Internet of Things China With the rapid development of the Internet and IT industries, we are pleased to see the continuous emergence and progress of various new technologies over the past 10 years. Cloud is not only given users unprecedented computing power, but with a large scale, virtualization, high reliability, versatility, high scalability and other features, and with on-demand services and low cost and practicality. Cloud has become a technology from the concept of nothingness gradually toward the government, business and even individuals, a variety of cloud-based applications are becoming more mature.
The Internet of Things (IoT), as a further development of the Internet, has more complicated usage scenarios and application requirements, and more needs cloud as an infrastructure and service to support the transmission, analysis, management, application, and so on of huge amounts of data. Therefore, cloud technology is not generated by the Internet of things, but the cloud technology is bound to be applied to the Internet of Things, and play a very important role.
So, what are the current cloud technologies, and these technologies to meet the needs of the development of the Internet of things?
The concept of cloud technology that we are most familiar with is based on the categories of cloud deployments, "private cloud", "public cloud", and "hybrid cloud" that has become popular in recent years. What kind of cloud types are used in what scenarios? We suggest:
1) When users need to operate their own cloud platform in a closed environment, they need to use the private cloud service.
2) When users only have some special requirements on the privacy of the system, they can peel the private system in the architecture design to operate in the private cloud and the rest of the services in the public cloud service. That is, a hybrid cloud.
3) Industry customers without special needs, public cloud + security mechanism still can guarantee system and data security
Next, let's take a look at what technologies cloud technology includes:

The first three cloud security, cloud computing, cloud storage belong to the infrastructure, the past 10 years, the cloud in computing power, virtualization, security and big data and other fields have made a huge technological breakthrough.
The cloud service, as a comprehensive IT architecture application and service platform, helps cloud technologies to be widely promoted and applied to various enterprises and scenarios. It can be said that cloud services are the trend and the future direction.
Cloud services generally refer to public clouds divided into three types based on customer needs: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Users get basic IT infrastructure services (data centers, storage, databases, etc.) over the Internet.
The benefits that users can gain by using IaaS are:
1) Reduce server, network, storage, security and other hardware and software configuration, maintenance overhead
2) Concentrate on the development and operation of industry cloud platform without worrying about the stability of the infrastructure
The software development platform as a service to provide customers with the network, server operating system, etc., by the customer to control the deployment of applications.
The benefits of using PaaS are also obvious:
1) Save platform environment to build and operation time
2) Save on the development and maintenance of basic software services
3) Concentrate on cloud application development in the industry
4) more convenient for the industry to provide cloud services solutions
Software as a Service, which allows users to rent Web-based software from providers to manage their business activities without having to buy software. The concept of software that truly delivers everything.
Due to the different needs of different industries for applications, although SaaS is the cloud service of most concern at present, it is still in the development stage.
Cloud technologies, especially cloud services, can help businesses reduce hardware, software development, and labor costs, as well as address things like data processing, storage and security in the Internet of Things. The combination of cloud technology and the Internet of Things seems to be the perfect combination. Cloud technology solves many problems of the Internet of Things, and the final presentation of the Internet of Things is embodied through cloud technologies. In fact, the future of cloud technology and the Internet of Things is so beautiful? How we will be the rapid pairing of the two?
From the characteristics of cloud technology, in line with the development needs of the Internet of Things.
distributed
The distributed processing, parallel processing and grid computing included in cloud technology are the best solutions to solve the Internet of Things. The network topology of cloud technology is also highly coincident with the Internet of Things network topology. Cloud technology can not only handle a large number of terminal devices concurrently receive data on the server load, while calculating the way to take full account of the collaboration between terminal devices.
Data processing capabilities
Cloud technology is the use of cluster technology to solve a single computer or a small amount of computing can not be done. The most basic function of the Internet of Things terminal device is to generate data, but the number of terminals is huge and the data speed is constant. Therefore, only cloud technology has the capability to handle such a large amount of data.
storage
One of the characteristics of the Internet of things is the huge amount of data that is generated, and the cloud storage technology in cloud technology satisfies the scalable and scalable storage space. This provides a continuum of technical foundations for early deployment and rapid expansion of the Internet of Things.
Big data sharing
The development of the Internet of Things has a high demand for big data sharing. In particular, if cloud services used by different deployment stages of the Internet of Things are inconsistent or different cloud service providers are selected, how to share such huge amounts of data is necessary Only cloud technology can solve it.
