What does cloud computing mean?

Cloud Computing (Cloud Computing) is the increase, use and interaction model of Internet-based related services, usually involving the provision of dynamically scalable and often virtualized resources through the Internet.

There are many definitions of cloud computing. The widely accepted definition at this stage is the National Institute of Standards and Technology (NIST):

Cloud computing is a pay-per-use model that provides available, convenient, and On-demand network access into a shared pool of configurable computing resources (resources include networks, servers, storage, application software, services) that can be quickly provisioned with minimal management effort or collaboration with service providers Have very little interaction.

In layman’s terms, cloud computing is computing through a large number of computing resources in the cloud. For example, users send instructions through their own computers to service providers that provide cloud computing, and through a large number of servers provided by the service providers, " Nuclear Explosion" is calculated and the results are returned to the user.

The cloud is a metaphor for the network and the Internet. In the past, cloud was often used to represent telecommunications networks in diagrams, and later it was also used to represent the abstraction of the Internet and underlying infrastructure. Therefore, cloud computing can even allow you to experience 10 trillion calculations per second. With such powerful computing power, you can simulate nuclear explosions, predict climate change and market development trends. Users access the data center through computers, laptops, mobile phones, etc., and perform calculations according to their own needs.

Cloud Computing is Distributed Computing, Parallel Computing, Utility Computing, Network Storage Technologies, Virtualization, and Load Balance (Load Balance), hot backup redundancy (High Available) and other products of the development and integration of traditional computers and network technologies.
