CLOUD COMPUTING

        Cloud computing (English: cloud computing) is the combined use of computer technology
('computing') and the development of Internet-based ('cloud'). Clouds (cloud) is metefora from the
internet, as the clouds that often depicted in computer network diagrams. As the clouds in a computer
network diagram, the cloud (cloud) in Cloud Computing infrastructure is also an abstraction of the
complex was hiding. She is a method of computing in which information technology-related capabilities
is presented as a service (as a service), so users can access it via the Internet ("in the cloud") without
knowing what was inside, an expert with it, or have control over the technology infrastructure that
helped. According to a paper published in 2008 IEEE Internet Computing "Cloud Computing is a
paradigm in which information is permanently stored in servers on the Internet and temporarily stored
on the user's computer (client) including the desktop, tablet computers, notebooks, wall computers,
handhelds, sensors, monitors and others.

        Cloud computing is a concept That includes SaaS, Web 2.0, the latest technology trends and
other well-known, with the common theme is reliance on the Internet to Provide the computing needs
of users. For example, Google Apps provides common business applications are accessed through the
online That a web browser with software and data stored on the server.

        Cloud computing refers to a logical computing resources (data, software) can be accessed via
computer networks, not from the local computer. The user or client can perform tasks such as word
processing, with clients such as browsers and with the services provided through the cloud-based
resources such as computing. Because the cloud is the underlying delivery mechanism, cloud-based
long-distance applications and services can support all types of software applications or services that are
currently used.

        In the past, such tasks as word processing is not possible without installing software on
the local computer. With the development of Local Area Networks and wider bandwidth,
multiple CPUs and data storage devices can be used as a place for services such as word
processors run in a remote datacenter. The Cloud computing eliminates the hassles of installation
and upgrades and the need for higher computing power of users and give more control to the
administration service providers.

         Consumers now routinely use data-intensive applications driven by cloud technology previously
unavailable because of cost and complexity of deployment. In many companies, employees and
departments of the company that brought the flood of consumer technologies into the workplace,
which improves compliance and security for corporate law
The term "software as a service" is sometimes used to describe the programs offered through "The
Cloud".A common abbreviation for cloud computing services provided (or even an aggregation of all the
existing cloud service) is "The Cloud".

        An analogy to explain cloud computing is the public utilities such as electricity, gas, and water.
Centralized and standardized utility difficulty freeing individuals from the power plant or pumping
water. All the tasks of development and maintenance involved in doing so is alleviated. With cloud
computing, this translates into reduced costs in the distribution of software to providers are still using
hard media such as DVDs. consumer benefits that the software no longer needs to be installed and
automatically updated, but the savings in the form of money yet to be seen.

        The principle behind the cloud is that every computer connected to the Internet connected to
the same pool of computing power, applications, and files. Users can store and access personal files
such as music, pictures, videos, and bookmarks or play games or do word processing on a remote server
rather than carrying around a physical storage media such as DVDs or thumb drive.Bahkan they use the
web-based email like Gmail, Hotmail, Yahoo , a company's email, or even e-mail client program like
Outlook, Evolution, Mozilla Thunderbird, or Entourage is an email server utilizing the cloud.
