How to learn Linux beginners? This knowledge takes you into the world of clouds

The name of cloud computing, not to say is including women, but know with the Internet industry touch a little bit of the reason, how to also be a household. Of course, cloud computing is a term, is a professional term, a lot of friends heard to hear that it is now hot, but also know that cloud computing is a free and rich look, but just do not know what cloud computing is a thing ...

What is cloud computing? It's like using electricity without having to equip a generator, just buy it directly from the power company. "Cloud computing" brings about such a change. By Google, IBM and other professional network companies to build computer storage, computing center, users rely on a network cable with a browser can be easily accessed, the "cloud" as the data storage and application services center.

Cloud computing has now developed two areas of cloud security and cloud storage. such as domestic rising and trend technology has started to provide cloud security products, and Microsoft, Google and other international giants are more involved in the cloud storage domain. Cloud computing is a computing model in which applications, data, and IT resources depend on the network to provide the user with a service.

Cloud computing is also a methodology for infrastructure management, and a large number of computing resources make up it resource pools for dynamically creating highly virtualized resources for user use. In a cloud computing environment, all computing resources, such as servers, can be dynamically generated from the hardware infrastructure and modified to suit the needs of the task.

Cloud computing can support grid computing or non-grid computing, and grid technology is an integral part of cloud computing. Cloud computing relies on transforming physical resources into scalable virtual shared resources that enable enterprises to allocate resources to applications that require resources, i.e. access to resources (computer processors and storage systems, etc.) on demand.

Relying on cloud computing, users can access a large number of compute and storage resources without having to care about their location and how they are configured.

Cloud computing is the development of distributed processing, parallel processing, and grid computing, or the commercial implementation of these concepts of computer science.

It is called "cloud" because it has cloud characteristics in some ways:

The cloud is generally large, the scale of the cloud can be dynamically scaled, its boundary is blurred;

The cloud is erratic in the air, and you can't and does not have to determine its exact location, but it does exist somewhere.

It is called "the Cloud", but also because one of the originator of Cloud computing Amazon company will have been called as the grid computing things, took a new name "Elastic Computing Cloud" (EC2), and achieved commercial success.

The value of the cloud: the full use of resources

The essence of cloud computing is to rely on the consolidation, sharing and dynamic provision of resources to improve it investment utilization, which includes new investment resources and invested resources.

Therefore, the implementation of cloud computing does not need to abandon the original IT infrastructure resources.

Cloud computing can leverage existing IT infrastructure resources, and cloud computing can efficiently monitor and manage IT infrastructure resources. Therefore, the implementation of cloud computing will make resources easier to be fully utilized.
