What is cloud computing-the concept of cloud computing

Cloud computing concepts are controversial, the concept of cloud computing is proposed by Google, this is a beautiful network application model. The broad sense is one kind of internet resources utilization New way, may for the populace user relies on the internet heterogeneous, the autonomous service carries on the demand the computation, the cloud computing concept core is, the resource is dynamically easy to expand and the virtualization, provides through the Internet. Cloud computing concept in different fields seems to have a different understanding, since the rise of cloud computing, people began to question the speculation about the concept of cloud computing. More people think that the concept of cloud computing is too biased and opportunistic, so the expectation is that there are cloud computing applications appear.

Cloud computing Concept

The basic principle of cloud computing is that enterprise data centers run more like the Internet by distributing computations across a large number of distributed computers rather than on local computers or remote servers. This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed.

Cloud Computing Core Technology

Building different layers of cloud computing faces different key challenges, such as the need for SaaS services to enhance the user experience in the case of Multi-Tenant, where the PAAs needs to support the development, orchestration and blending of services, Laas to achieve low-cost, highly available, and transparent infrastructure offerings.

In response to these challenges, industry and academia have promoted the development of cloud computing by promoting the core technologies of cloud computing. We believe that cloud computing involves six core technologies as follows:

Virtualization Technology

Large-scale distributed data management technology

Distributed Parallel programming model

Service-oriented application assembly and management

Online service development testing and scheduling technology

Front end display and interactive technology

Cloud Common Key Features

Unified Heterogeneous Platform

Virtualization of physical Resources

Self-help supply

Elastic

How much do you pay?

Programmable control

Implementation steps for Cloud computing

First Stage: Resource Virtualization Integration

Phase two: providing Cloud computing services

Phase III: Intelligent Cloud Computing

Cloud computing Applications

Collaboration tools: Individuals, families, organizations, society through the "cloud" to work together to achieve synchronous processing or continuous;

Service platform: To provide virtualized resource services for various applications or developments that require large-scale computing or storage, and different users can share resources;

Innovation Base: To provide users with APIs, encourage users to make innovative attempts, and constantly emerging new applications or services.

Cloud computing trends

Cloud computing unifies the IT basic resources to provide the personalized service for the user, can say is the perfect combination of the standardization and the difference. The advent of cloud computing shows that the current Internet encounters a new development opportunity. Despite such or such imperfections, cloud computing still shows a more optimistic outlook, driven by the Internet, it and telecoms giants.
