Cloud computing and the Internet of Things each have many advantages. Combining cloud computing with the Internet of Things, we can see that cloud computing is actually equivalent to a person‘s brain, and the Internet of Things is its eyes, nose, ears and limbs. Cloud computing is the cornerstone of the development of the Internet of Things, and the Internet of Things has promoted the development of cloud computing. The two complement each other and benefit both.
Cloud computing promotes the realization of the Internet of Things from two aspects:
First of all, cloud computing is the core of the Internet of Things. It is possible to use the cloud computing model to enable real-time dynamic management and intelligent analysis of various items in the Internet of Things. The Internet of Things (IoT) fully utilizes new technologies such as radio frequency identification technology, sensing technology, and nanotechnology in various industries to fully connect various objects and send various real-time dynamic information collected to computer processing centers through wireless networks. Summarize, analyze, and process. The three cornerstones of building the Internet of Things include:
1. Electronic components such as sensors;
2. Transmission channels, such as telecommunication networks;
3. Efficient, dynamic, and scalable technology resource processing capabilities
The third cornerstone: “Efficient, dynamic, and scalable technology resource processing capabilities” is achieved through cloud computing.
Second, cloud computing promotes the intelligent integration of the Internet of Things and the Internet to build a smarter planet. The convergence of the Internet of Things and the Internet requires a higher level of integration, which requires “more thorough perception, safer interconnection, and deeper intelligence”. This also requires relying on efficient, dynamic, and scalable technology resource processing capabilities, which is what the cloud computing model excels at. At the same time, the innovative service delivery model of cloud computing simplifies the delivery of services, strengthens the interconnection between the Internet of Things and the Internet, and enables rapid innovation of new business models and the intelligent integration of the Internet of Things and the Internet.
Putting the Internet of Things and cloud computing together is really because the Internet of Things and cloud computing are very closely related. The four components of the Internet of Things: sensory identification, network transmission, management services and integrated applications, the middle two parts will use cloud computing, especially the "management services". Because of the massive data storage and computing requirements, using cloud computing is probably the most cost-effective way.
The combination of cloud computing and the Internet of Things can be divided into the following types:
One is a single center, multiple terminals. In this model, the smaller IoT terminals (sensors, cameras, or 3G mobile phones, etc.) in the distribution range use the cloud center or part of the cloud center as the data/processing center, and the information and data obtained by the terminal are uniformly processed by the cloud center. Storage, the cloud center provides a unified interface for users to operate or view.
There are many such applications, such as monitoring of community and home, monitoring of a highway section, supervision of kindergarten children, and protection of certain public facilities. This kind of cloud center for major applications can provide mass storage, unified interface, hierarchical management and other functions to provide better help for daily life. Generally, such cloud centers are mostly private clouds.
The second is multi-center, a large number of terminals. For many enterprises and units with a large regional span, multi-center, large-scale terminal models are more suitable. For example, a company that spans multiple regions or countries may monitor the production processes of its companies or factories, and track the quality of related products, because of its large number of branches or branches.
Of course, in the same way, some data or information needs to be shared to users of each terminal in time or in real time. To give a simple example, if the Beijing Earthquake Center detects an earthquake 10 minutes after a certain place and a certain place, it only needs to use this route to send out the information of the detection situation in just ten seconds, so as to avoid unnecessary Loss. China Unicom’s “Connected Cloud” idea is based on this idea. The premise of this model is that our cloud center must contain public and private clouds, and there is no barrier to the interconnection between them. In this way, some confidential things, such as corporate secrets, can be kept secret without affecting the transmission and dissemination of information.
The third is information, application layered processing, massive terminals. This model can be built for a wide range of users, such as a wide range of information and data, and high security requirements. At present, customers are increasingly demanding a variety of massive data processing. In response to this situation, we can make a reasonable allocation according to customer needs and the distribution of cloud centers.
For those that require a lot of data transfer, but the security requirements are not high, such as video data, game data, etc., we can take the local cloud center processing or storage. For the high computing requirements, the amount of data is small, can be placed in the cloud center dedicated to high-end computing. For information and data with very high data security requirements, we can put it in a cloud center with a disaster recovery center.
This mode is to classify various information and data according to the application mode and scenario, and then select relevant channels to the corresponding terminals. The above three are just a rough outline of the combination of cloud computing and the Internet of Things, and there are many other specific modes. As far as the author is concerned, there may already be many modes or methods already in practical use.
