云计算技术的特点有哪些(云计算有哪些核心特点)

Cloud computing at the podium will answer your questions:
The characteristics of cloud computing are as follows:
(1) Ultra-large scale
"Cloud "It has a considerable scale. Google Cloud Computing already has more than 1 million servers, and the "clouds" of Amazon, IBM, Microsoft, Yahoo, etc. all have hundreds of thousands of servers. Enterprise private clouds generally have hundreds or thousands of servers. "Cloud" can give users unprecedented computing power.
(2) Virtualization
Cloud computing supports users to obtain application services at any location and using various terminals. The requested resources come from the "cloud" rather than a fixed tangible entity. The application runs somewhere in the "cloud", but users don't actually need to know or worry about the specific location where the application is running. With just a laptop or a mobile phone, everything we need can be achieved through network services, even tasks such as supercomputing.
(3) High reliability
The "cloud" uses measures such as multiple copies of data, fault tolerance, and isomorphic interchangeability of computing nodes to ensure high reliability of services. Using cloud computing is more reliable than using local computers.
(4) Versatility
Cloud computing does not target specific applications. With the support of "cloud", ever-changing applications can be constructed, and the same "cloud" can support the operation of different applications at the same time.
(5) High scalability
The scale of "cloud" can be dynamically expanded and contracted to meet the needs of the growth of application and user scale.
(6) On-demand services
The "cloud" is a huge resource pool that you purchase on demand; the cloud can be billed like tap water, electricity, and gas.
(7) Extremely cheap
Due to the special fault-tolerance measures of the "cloud", extremely cheap nodes can be used to form a cloud. The automated centralized management of the "cloud" eliminates the need for a large number of enterprises to bear the burden of increasingly expensive data center management. Cost, the versatility of "cloud" greatly improves resource utilization compared with traditional systems, so users can fully enjoy the low-cost advantages of "cloud". It often only takes a few hundred dollars and a few days to complete what previously required tens of thousands of dollars. dollars and months to complete.
Cloud computing can completely change people's future lives, but at the same time, we must also pay attention to environmental issues, so that we can truly contribute to human progress, rather than simply improving technology.
(8) Potential dangers
In addition to providing computing services, cloud computing services must also provide storage services. However, cloud computing services are currently monopolized in the hands of private institutions (enterprises), and they can only provide commercial credit. Government agencies and commercial institutions (especially commercial institutions that hold sensitive data like banks) should be wary of choosing cloud computing services. Once commercial users use cloud computing services provided by private organizations on a large scale, no matter how strong their technical advantages are, these private organizations will inevitably hold the entire society hostage with the importance of "data (information)." For the information society, "information" is crucial. On the other hand, data in cloud computing is confidential to cloud computing users other than the data owner, but there are really no secrets to the commercial organizations that provide cloud computing. All these potential dangers are an important prerequisite that commercial institutions and government agencies must consider when choosing cloud computing services, especially cloud computing services provided by foreign institutions.

The three characteristics of cloud computing include ultra-large scale and virtualization, high reliability, versatility and scalability.

1. Ultra-large scale and virtualized

The "cloud" has a considerable scale and supports users to obtain application services at any location and using various terminals. The requested resources come from the "cloud" rather than a fixed tangible entity.

2. High reliability

The "cloud" uses measures such as multiple copies of data, fault tolerance, and isomorphic and interchangeable computing nodes. Cloud computing uses Reliable using local computer.

3. Versatility and scalability

Cloud computing is not targeted at specific applications. The same "cloud" can support the operation of different applications at the same time. The scale of the "cloud" can be dynamically expanded to meet the needs of application and user scale growth.

The problem of imperfect laws and regulations regarding cloud computing technology

The imperfect laws and regulations related to cloud computing technology are also a major problem. For the effective role of computing technology, its relevant laws and regulations must be improved. At present, laws and regulations are not yet perfect, and the role of cloud computing technology is still restricted.

As far as the current application of cloud computing technology in computer networks is concerned, it lacks complete security standards, lacks complete service level agreement management standards, and there is no clear responsible person to bear legal responsibility for security issues. In addition, the lack of a complete loss calculation mechanism and liability assessment mechanism for cloud computing security management, and the lack of legal regulations also restrict the development of various activities, making it difficult to guarantee the security of cloud computing in computer networks.
