Internet of Things Interpretation and Four Types of Deployment

IoT and cloud computing are comparable in many aspects. For example, cloud computing has three layers of SPI (SaaS, PaaS, and IaaS), and Internet of Things also has DCM (ie, sensing, transport, and application layers). Three layers. NIST (National Institute of Standards and Technology) in the United States divides the cloud computing deployment model into shared cloud, private cloud, community cloud, and hybrid cloud. The existence of the Internet of Things is divided into intranet, private network, and extranet; Computing also divides the IoT deployment model into Public IoT, Private IoT, Community IoT, and Hybrid IoT.

Based on the thinking of NIST (National Institute of Standards and Technology), this article proposes a definition of the Internet of Things and a specification for the architecture of the Internet of Things. It hopes to unify the thinking of the industry and enable us to have a common language and reference in the Internet of Things. Play a role as a brick.

The concept of Internet of Things (IoT) Internet of Things (IoT) refers to Ubiquitous devices and facilities, including devices with “intelligent intelligence” such as sensors, mobile terminals, and industrial systems. House control systems, home intelligence facilities, video surveillance systems, and items with “external enable” (such as RFID assets), individuals or vehicles carrying wireless terminals, etc. Or "animals," through various wireless and/or wired long-distance and/or short-distance communication networks to achieve interoperability (M2M), application of Grand Integration. The Internet of Things can be based on SaaS operating modes such as cloud computing. In the intranet, extranet/VPN, or Internet environment, appropriate information security mechanisms can be used to provide security and control (privacy protection). And even personalized personalized real-time online monitoring, location tracking, alarm linkage, dispatching and commanding, plan management, process control, remote maintenance, online upgrades, statistical reports, decision support, leadership desk (Dashboard) and other management and service functions. "Things" integrated services of "management, control and management" of "high-efficiency, energy-saving, safety and environmental protection".

Four types of deployment methods Private Internet of Things (Private IoT): Providing services within a single organization, which may be implemented and maintained by an organization or a third-party commissioned by it, mainly within an On Premise intranet. Exist in the institution (Off Premise).

Public IoT: Providing services to the public or large user groups based on the Internet, and is generally operated by an organization (or a third party entrusted by it).

Community IoT: To provide services to an associated “community” or community (eg, a city government subordinate bureau, such as public security bureau, transportation bureau, environmental protection bureau, urban management bureau, etc.). It may be coordinated by two or more organizations, mainly in the intranet and private network (Extranet/VPN).

Hybrid IoT: It is a combination of two or more of the above-mentioned Internet of Things, but there is a unified operation and maintenance entity at the back end.
