Internet of Things
Simple understanding: Things connected to the Internet, that is, the Internet of Things. The Internet of Things is also known as the sensor network in the international arena, which is following the computer, the Internet and mobile communication network after another wave of the information industry. 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.
The IoT industry now consists of five layers: the application layer, the support layer, the perception layer, the platform layer and the transmission layer.
Cloud Computing
Cloud computing is a pay-per-use model that provides available, convenient, on-demand network access to a configurable pool of computing resources*** (resources include networks, servers, storage, applications, services) that can be rapidly provisioned with little administrative effort or interaction with service providers.
Classic Use Case: Apple icloud
Apple icloud is more than just a cloud hard drive, it gives you easy access to everything on all your Apple devices and automatically synchronizes the directories of files, pictures, music, calendars, emails, and contacts across all of them, and, even more intimately, automatically synchronizes the changes you make to all your Apple devices and backs up the old files when you make changes. devices and backup old files. You can opt for the free 5G of storage or spend $24.99 a year on the iTunes Match service, which allows you to listen to music stored in Apple's cloud servers from any Apple device.
Big data
Big data is the equivalent of the massive amount of knowledge that the human brain memorizes and stores from elementary school through college, which can only be digested, assimilated, and recreated to create greater value.
The definition given by McKinsey Global Institute is: a data collection that is so large that it greatly exceeds the capacity of traditional database software tools in terms of acquisition, storage, management, and analysis, and has four major characteristics: massive data scale, rapid data flow, diverse data types, and low value density. The strategic significance of big data technology does not lie in the mastery of huge data information, but in the specialized processing of these meaningful data. In other words, if big data is compared to an industry, the key to the profitability of this industry lies in improving the "processing capability" of data, and realizing the "value-added" of data through "processing". "
It's a good thing that I'm not a big fan of the idea.
The relationship between the Internet of Things and cloud computing
Cloud computing is equivalent to the human brain, the nerve center of the Internet of Things. Cloud computing is an Internet-based model for the addition, use and delivery of related services, usually involving the provision of dynamically scalable and often virtualized resources over the Internet.
The Relationship Between Big Data and Cloud Computing
Big Data and Cloud Computing are as inextricably linked as the positive and negative sides of a coin. Inevitably, big data cannot be processed by a single computer, and must be used in a distributed architecture. It is characterized by distributed data mining of massive amounts of data. But it must rely on cloud computing's distributed processing, distributed databases and cloud storage, and virtualization technologies.
Relationship of Big Data, Cloud Computing and IoT
IoT 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, 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 are driving the development of big data.
