On June 6th this year, the Ministry of Industry and Information Technology officially issued 5G licenses to China Telecom, China Mobile, China Unicom and China Radio and Television, and approved four enterprises to operate the "fifth generation digital cellular mobile communication service".

This marks the official entry of China into the first year of 5G commercialization! ? As a non-developer, the 5G era may be hot.

So as a developer, with the arrival of 5G, what opportunities can you seize? ? With the arrival of 5G, the future will surely be the era of cloud +AI+5G.

What is "cloud"? ? Another popular name of "cloud" is server, but in fact, cloud is an abstract concept, while server is a concrete concept. It can be said that the server is a concrete implementation of the cloud.

For example, the traditional OA system, browser +web server, completes the enterprise customization system, that is, the company makes an OA system, rents another server, deploys the OA system to the server, and the company can access the system under the local area network. Although the server is mentioned here, it is not a cloud because the user range of this server is too narrow! 1 "cloud", when we think of this word, we will think of the clouds in the sky, which are very huge and cover a large area.

And what's popular now? OA customized cloud service means that a specialized Internet company has made a popular OA cloud platform (actually a system) and deployed it on a large server. Some companies want to use OA system, and they can customize their business on this OA cloud platform. This internet company charges a corresponding rent every year, and each company can customize its own business on the cloud platform, so we will call this server cloud because it has a wide range of applications and a large audience.

What is the relationship between the 25G era and cloud services? ? With the arrival of 5G, how fast will your network speed reach? ? It is no exaggeration to say that a 100GB HD movie can be downloaded in a few seconds.

Imagine, can you read and write on the hard disk at this speed? How many seconds does it take to copy a 100GB HD movie from the mobile hard disk to your computer with 3.0 USB? I think it should take a few minutes to complete the copy, and it will take half an hour to complete the copy if it is slower.

Since our hard disk can't read and write at 5G speed, why should we use it to store data? Why not store it directly on the network? That is, it is stored on the server and on the cloud, such as Baidu Cloud, millet cloud, Alibaba Cloud, Tencent Cloud and other cloud storage platforms.

At the Google conference many years ago, the president of Google once said that in the future, there will only be one browser in our operating system, and there will be no other software.

At that time, many people thought it was a beautiful dream, but with the arrival of the 5G era, it was no longer a dream and became a perfect reality.

With the advent of the 5G era, the development of the cloud will reach an unprecedented era.

What technologies are the "cloud" made of? ? At present, C, c++ and java are popular server programming languages. Large game servers are generally made of C and c++.

Large web servers (web is a mechanism for accessing servers by using browsers) generally use java.

There are also some small web servers that use php, Python,? . Net.

For example, the servers of League of Legends and the glory of the king generally use C and c++.

And our small portal, such as a company's official website, generally uses php.

The most important cloud we are talking about, such as Taobao website, JD.COM website, Baidu cloud, Alibaba Cloud and other large cloud servers, are all made by Java.

Since Java was founded in 1995, it can be used not only as a cloud server (JavaEE direction), but also for Android mobile application development. In addition, the most popular big data development at this stage is also developed in Java.

This is also the reason why Java has ranked first in the world language popularization rankings for many years.

Fourth, how to meet the opportunities brought by 5G? ? For the comprehensive upgrade of cloud services, seizing the opportunity of cloud upgrade will inevitably become the leader of the new era.

Ma Yun seized the opportunity of e-commerce and founded the largest e-commerce website in China. Yun Teng seized the opportunity of social network and created the largest social platform in China. Lei Jun caught up with the wave of mobile Internet and started his own Internet of Things era. Big data is the foundation of artificial intelligence and cloud computing, and Java is the basic entry language of big data.

Therefore, in the 5G era, people who master Java and big data are the most sought-after and the highest-paid people. Why not come to Yantai Beida Jade Bird Jiahui Computer College to study?
