1, cloud computing

Generally speaking, cloud computing, the cloud that is the network resources, from the cloud to obtain the required service content on demand is cloud computing. Cloud computing refers to the delivery and use of IT infrastructure model, refers to the network on-demand, easily scalable way to obtain the required resources (hardware, platform, software). The network that delivers the resources is called a "cloud". "Resources in the cloud appear to be infinitely scalable to the user and can be accessed at any time, used on demand, scaled at any time, and paid for on a pay-per-use basis. This characteristic is often referred to as using IT infrastructure like utilities. Cloud computing in a broader sense refers to a service delivery and usage model that refers to the availability of needed services in an on-demand, easily scalable manner over a network. Such services can be IT and software, Internet-related, or any other service.

2. Internet of Things

Simple understanding: the Internet of things connected to the Internet of things. The Internet of Things is also known as the sensor network in the international arena, which is another wave of the information industry following the computer, the Internet and mobile communication network. Everything in the world, as small as watches, keys, cars, buildings, as long as embedded in a micro-sensor chip, it becomes intelligent, the object can "automatically speak". And then with the help of wireless network technology, people and objects can "dialog", objects and objects can also be "communication", which is the Internet of Things. With the development of information technology, the Internet of Things industry applications continue to grow. Such as: intelligent transportation, environmental protection, government work, public **** security, safe home, intelligent fire, industrial monitoring, elderly care, personal health, floriculture, water monitoring, food traceability and so on. The big ideal is the smart earth, the current actual life exists and in the construction of the smart city are the concept of the Internet of Things speculation.

3, big data

Big data (big data), is the product of the convergence of real data of many kinds, large flow, large capacity, high value, processing and analyzing speed. Big data, or giant data or massive data resources, refers to the amount of information involved is so large that it can not be achieved through the current mainstream software tools, in a reasonable period of time to capture, manage, process, and organize the information to help business decision-making for more positive purposes.

Big Data's 4V characteristics: Volume, Velocity, Variety, Veracity.

That is: Volume, Variety, Velocity, and Veracity.

4. The relationship between Big Data, Cloud Computing, the Internet of Things (IoT), and the Mobile Internet. Relationships

The Internet of Things corresponds to the sensory and motor nervous system of the Internet. Cloud computing is a collection of the core hardware layer and core software layer of the Internet, and the central nervous system of the Internet sprouts. Big Data represents the information layer (ocean of data) of the Internet, and is the basis for the emergence of Internet intelligence and consciousness. Including the Internet of Things, the traditional Internet, the mobile Internet in a steady stream to the Internet big data layer to converge data and receive data. Cloud computing and the Internet of Things promote the development of big data.
