The goal of cloud computing is to manage resources effectively. The main management is to virtualize the above three resources through information technology in three aspects: computing resources, network resources and storage resources to form a resource pool. Flexible management of application software (that is, cloud software deployment) can be achieved by encapsulating commonly used application software (such as database and running environment) and automatically deploying it when standardization is needed.
Big data, or massive data, refers to massive, high-growth and diversified information assets, which need new processing modes to have stronger decision-making, insight and process optimization capabilities.
Internet of Things (IoT) refers to a network that connects everything with the Internet through information-aware devices for information exchange and communication according to the agreed protocol, so as to realize intelligent identification, positioning, tracking, monitoring and management. The Internet of Things mainly solves the interconnection between objects, people and objects, and people.

The concept of cloud computing:
"Cloud" is essentially a network. Cloud computing in a narrow sense is a network that provides resources. Users can access the resources on the "cloud" at any time and use them on demand, which is also considered as unlimited expansion. As long as they pay according to the usage, they can "cloud". Just like a waterworks, we can receive water at any time and pay the waterworks according to the water consumption of our home.
Broadly speaking, cloud computing is a service related to information technology, software and Internet. This pool of computing resources is called "cloud". Cloud computing brings together many computing resources and realizes automatic management through software. Only a few people need to participate, and resources can be provided quickly. In other words, computing power, as a commodity, can be circulated on the Internet. Just like water, electricity and gas, it can be easily obtained and used, and the price is relatively low.
In a word, cloud computing is not a brand-new network technology, but a brand-new network application concept. The core idea of cloud computing is to provide fast and secure cloud computing services and data storage on Internet-centered websites, so that everyone who uses the Internet can use the huge computing resources and data centers on the network.
