know or control the technologies behind them, preventing them from running into ethical and legal problems. It is a type of computing in which IT-related actions are provided “ as a service”, allowing users to access these services through the Internet ("in the cloud"). Just as how in the real world, clouds hide parts of the sky from sight, the cloud in computing hides the complex infrastructure that makes the Internet work. The cloud is a metaphor for the Internet based on how it is described in computer network diagrams. The idea behind cloud computing is similar: The user can simply use storage, computing power, or development environments, without having to worry how they work behind the scenes. Every month, they pay only for what they used and nothing more. It is like the way in which electricity is sent to users: they simply use the electricity that is sent to them and do not need to worry where the electricity is from or how it is made and brought to them. Cloud computing is when computing services are provided by a company or place outside of where they are being used.
