Basic Overview Of Cloud Services

Cloud services is a term that covers the supply of software and services via the Internet. Facebook including mail clinets such as gmail or hotmail, are examples of cloud computing where the application is located in the cloud and not installed on the computer. For businesses, applications like ERP or distribution system (CRM) are increasingly being moved into the cloud. Data storage or back-up can also be moved into the cloud.

Essentially, this type of computing is a way to provide and utilize the resources of computer systems based on the cloud: a collection of machines, network equipment and software maintained by a supplier such that that consumers can use self-service computers via a network. It entails a shift in trend: instead of getting computing power through the acquisition of hardware and software, the consumer uses power provided by a supplier via the Internet.

Companies no longer use their computer servers, but access online services managed by a provider. Given the complexity of such networks, and the multiplicity of actors, the operation in cloud reduces the continuity and quality of service compared to a professional quality application hosted internally. From the perspective of computer architectures, operating in this manner is in essence, a regression compared to best practices vis-a-vis the market players.

In 2009, less than 10% of respondents to a survey mentioned use of cloud in the field of hosting infrastructure and IT applications. This concept is presented as a major development by some well-known analysts such as Gartner Group. The essential characteristics of this type of computing is worldwide self-service, scalability and openness.

The benefits of cloud computing include flexible access, easy administration and often a simpler and less expensive method of payment. It is also possible to scale cloud servers, if demand increases, you can easily change the configuration. In this way, you are free from the need for sudden investment in expensive hardware. The disadvantages include supply uncertainty, reliance on suppliers or performance problems when systems are running slower – and uncertainty about sensitive data.

Calculations and data processing will be carried out in generic data centers, which can pose a security risk by using a given service without applying available safety systems, such as encryption, passwords, physical authentication in the form of smart cards, fingerprints or other biometric methods. As cloud computing becomes more prevalent hackers are also pre-occupied trying to break down more barriers.

Among other things, it is now possible to find a pure European server, so you are free of the possibility that the U. S. National Security Agency may have access to any sensitive material. The name cloud computing was coined by professionals who were looking for a name for the new computer systems operated by the joint action of disparate elements regardless of their geographical location and the underlying infrastructure.

An example of a public cloud computing service provided, is cloud gaming, also known as gaming on demand. It involves playing video games on your computer while the game software runs on remote servers via streaming. The game is hosted and stored on servers, whose location or characteristics may not be known by the user. It does require media such as CD or equipment (games consoles). Players must only have a computer connected to the Internet, and optionally a joystick.
