In layman's terms, cloud computing is the step of processing data on the remote end of the network, because the data processing performance of personal devices such as cell phones, tablet PCs and personal computers (CPU, memory, hard disk and GPU, etc.) is very limited, and allow users to buy more than 100,000 or even millions of high-performance servers is very impractical; In addition, individuals use ordinary broadband, when the external In addition, individuals use ordinary broadband, when a large number of external access to internal servers (game servers and web servers, etc.) is extremely unstable, if the installation of a fixed IP line will be extremely expensive; secondly, individuals and private enterprises sometimes need some of the platform's professional software services. Cloud computing is to solve the above pain points proposed, the large companies in the state of idle servers and other network facilities (IAAS, PAAS) and software services (SAAS) centralized management and distribution, the processing performance (CPU, memory, hard disk and GPU, etc.) and software services leased to the user.

Cloud computing makes it easy to work on the move, when traveling on business with only a laptop and there is a need to deal with big data processing such as video production and image rendering, simply by remotely accessing the cloud host and letting the cloud host handle it. Like the current Huawei's mate10 and Samsung's note8 and other cell phones support peripherals (keyboard and mouse, etc.) is to realize the mobile office, the notebook do not have to bring.

Cloud computing (cloud computing) is an Internet-based model for the increase, use and delivery of related services, usually involving the provision of dynamically scalable and often virtualized resources over the Internet. Cloud is a metaphorical term for network and internet. In the past, clouds were often used in diagrams to denote telecommunication networks, but later also used to denote the abstraction of the Internet and the underlying infrastructure. Thus, cloud computing even allows you to experience computing power of 10 trillion times per second, and having that much computing power can simulate nuclear explosions, predict climate change and market trends. Users access data centers through computers, laptops, cell phones, etc., and perform computing on their own terms.?

There are various definitions of cloud computing. At least 100 explanations can be found for what exactly cloud computing is. The one that is widely accepted at this stage is the National Institute of Standards and Technology (NIST) definition: Cloud computing is a pay-per-use model that provides available, convenient, on-demand network access to a configurable pool of computing resources*** (resources include networks, servers, storage, applications, services) that can be rapidly provisioned with little management effort or interaction with the service provider.

These resources can be rapidly provisioned with little management effort or interaction with service providers.
