What services does Linux cloud computing provide

Scenario 1: games, lol, csgo, peace elite, etc. based on the cloud computing platform and dynamic expansion to maintain stability.

Scenario 2: blockchain

Blockchain technology is in the development stage in China, the main thing is that the blockchain website architecture security, but also the core of cloud computing.

Scenario 3: smart home

Huawei, Xiaomi major manufacturers of smart home behind the massive amount of data, the need to use the results of the processing and analysis to ensure that the user's best experience and to meet the needs of the user, the business data processing support behind the distributed storage and analysis of big data.

Scenario 4: Webcasting

B station live, Shake live, Taobao live all kinds of live broadcasting and live with the goods behind the thousands of servers support, batch maintenance and upgrading, traffic control, automated management.

Scenario 5: network security

Previously, our security is achieved through hardware firewalls, open-source firewalls, in the context of the increasingly powerful Internet, high traffic and high concurrency scenarios is a new challenge to security, we need to cloud computing diversion and behavioral detection, and ultimately to ensure security.

Scenario 6: 5G communication

Previously, the 4G era of Internet sites and traditional PC sites are similar to the 5G era, the site to cope with the high traffic access, a variety of caching, message queuing, CDN architecture and other issues, you must use the cloud computing to solve such problems.

Scenario 7: cloud phone, cloud computer

From the 2020 fire of the cloud phone, cloud computer from the fundamental solution to the problem of everyone's cell phone, computer performance is not uniform. You only need a "monitor" that can access the Internet to connect to the use of cloud phones/cloud computers, cloud phones/cloud computers behind the core technology is cloud computing.

Scenario 8: Internet of Things (IoT) architecture

IoT (Internet of Things) Internet of Things (IoT), so that everything is connected through the network, the smart home, unmanned, the architecture of the Internet of Things, the platform behind the platform is the cloud computing platform and cloud servers.

Reason for recommendation 1: strong national support

Since the release of the Ministry of Industry and Information Technology's "Three-Year Action Plan for the Development of Cloud Computing (2017-2019)" in 2017, the local government has continued to introduce policies to actively promote the enterprise to the cloud, and the scale of the enterprise's demand for cloud computing will be rapidly expanding, which will be conducive to the rapid development of cloud computing.

National level: 1 million new cloud enterprises in 2020

Local level: 1.303 million new cloud enterprises in 19 provinces and cities in 2020

Recommended reason 2: the position is important and indispensable

Baidu's servers were attacked at 7 a.m. on January 12, 2010, with a loss of more than $100 million in five hours. In this five-hour-long hacking event, hundreds of thousands of Baidu's corporate clients were negatively affected psychologically, and were even unable to sustain their operations and went bankrupt and closed their doors under the continuous attacks by hackers.

December 7, 2017 at about 11 o'clock,hollister, Meituan servers appeared to have a large-scale collapse, including takeout, group buying and other businesses are affected, just about ten minutes loss of 12 million.

Recommendation reason Shun 3: comply with the background of the development of the times

Computer development to the present has experienced the hardware era ---- network era ---- application software era ---- mobile Internet era ---- Internet + era ---- big data era, and has entered the era of cloud computing, artificial intelligence, 5G, Internet of Things, information security.

linux belongs to the big data, 5G, artificial intelligence, the Internet of Things infrastructure, but also an important guarantee of information security system, the Internet wave after wave to maturity, but has never shaken the core position of Linux.

Recommended reason 4: less competition, high salary

By the end of 2020, the country **** there are 2,688 general institutions of higher education, higher education in the study of 40.02 million. Among them, 424,200 are studying for doctoral degrees, 2,439,500 are studying for master's degrees, 30,315,300 are enrolled in general colleges and universities, 460,000 are enrolled in five-year colleges and universities, 317,500 are enrolled in post-secondary colleges and universities, and about 6,060,000 are enrolled in adult colleges and universities, self-study examinations, network education, and open education ****.

Almost every university has opened computer-related majors, computer science majors must learn the development of languages, languages to C, C++, JAVA, network technology, Python is mainly in the way of elective courses exist, Linux subjects in the University Department of Computer Science and Technology, Software Engineering, Computer Networks, Information Management and Information Systems did not set up a Linux major, most people are concentrated in the computer science and technology, software engineering, computer networks, information management and information systems. Most of the people are concentrated in the development field where the masters are working, and the competition is fierce.

Linux due to the scarcity of talent, fewer jobs, important positions, companies in the recruitment of difficult, in order to recruit professionals, had to reduce educational requirements, improve treatment. This is also the IT industry for the few positions that do not value education in skills, of course, large companies or engaged in technical management type of positions, education requirements are getting higher and higher.

Recommendation 5: easy to get started, can be quickly mastered

As an IT work engaged in, our ultimate goal is the CTO or architect position, as a qualified architect, development and Linux operation and maintenance are indispensable skills, first learn to develop and then learn the operation and maintenance, for the high degree of education and computer professionals, suitable to climb such a steep slope, for low For those who are highly educated and computer professionals, it is appropriate to climb such a steep slope, and for those who are less educated and switching careers, it is appropriate to climb such a gentle slope and make a smooth transition by first learning operations and then developing.

As we all know, development requires good English and logic skills, addition, subtraction, multiplication, division, or not, matrices, permutations, combinations, linear algebra, and statistics are indispensable. But Linux common commands about 200, more technical solution-oriented to hands-on, easy to remember to master.

We can understand the IT industry as a big supermarket, our goal is to want to enter this supermarket, do development is to go to the front door, many people, not easy to enter.

Doing Linux is from the back door, fewer people, easier to enter. Waiting to enter the IT industry after we can rely on their own advantages, inventory of their own resources, choose a good direction to further improve their own, I believe everyone will get the results they want.

Recommended reason 6: wide career path

Career path 1: Linux operation and maintenance - Linux senior operation and maintenance engineers - DBA - DBA expert - DBA master

Career path 2: Linux operation and maintenance - Linux senior operation and maintenance engineers - Linux cloud computing senior operation and maintenance engineers - website architect - CTO

Career Path 3: Linux O&M - Linux Senior O&M Engineer - Automation O&M Engineer - Automation Development Engineer (need to know Python)

Career Path 4: Linux O&M - Security O&M Engineer - Security O&M Management Post - Enterprise IT Security Consultant

Mastering the following skills can be done

If you want to work on Linux-related jobs, you need to master the following knowledge structure

k8s & Security

Summary: As long as there are servers in the company can not be separated from the Linux operation and maintenance, small to a few people in the company, large to Baidu, Tencent, Ali, drop, the United States group, the Bank of China, the Pacific Insurance and other large companies, the role of operation and maintenance in the IT department is irreplaceable. They guarantee the safe, stable, and reliable operation of servers, systems, databases, and cloud computing platforms, and are the heroes behind the scenes that deserve respect.
