In cloud computing, the word cloud (also stated as "the cloud") is used as a metaphor for the "Internet", so cloud computing phrase means "a type of computer through Internet" where different services - such as servers, storage and applications - are sent to the computers and devices in an organization through the Internet.
Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers on a network to solve problems harnesses are too intense for any independent machine.
How Cloud Computing Works
The goal of cloud computing is the application of traditional supercomputing, or the power of high performance computing, typically used by military and research facilities to carry tens of trillions of calculations per second, in applications oriented consumer, such as financial portfolios, to provide personalized information to provide data storage or for feeding large computer games, immersive.
To do this, cloud computing using networks of large groups of servers running typical low-cost technology with specialized consumer PC connections to disseminate data processing tasks through them. This shared infrastructure contains large reserves of the systems are joined together. Often virtualization techniques are used to maximize the power of cloud computing.
Cloud Computing Standards
The rules for connecting computer systems and software necessary to make the job of cloud computing are not completely defined at present, leaving many companies to define their own cloud computing technologies. Cloud computing systems offered by companies such as technology "Blue Cloud" IBM, for example, are based on open standards and open source software that link computers together that are used to deliver Web 2.0 capabilities such as mash-ups or mobile commerce.
Cloud Computing in the data center and for small business
Cloud computing has begun to gain wide acceptance in corporate data centers, as it allows the data center to operate as Internet through the training process of computing resources to be accessed and shared as virtual resources a secure and scalable manner.
For a company small and medium (SMB), the benefits of cloud computing is propelling the adoption. In the SMB sector there is often a lack of time and financial resources to acquire, implement and maintain an infrastructure (eg, software, servers and storage) resources.
In cloud computing, small businesses can access these resources and expand or reduce services as business needs change. The common pay-as-you-go subscription model is designed for SMEs to add or remove services easily and usually only pay for what you used.
