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.
Speaking of Alibaba architects, the gold content is not to mention, it is regarded as a 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, See how hard you work.
Today, the high-energy place 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 + first-line Internet enterprise interview questions)
The article is limited. I can only show some examples below for everyone to see. I can't describe them all. There is a complete pdf version for free sharing. If you need it, you can click here to see all the content of the document.

- How to optimize Tomcat?
- Memory tuning
- Garbage collection strategy tuning
- Shared session processing
- About the number of Tomcat sessions
- Monitor Tomcat's memory usage
- Tomcat complete process of a request
- Tomcat working mode?
- …
3.2 Distributed (Redis+mongoDB+MQ+Kafka+Nignx+ZK)
- Take Zookeeper as an example:
- What is ZooKeeper?
- What does ZooKeeper provide?
- Zookeeper file system
- Four types of znode
- Zookeeper notification mechanism
- What does Zookeeper do?
- zk's naming service (file system)
- zk configuration management (file system, notification mechanism)
- Zookeeper cluster management (file system, notification mechanism)
- Zookeeper distributed lock (file system, notification mechanism)
- The process of obtaining a distributed lock
- How does zookeeper ensure the sequential consistency of transactions?

3.3 Open source framework (Spring+SpringMVC+Mybatis)
Take SpringMVC as an example:
3.4 Microservice architecture (Dubbo+SpringBoot+SpringCloud)
SpringCloud as an example:
What is Spring Cloud?
What are the advantages of using Spring Cloud?
What does service registration and discovery mean? How to achieve Spring Cloud?
What is the significance of load balancing?
What is Hystrix? How does it achieve fault tolerance?
What is a Hystrix circuit breaker? Do we need it?
What is Netflix Feign? What are its advantages?
What is Spring Cloud Bus? Do we need it?
…
3.5 Performance optimization (Mysql optimization + JVM optimization + Tomcat optimization)
- Memory model and partition, what needs to be put in each area in detail?
- Partitions in the heap: Eden, survival (from + to), old age, their own characteristics.
- Object creation method, object memory allocation, object access location.
- What is SafePoint?
- The three collection methods of GC: the principles and characteristics of mark removal, mark sorting, and copying algorithms. Where are they used? If you are asked to optimize the collection method, what ideas do you have?
- What are the GC collectors? Features of CMS collector and G1 collector.
- When do Minor GC and Full GC happen respectively?
- Several processes for class loading?
- JVM memory is divided into several areas, what is the role of each area?
- How to judge whether an object is alive? (or how to judge GC objects)
- …
3.6 Interview questions for first-line Internet companies
to sum up
A programmer who does not 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 have paid?
