Cloud computing is the most talked about IT service these days. Each and every person is talking about this new concept 'cloud computing.' Cloud computing is overhyped because it is a very old concept. This concept was introduced in the 1960's; however, it is used in a different way today. Cloud computing refers to the usage of software with the help of a browser. Google docs is a very good example of cloud computing. Cloud computing is a concept that is used in IT outsourcing.
Cloud computing is one of the major developments of ICT. The principle is simple: move the computer processing power and data from the workstation (fixed / mobile) to large data centers. Among the main drivers of this transformation include the ubiquity of broadband access and the falling price of storage. The rise of Web 2.0, usability and ergonomics of its online applications, is one of the most striking expressions of this development (Smith, 2009). Attractive to both users and developers, cloud computing relies on the economic model of pay-as-you-go, that is to say pay according to its growth and its individual needs. This model is also the norm in most sectors of the economy.
Cloud Computing
Cloud Computing is an online platform though which you can store or access your documents anytime from anywhere. A cloud computing user is free of the boundaries of a single specific desktop. It not only let you to store documents or files but also the software needed to access and changes them. Its best-known forms in consumer markets are Amazon “S3” and “Google Docs”.
Cloud Computing is efficient and time saving because of the centralized storage, huge memory, speed processing and high bandwidth. The term cloud computing was adapted from the cloud symbol that is used in Internet flowcharts and diagrams very often. The online email services are the most simple example of cloud computing. The service is used without any special software or installation. Only Internet connection is required for using the email service. The server and email service software is all on the cloud i.e. the Internet and is administered by the cloud service provider such as yahoo, hotmail etc. The basic theme of cloud computing is that, if you only need milk, you do not need to buy a cow. As users, do not need to buy a software or hardware to get the benefit of email service.
Cloud Computing describes the approach, abstracted IT infrastructures (e.g, computing capacity, data storage, network capacity, or even finished software) dynamically adapted to the needs of a network to provide. From a user perspective, the provided IT infrastructure abstracted seems distant and solid, as shrouded in a "cloud" to happen (Gozzi, 2010).
Five Essential Characteristics for Cloud Computing
Self-Service Provisioning: Self-assignment of benefits from the cloud or by the user, which should be available when needed.
Scalability: Scalability using the decoupling of fluctuations and infrastructure limitations.
Reliability and fault-tolerance: Reliability and fault tolerance guarantees permanently defined quality standards of the IT infrastructure for ...
