What technology is the development and application of cloud computing?

Cloud computing is the development and application of parallel computing, grid computing and distributed computing technology.

I. Definition of cloud computing

Cloud computing is a system that connects a large number of computers and servers to form a virtual supercomputer and provides computing, storage and application services through the network. Users can access cloud resources through various terminal devices (such as PCs, mobile phones, tablets, etc.). ) achieve the effect of using on demand and charging by quantity.

Second, the technical basis of cloud computing

The foundation of cloud computing technology includes virtualization technology, distributed computing and grid computing. Virtualization technology can abstract multiple physical resources into a virtual resource, thus realizing resource sharing and flexible scheduling.

Distributed computing can decompose a large-scale computing task into several small tasks and distribute them to different computers for processing, thus improving computing efficiency. Grid computing can combine computers in different geographical locations into a virtual supercomputer to complete large-scale computing tasks together.

Application fields of cloud computing

I. Enterprise Cloud

Enterprise Cloud is an enterprise-centered cloud computing service, which aims to improve the operation and maintenance level of data centers within enterprises and make the whole IT service more business-oriented. IT can help enterprises realize flexible IT service delivery and improve their innovation ability and competitiveness.

Second, the cloud storage system

Cloud storage system can solve the shortage of local storage management and reduce the data loss rate. It provides cloud storage services by integrating various storage devices in the network, and can manage data storage, backup, replication and archiving. Cloud storage system is very suitable for those enterprises that need to manage and store massive data.

Third, cloud games.

Cloud game is a game mode based on cloud computing technology. All the games run on the server, and the rendered game images are transmitted to users through the network. This game mode does not require users to buy expensive game machines or computer equipment, but only needs simple and easy-to-use operation through the Internet interface, so that voice and video can be shared quickly and efficiently.
