Cloud computing tutorials for good programmers what are the differences between cloud services and cloud computing? What is cloud, what is not cloud, first of all, cloud computing is indeed very important, cloud computing is indeed a very important technology at present, and will have a very profound impact on the future. However, the current business philosophy of cloud computing, such as cloud TV and cloud mobile phones, makes the cloud completely a business concept. If this continues, it will be difficult for users to distinguish between what is a cloud and what is not a cloud, which is a business concept.

Cloud computing is a real implementation technology. We know that there are many IT resources. For example, we currently have storage resources, computing resources, computers, software, and platforms. Then there are three forms of IT resources, one is centralized, one is decentralized, and the other is distributed. Now in the IT data center, our IT resources exist in a decentralized way, that is, there is no connection between devices. Then cloud computing actually connects the decentralized devices from the network to a distributed system.

Five characteristics of cloud computing. Cloud is defined as a pattern of increase, use, and interaction of related services based on the Internet, usually involving the provision of dynamic, scalable and often virtualized resources over the Internet. Cloud is a metaphor for the Internet and the Internet. In the past, clouds were often used to represent telecommunications networks, and later they were also used to represent the abstraction of the Internet and the underlying infrastructure. Cloud service refers to obtaining the required services through the network in an on-demand and scalable manner. This service can be IT and software, Internet-related, but also other services. It means that computing power can also be circulated through the Internet as a commodity. "

The difference between cloud computing and cloud services:

1. Different concepts:

2. The application prospect is different.

3. Different levels:

4. Different applications

1. Cloud services:

(1), Cloud things

(2) Cloud Security

(3), cloud storage

2. Cloud computing:

(1) Storage Cloud

(2) Medical cloud

(3) Financial cloud

(4) Education Cloud

In the same way, the cloud has such five basic characteristics. The first cloud is composed of cloud elements. Everyone comes from various industries and various aspects, and some of them may be manufactured. You can know that there are many things that can be done in the cloud unit at present. Second, cloud units need to be connected by a broadband network, so the broadband network is the foundation of the cloud. The third feature cloud is the distributed system, the fourth cloud uses virtualization technology, and the fifth cloud is to ensure security. These are the five characteristics of cloud computing
