What does cloud computing feature include?

The National Institute of Standards and Technology (NIST) defines: cloud computing is a pay-per-use model that provides available, convenient, on-demand network access and access to a configurable pool of computing resources (resources including networks, servers, storage, application software, Services), these resources can be delivered quickly, with little or no management effort, or with minimal interaction with service providers.

As can be seen from the definition of Cloud Computing, the cloud computing backend has a very large and reliable cloud computing center, for the cloud users, under the premise of paying a small amount of cost, you can get a high user experience! Powerful cloud computing also has the following features:

1. Ultra- Large scale

Cloud computing is ultra-large,Google cloud computing has more than a million servers,Amazon,IBM, Microsoft,Yahoo Cloud computing has hundreds of thousands of servers, and enterprise private clouds typically have hundreds of thousands of servers, and cloud computing centers can empower users with unprecedented computing and storage capabilities by consolidating and managing these huge clusters of computers.

2. abstraction

Cloud computing has a very good terminal support, users in any location, the use of a variety of terminals to obtain cloud-based application services, only through the network to achieve our required operations, even including supercomputing tasks.

3. High Reliability

Cloud computing has high reliability requirements, such as data multi-copy fault tolerance, heartbeat detection and compute node isomorphism can be used to ensure the high reliability of the software and hardware, as well as redundant design of energy, refrigeration and network connection at the facility level to further guarantee the reliability of the service.

4. versatility

Cloud computing is not specific to the application, under the "cloud" support can construct a variety of applications, the same "cloud" can support different applications at the same time to run.

5. High Scalability

Cloud computing is highly scalable, its scale can be adjusted and dynamically scaled according to the needs of its application, and can meet the needs of user application and large-scale growth.

6. On- demand Services

Cloud computing using on-demand service model, users can purchase according to demand, reduce user input costs, and get better service support!

7. cheap

Automated, centralized management of cloud computing enables a large number of organizations to enjoy excess cloud computing resources and services without burdening their increasingly expensive data center management costs, often costing as much as $ hundreds of to complete tasks that previously required $ tens of thousands of.

8. Automation

Cloud computing, whether it is the deployment of applications, services and resources, or the management of hardware and software, is implemented and managed primarily in an automated manner, greatly reducing the huge human cost of the entire cloud computing center.

9. Energy Saving and environmental protection

Cloud computing technology can consolidate workloads across a wide variety of low-utilization servers into the cloud to improve resource efficiency, and the cloud is managed by a professional management team, so its PUE(Power Usage Effectiveness, The value of the power usage efficiency value is much better than the average enterprise's data center, for example, the PUE value of theGoogle Datacenter is around 1.2 , meaning that every dollar of electricity is spent on computing resources, Just spend two cents on electricity in refrigeration and other equipment, and the common PUE between 2 and 3 , and can also be built in the water power plant and other clean resources, so as to further save energy expenditure, but also protect the environment.

Perfect operation and maintenance mechanism

At the other end of the cloud, there are some of the world's most professional teams that help users manage their information and have the world's most advanced data centers to help save data. At the same time, strict rights management policies can guarantee the security of these data. This way, users can enjoy the most professional service without spending a lot of money.

Above is Cloud ComputingThe characteristics of these features, the existence of which makes Cloud Computingcan provide users with more convenient experience and lower cost, at the same time, the existence of these features, is also Cloud ComputingOne of the most important reasons to stand out and be admired by most people in the industry.
