Cloud computing: Cloud computing is a computing method based on the Internet. In this way, shared software and hardware resources and information can be provided to various computer terminals and other devices as required. Cloud computing is another great change following the big shift from mainframe computers to client-servers in the 1980s. Users no longer need to know the details of the infrastructure in the "cloud", do not have to have corresponding professional knowledge, and do not need to directly control. Cloud computing describes a new Internet-based IT service addition, usage, and delivery model, which usually involves the provision of dynamic, easily scalable and often virtualized resources through the Internet.
Fog computing: Fog computing is a distributed computing model that serves as an intermediate layer between cloud data centers and Internet of Things (IoT) devices/sensors. It provides computing, network, and storage devices so that cloud-based services can Closer to IoT devices and sensors. The introduction of the concept of fog computing is also to cope with the challenges faced by traditional cloud computing in IoT applications.
Sea computing: The essence of sea computing is to push intelligence to the forefront. The intelligent front-end has storage, calculation and communication capabilities, can coordinate perception and judgment and decision-making between the front-ends in the local scene space, and respond in time to sensing events, with a high degree of dynamic autonomy. Sea Computing provides users with one-stop Internet-based services, which is the simplest and most reliable interactive mode of Internet demand. As long as the user enters the service demand in the sea computing, the system can clearly identify this demand, and allocate the demand to the optimal application or content resource provider for processing, and finally return the matching result to the user. Compared with the back-end processing of cloud computing, sea computing refers to the front-end processing of smart devices.
Edge computing: Edge computing is a method of optimizing cloud computing systems by performing data processing at the edge of the network near the data source. This reduces the required communication bandwidth between the sensors and the central data center by performing analysis and knowledge generation at or near the data source. This method requires the use of resources that may not be continuously connected to the network, such as laptops, smartphones, tablets, and sensors. Edge computing covers wireless sensor networks, mobile data collection, mobile signature analysis, and collaborative distributed peer-to-peer ad hoc networks And processing can also be classified into local cloud/fog computing and grid/grid computing, dew computing, mobile edge computing, cloud computing, distributed data storage and retrieval, autonomous self-healing network, remote cloud service, augmented reality, etc. Wait
