The starting point of the protagonist of this inspirational story is to drive screws in the factory of Flextronics.
Change
He quit school very early. When he left the society, he had no education or skills, so he could only go to the factory to make screws. He has been driving screws in Flextronics' factory for many years. When he was close to 30 years old, his brother told him: You can't do this kind of work all the time. There is no promotion, it's just a repetitive job. You are almost 30 now, what should you do when you are too old to work? He listened to it, so he wanted to learn a professional technique. It just so happened that his brother did a very good job as a network engineer at H3C. Then I suggested that he can do this kind of work, and it will definitely be much better than him screwing in the future.
Now that he has something he wants to learn, how can he learn and enter the industry? First of all, his brother must have his connections. After all these years, he can be referred for interviews, but you know, any company will not recruit someone who can't do anything just because of employee relations. Therefore, he needs to learn something in advance and be able to do some basic work, and then his brother will recommend him. So through his brother's introduction to us to learn network technology.
study
How did he learn it? Of course, learn the most basic concepts first, such as what is an IP address in the basics of the network, and what is the OSI seven-layer model. After learning these most basic concepts, he will have a basic understanding of the entire network technology.
Next, he will get to know these common network devices, and what are these switches, routers, firewalls, and wireless AC+AP used for. In the home network for life, a small router of 100 yuan can solve all problems, but in the enterprise network for work, it is a professional network formed by many devices. So he will understand the functions of different network devices, how they cooperate and connect, so that he will have a structural understanding of a small enterprise network.
Then he began to understand the functions implemented by each device, learn how to configure these devices, and debug to realize the functions it should realize. He first learned how to configure VLAN on this switch, how to configure static routing on that router, and other independent knowledge points. After learning the individual knowledge points, he will be able to do small experiments. In this way, he has both theory and practice. ability. In the end, he will put all the individual knowledge points together to make a comprehensive technical realization, and he will be able to combine them when he knows the relationship between so many knowledge points he has learned.
Advanced
In the last step, he has an overall awareness of data flow. In the process of setting up the entire network, he will consider how the data goes from the computer to the Internet step by step, and then decide what configuration he should make on each device. During the whole process, he clarified the principle of communication and had the ability to troubleshoot. Because he knows how the data is connected, if he finds that the network is unavailable or stuck, he will have some troubleshooting ideas. What we are talking about here is the small and medium-sized enterprise network, which is to build it with a few devices. It can be understood as HCIA (Huawei Certified Engineer level). After getting this set of things solid, he can learn more complex network architectures.
If he goes to a professional position related to network technology and only knows this small and medium-sized network structure, it is definitely not enough. So he went to learn more professional network technology: high reliability, security, and network security-related firewalls, WAF, bastion hosts, intrusion detection systems, and access systems. With the foundation of digital communication, he is also at ease when learning these safety equipment. Now the network technology has been iterating and updating, just like IPv4 and IPv6, so he took the initiative to learn new network-related technologies such as IPv6 and Vxlan. Regarding his route of learning network technology, there is a complete set of study outlines. Friends who need it can directly like + follow and private message (learn) to get it!
Work
Then he went to work and successfully entered the H3C agent through his brother's referral. The previous study has given him enough technical accumulation, and only with such a foundation can he get started with network work better. When the leader gives him a task, he knows exactly what to do. After going to work, he quickly started to work and grew very quickly in charge of various corporate networks. However, the rapid growth of his ability did not match the cheap salary of the agent. Even if the technology of the agent is top-notch The monthly salary can barely reach tens of thousands.
opportunity
There is such a sentence in "The Fantastic Journey of the Shepherd Boy": When you make up your mind to do something, the whole world will help you! When he was ready to change jobs after years of study and work, Tencent just set up a data center in Changsha and needed a group of technicians to guarantee the network system of the data center. With a bachelor's degree, he successfully moved to Tencent's data center, which is now Tencent Yunqi. The higher salary here makes him very satisfied, and the more cutting-edge technology allows him to continue to grow. Sometimes I really think, is his enthusiasm for learning a result of his unwillingness to resign himself to the status quo, or does he really like network technology? Anyway, he has been at Tencent Yunqi until now, and this work experience and technical experience make it a smooth path for him to seek further development. Now he can not only solve various technical problems, but also has some cutting-edge network technologies at his fingertips.
story
The most important thing about a story is the beginning. The opportunity for him to start is that he learned about the career of a network engineer from his brother. Otherwise, in this life, he might find a "factory flower" to marry until he is old. How can he be in Tencent Yunqi in Changsha now? With the same high salary as Beijing, Shanghai, Guangzhou and Shenzhen without having to work overtime, the most important thing is that his self-learning ability has allowed him to keep adding value, and the future can be expected.
To sum it up: I have no education, screwed until I was close to 30 years old, learned about the network engineer industry through my brother, and then introduced it to an institution for training and learning. After I finished my studies, I successfully entered the H3C agent. After accumulating 2 years of work experience as an agent, it happened that Tencent Yunqi needed talents for its landing in Changsha, and then successfully switched jobs and worked until now.
at last
When the teacher chatted with me about him, he said that he had an interesting point, that is, he liked to engage in technology very much. I smiled and said that I might have grasped the straw. The teacher immediately refuted me, saying that he was not trying to save lives, but really liked to engage in technology. Then he told me an interesting story. When he first started working as an Internet worker, he got drunk once and dragged others to chat about technology: he said that he had learned everything he had learned back then. We talked about how OSPF is used, what happened to ARP, and so on for an hour.
Seeing this, you will think that he is a person who is born to engage in technology, or a person with strong learning ability. In fact, on the contrary, he had poor comprehension ability during the training, and it took him a long time to understand what the teacher told him. Even so, when he encounters technologies he doesn't understand, he will have the cheek to figure it out. He is not naturally suitable for technology, he really likes it.
