Origin of the matter
A while ago, Xiaotian saw some comments when he was scanning the headlines (Xiaotian suddenly felt that reading articles is not as interesting as reading comments)
Ali P6 is responsible for various coding and business logic implementation; Ali P7 is mainly the coding of the system architecture; P8 only has architecture ideas and frameworks!
The realization of business logic is certainly not easy, most of which is actually the realization of business logic!
In a large company like Ali, senior positions cannot be replaced. The turnover rate of lower-level positions should be very high. The salary of senior positions is indeed not proportional to the workload! Moreover, many of today's architecture systems are becoming more mature, and there are even more people who advance internally! The low-level developers are miserable! Who is Google in China, come and save the grassroots developers!

Big factory and small factory, only with ability can there be pomp
Alibaba, Bytedance, Tencent and other big factories are places that many programmers dream of. Those programmers who have already entered the big factories do not have the above ideas. They feel that since they have entered the big factories, the salary is not low, and they are a bit tired. Yes, but there are some very capable programmers who don't want to go to these big factories.
In other words, people in the "city" don't necessarily want to come out, and people outside the "city" don't necessarily want to go in. This is nothing more than the programmer's own belief that the layer of gold plated by the big factory is not important to him?
There are also many programmers who want to work in a foreign company. They think that the state of a foreign company is what they want, with less living and more money.
But, have you thought about it? What are the factors that really determine where you go? Undoubtedly, it is technical ability.
Whether it is a small factory or a large factory, or even a foreign company, ability is important everywhere. Small factories can also make millions of annual salaries, even easier than large factories. The important thing is that your technical ability must be outstanding.
What technical capabilities should be mastered
Here, Xiaotian directly gives a general direction. Through the comments in the front of the article, you can see that there is no improvement by pure technology. Those big guys who occupy high positions in Ali must have the ability to think about architecture and frame layout.
Note: All the following complete PDF documents of the core technical knowledge can be obtained for free by private messaging [Interview] in the background!
What are the architecture-related technologies?
1. Open source framework
Framework-related technologies such as Mybatis, Spring, and SpringMVC
2. JVM tuning
3. Mysql+concurrent programming+Netty+Linux+Tomcat
4. High concurrency and high performance
- MongoDB
- Redis
- Zookeeper
- Nginx
- Message middleware, etc.
5. Microservice series
Xiaotian won't talk about other technologies. If Java programmers can put the above technologies into the bag, it is not so important to you.
All in all, technical ability is the stepping stone to high salaries.
At last
I have compiled the PDFs of all the above core technical knowledge here, and also collected a set of the latest interview materials from major factories, as well as system interview questions. Friends who need help forward the article, backstage private message [Interview] to receive it for free!
