High energy! Alibaba produced the "Java Architecture Collection", everything from principle to actual combat

Preface

Architects are the career goals of many programmers. In career planning, becoming an architect is a long process. Of course, it also requires a complete and reliable plan, especially at the technical level. A higher level is required. This may require a complete route.

When it comes to the architects of Alibaba, the gold content is not to mention, it can be regarded as the benchmark in the industry. In fact, Alibaba is constantly training its own company personnel, so the growth in large factories is rapid. As for how to catch up with these big players, it is It depends on how hard you work.

Today, the place of high energy is here! The "Java Architecture Collection" produced by Alibaba will share with you, everything from principle to actual combat! This book of Java architecture mainly involves the following three aspects:

  • 1. The underlying principle (concurrent programming+JVM+Mysql+Tomcat+Spring family bucket+Zookeeper+middleware+Redis+Docker)
  • 2. Project actual combat (double 1.1 billion concurrent scene tuning actual combat + Xiaomi B2C mall actual combat + Meituan merchant distributed marketing system actual combat + SpringCloud Alibaba Meituan merchant system actual combat)
  • 3. Get the interview (Java based + distributed + open source framework + micro service architecture + performance optimization + interview questions for first-line Internet companies)

to sum up

A programmer who doesn't want an architect is not a good programmer.

The architect is first of all a good programmer, and secondly, the architect has to play the role of maintaining the architectural value of the application system architecture. Therefore, becoming an architect is not easy, depending on how much you paid?

Due to space limitations, I will not show them one by one. If you also want to be an architect, and those who want to have this Java Architecture Collection produced by Alibaba, pay attention: one-click three links (Like+Collection+Follow) Then directly add WeChat: mxh5261 to get it 100% free
