1. Introduction
The core idea of ​​cloud computing is to uniformly manage and schedule a large number of computing resources connected by the network to form a computing resource pool to serve users on demand.
Second, the definition
Narrow cloud computing
The network that provides resources is called the "cloud". The resources in the "cloud" seem to users to be infinitely expandable, and can be obtained at any time, used on demand, expanded at any time, and paid for per use. This feature is often referred to as using IT infrastructure like hydropower.
Generalized cloud computing
"Cloud" is some virtual computing resources that can be self-maintained and managed, usually some large server clusters, including computing servers, storage servers, broadband resources and so on. Cloud computing centralizes all computing resources and is automatically managed by software without human involvement.
Someone made an analogy: This is like changing from the ancient single generator model to the centralized power supply model of the power plant. It means that computing power can also be circulated as a commodity, just like gas, water and electricity, it is easy to access and cheap. The biggest difference is that it is transmitted via the Internet.
In general, cloud computing can be regarded as a commercial evolution of grid computing.
3. Principle
The basic principle of cloud computing is that by distributing computing on a large number of distributed computers instead of local computers or remote servers, the operation of enterprise data centers will be more similar to the Internet. This allows companies to switch resources to the applications they need and access computers and storage systems as needed.
The application of cloud computing contains such an idea, unite the power and use it for each member.
4. Features
Data is safe and reliable
First of all, cloud computing provides the most reliable and safe data storage center, users no longer have to worry about data loss, virus intrusion and other troubles.
Many people think that data is only safest if it is stored on a computer that you can see and touch, but it is not. Your computer may be damaged due to your carelessness, or be attacked by a virus, so that the data on the hard disk cannot be recovered, and the criminals who have access to your computer may use various opportunities to steal your data. Conversely, when you upload your photos to a web album similar to Google Picasa Web, you no longer have to worry about data loss or damage. Because at the other end of the "cloud", there is the world's most professional team to help you manage information, and the world's most advanced data center to help you save data. At the same time, a strict rights management strategy can help you share data with people you designate with confidence. In this way, you can enjoy the best and safest service without spending money, even more convenient than depositing money in the bank.
Low client requirements
Secondly, cloud computing has the lowest requirements for user equipment and is the most convenient to use.
You can directly edit the documents stored on the other end of the "cloud" in your browser, you can share information with friends at any time, no longer worry about whether your software is the latest version, and no longer need to be infected with software or documents worry. At the other end of the "cloud", there are professional IT staff to help you maintain hardware, help you install and upgrade software, help you prevent viruses and various network attacks, and help you do everything you did on your personal computer.
Share data easily
In addition, cloud computing can easily achieve data and application sharing between different devices. Taking the management of contact information as an example, when you use a network service to manage the information of all contacts, you can use any computer to find the email address of a friend anywhere, you can directly on any mobile phone Dialing a friend's phone number can also quickly share a contact's electronic business card to several friends. Of course, all of this is carried out under strict security management mechanisms. Only those who have access to the data can use or share this data with others.
May be infinite
Finally, cloud computing provides us with almost unlimited possibilities for using the network, almost unlimited space for storing and managing data, and almost unlimited powerful computing power for us to complete various applications. Imagine that when you travel by car, as long as you connect to the Internet with your mobile phone, you can directly see the satellite map and real-time traffic conditions of your area, you can quickly query your preset driving route, and you can invite friends on the network Recommend the best scenic spots and restaurants nearby. You can quickly book a hotel in your destination. You can also share the photos or video clips you just took with your friends and relatives in the distance ...
