Four advantages to help cloud computing dominate the future education market on-demand service

I. INTRODUCTION

The core idea of cloud computing is to manage and dispatch a large number of computing resources with network connection, and form a computing resource pool to serve the users on demand.

Ii. definition

Narrow Cloud computing

A network that provides resources is called a "cloud." The resources in the cloud can be extended indefinitely by the user, and can be obtained at any time, on demand, at any time, and paid for by use. This feature is often called the use of IT infrastructure like hydroelectric power.

Broad Cloud Computing

The cloud is a virtual computing resource that can be maintained and managed, typically for some large server clusters, including compute servers, storage servers, broadband resources, and so on. Cloud computing centralizes all computing resources and is automatically managed by software without human involvement.

One analogy: It's like switching from an old single generator to a centralized power supply model. It means that computing power can also be used as a commodity circulation, like gas, water and electricity, easy to use, low-cost. The biggest difference is that it is transmitted over the Internet.

In general, cloud computing can be counted as a commercial evolutionary version of Grid computing.

Iii. principle

The basic principle of cloud computing is that enterprise data centers run more like the Internet by distributing computations across a large number of distributed computers rather than on local computers or remote servers. This allows the enterprise to switch resources to the required applications and to access the computer and storage systems as needed.

The application of cloud computing consists of the idea of combining forces with each of these members.

Iv. Features

Data Security and reliability

First, cloud computing provides the most reliable and secure data storage center, and users don't have to worry about data loss or virus intrusion.

Many people think that data can only be kept in their own visible, touch the computer is the safest, but it is not. Your computer may be damaged by its own carelessness, or by a virus attack, causing data on your hard disk to fail to recover, and an outlaw who has access to your computer may use every opportunity to steal your data. Conversely, when you upload your photos to a googlepicasaweb-like web album, you don't have to worry about losing or damaging the data. Because at the other end of the cloud, there is the world's most professional team to help you manage your information, with the world's most advanced data centers to help you save your data. At the same time, a strict rights management strategy can help you to share data with someone you specify. This way, you can enjoy the best and safest services without spending money, even more conveniently than saving money in a bank.

Low client demand

Second, cloud computing has the lowest requirements for client devices and is the most convenient to use.

You can directly edit the document stored at the other end of the cloud in the browser, you can always share information with friends, no longer worry about whether your software is the latest version, no longer need to be infected with the software or documents to worry about.

Because at the other end of the cloud, there are professional IT staff to help you maintain your hardware, install and upgrade your software, protect you from viruses and various cyber attacks, and help you do everything you've done on your PC.

Easily share data

In addition, cloud computing makes it easy to share data and applications between different devices. Take the management of contact information for example, when you use Web services to manage all your contacts, you can use any computer to find the e-mail address of a friend, call a friend's phone number directly on any phone, or quickly share a contact's electronic Business card with several friends. Of course, all of this is done under a strict security management mechanism, and only people who have access to the data can use or share the data with others.

May be infinitely many

Finally, cloud computing provides an almost limitless number of possibilities for us to use the web, provides almost unlimited space for storing and managing data, and provides almost unlimited computing power for our various applications. Imagine when you're driving a car, as long as the mobile phone connected to the network, you can directly see the location of their own satellite map and real-time traffic conditions, you can quickly find their own preset route, you can ask the network friends recommend the best nearby scenic spots and restaurants, can quickly book the destination of the hotel, You can also share your photos or video clips that you've just taken to friends and relatives far away ...
