What is cloud computing?

Cloud technology refers to a hosting technology that unifies a series of resources such as hardware, software and network in a wide area network or a local area network to realize data calculation, storage, processing and enjoyment.

Cloud technology is the general name of network technology, information technology, integration technology, management platform technology and application technology based on cloud computing business model, which can form a resource pool and be used on demand, flexible and convenient. Cloud computing technology will become an important support.

Its characteristics are different from ordinary computers:

1. The new distributed architecture and the parallel computing of various cheap computing resources have greatly improved the computing speed and storage capacity of IT infrastructure.

2. Support massive structured and unstructured data processing.

3. The computing power is dynamically scalable, which can meet the changes of users' business needs.

4. Super fault-tolerant ability, even if the node computing resources fail, it can continue to complete the specified tasks correctly, and can take out and replace the damaged node computing unit or storage unit without cutting off the power supply of the cloud computer, thus improving the expansibility, flexibility and timely recovery ability of the whole machine.

5. Collaborative rapid deployment technology greatly improves the deployment speed, efficiency and quality of big data users.
