What is cloud computing

Cloud computing refers to the calculation through a large number of computing resources in the cloud, and then returns the results to the user; cloud computing is the increase, use and interaction mode of related services based on the Internet, usually involving the provision of dynamic information through the Internet Easily scalable and often virtualized resources.

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 opinions on what cloud computing is. The most 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, on-demand network access and is configurable A shared pool of computing resources (resources including networks, servers, storage, application software, services) that can be quickly provisioned with minimal management effort or minimal interaction with service providers.

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.
