Cloud computing is distributed computing, parallel computing, utility computing, network storage, virtualization, load balancing, hot standby redundancy traditional computer network technology and the integration of the product. Zero-based learning cloud computing, cloud computing to learn how to get started? In recent years, cloud computing has become increasingly Linux reuse, it is no longer just between open source enthusiasts to show off the capital, and has been reflected in many value, especially in the server operating system, has become a senior engineer of operation and maintenance the preferred operating tool.
So how cloud computing to learn it? Then simply chat foundation stage (primary operation and maintenance engineers) cloud computing. To Getting cloud computing as a novice, you need to linux learning routes clear at an early stage, any learning is gradual, so learn linux also requires a certain route:
What is cloud and what is not cloud First, cloud computing is indeed very important, cloud computing is indeed a very important technology currently, but the future will have a very profound impact. However, the current cloud computing business concept, TV clouds, cloud mobile phone, the cloud speculation is entirely a business idea. If so continue, then the user is difficult to distinguish what is cloud and what is not a cloud, which is a business idea.
Cloud computing is a real implementation technology, we know there are a lot of IT resources, such as we currently have storage resources, computing resources, computer, software, platform, IT resources exist in three forms, there is a form of centralized way, mode dispersion form of existence is a form of distributed manner. Now data center, our IT resources exist a decentralized way, which means that there is no association between the device and the device. So cloud computing is actually the existing equipment Contact now scattered by the network up into a distribution system.
Five feature cloud. This is the definition of cloud cloud services are Internet-based increase in the use and interaction patterns related services typically involves providing dynamic and scalable and often virtualized resources via the Internet. Cloud is a network, an Internet metaphor. In view of the past is often a cloud to represent the telecommunications network, it was also used to represent the abstract and the underlying infrastructure of the Internet. Cloud services through a network refers to demand, and scalable way to obtain the desired service. This service can be IT and software, Internet-related, but also other services. It means that computing power can also be used as a commodity circulation via the Internet. "
The difference between cloud computing and cloud services:
1, conceptually different:
2, different prospects:
3, on different levels:
4 different applications
1, cloud services:
(1), United Clouds
(2), cloud security
(3), cloud storage
2, the cloud:
(1), cloud storage
(2), medical cloud
(3) the financial cloud
(4), Education Cloud
In this case there is such a cloud five basic characteristics, the first cloud is composed by a cloud yuan, they come from all sectors, in all aspects, and some may be made to do, you can know which cloud unit currently can do now is A lot of. Second, between the cloud units need to be connected with a broadband network, the broadband network is the basis of the cloud. The third feature is the cloud distribution system, and the fourth is the cloud with virtualization technology, cloud fifth is to ensure safety, which is the five characteristics of cloud computing.
