IaaS (Infrastructure as a Service): Infrastructure as a Service.
With IaaS, you can outsource your recommendations to other places. IaaS companies will provide off-site servers, storage and network hardware, and can also choose to rent them. Save maintenance costs and office space, companies can use this hardware to run their applications at any time. (Server and hardware equipment)
PaaS (Platform as a Service): Platform as a Service.
Sometimes it is also called middleware. All development can be carried out at this level, saving time and resources. PaaS companies can provide a variety of solutions for developing and distributing applications, such as virtual servers and operating systems, which can save on hardware costs. (Providing a service platform for servers and hardware equipment)
SaaS (Software as a Service): Software as a Service.
At the level where ordinary users are most exposed to, applications on any remote server on the network belong to SaaS. For example, Alibaba's DingTalk and Apple's iCloud both fall into this category. (Providing complete software services)
IOT (Internet Of Things) The Internet of Things is also called sensor network. In short, it is the extension of the Internet from people to objects.
The Internet of Things refers to a huge network formed by combining various information sensing devices, such as radio frequency identification devices, infrared sensors, global positioning systems, laser scanners, etc. with the Internet. Its purpose is to connect all items to the network for easy identification and management.
IoE (Internet of Everything) The Internet of Things is a concept recently proposed by Cisco, which is more advanced on the basis of IoE. We are moving from today's "Internet of Things" to the era of "IoE: Internet of Everything", where everything will gain contextual perception, enhanced processing power and better sensing. Adding people and information to the Internet, you will get a network that gathers one billion or even trillion connections. These connections create unprecedented opportunities and give silent things sounds.
AIoT (artificial intelligence Internet of Things) = AI (artificial intelligence) + IoT (Internet of Things).
AIoT integrates AI technology and IoT technology, generates and collects massive data in the cloud and edge through the Internet of Things, and then realizes the dataization and intelligent connection of everything through big data analysis and higher forms of artificial intelligence. Internet of Things technology and artificial intelligence pursue an intelligent ecological system. In addition to the need for continuous innovation in technology, the implementation and application of technology are also the core issues that need to be broken through in the fields of Internet of Things and artificial intelligence at this stage.
