Suddenly, I look back on the ten years I’ve been doing development. I’ve gained a lot in those ten years, technical skills, training, going abroad, big company experience, and a lot of good friends. But on second thought, I wasted at least five years in these ten years, which could have been enough for me to grow into an excellent programmer. Unfortunately, I missed it. Like many programmers, I could not find a way out in the confusion and confusion during these five years.

The road is always there, we just can’t see it!

I used to be driven by companies and technology. I didn’t choose technology, I was pushed into it. Think about how many people have thought deeply about and compared the types of careers and skills they want to pursue in the future. When I got out of coding, I started thinking about programming and the career of a programmer, and it turned out that there are a few things we all say that get us to where we are today.

Today, I will sort out a list of the most mainstream technology selection of Internet companies:

Read the source code

Programmers work with code every day. After years of basic education and professional training, most programmers can “write” code, or at least copy and modify code. However, can read the code is not in the majority, can read the code and really understand the source code of some big projects, very few. This also leads to a lot of errors in the way source code is viewed.

How to analyze the source code correctly?

Distributed architecture

As our business more and more and more important, monomer architectural patterns have been unable to corresponding large-scale application scenarios, and the system must not exist in a single point of failure cause the overall is not available, so only vertical or horizontal split business system, make them form a distributed architecture, the use of distributed architecture to eliminate redundant system of single point of failure, Thus improving the availability of the entire system. At the same time, the module reuse degree of distributed system is higher, faster, higher expansibility is an essential link of large projects.

1. In the right project and the right team, the benefits of adopting the microservice architecture will outweigh the costs. 2. There are many attractions to microservices architecture, but before you embrace microservices, you also need to recognize the challenges it presents. 3. You need to avoid microservices for the sake of microservices. 4. Introduction strategy of microservice architecture — For traditional enterprises, it is advisable to introduce some appropriate principles of microservice architecture to transform existing systems or create new microservice applications at the beginning, and gradually explore and accumulate experience of microservice architecture, rather than implement microservice architecture completely.

Performance optimization

We don’t just have to manage the project, we have to solve all the performance problems. Only by deeply studying the underlying principles of JVM, Mysql optimization and Tomcat tuning, can we achieve the effect of knowing what it is and why. In addition to performance optimization, it can also provide common ideas and consideration points for scheme selection, helping people to cultivate awareness, thinking and the ability to do various trade-offs in scheme selection.

Concurrent programming

It mainly cultivates programmers to deeply understand the operation principle of the bottom layer, and strengthens programmers’ logical thinking, so as to write efficient, safe and reliable multithreaded concurrent programs.

The development tools

A software project management tool that manages project builds, reports, and documentation with a short description of information. Designed to monitor continuous repetitive work, it aims to provide an open and easy-to-use software platform that enables continuous integration of software. Can effectively and quickly handle project versioning from very small to very large

The project of actual combat

If you want to be based on an Internet company and not be submerged in the Internet wave, it is necessary to develop practical exercises for the project, and it is also a measure of your own ability. How much amount is equal to how much return you get. How much can we know about the underlying principle and implementation principle of a seemingly simple project requirement map?

How to learn above these, have free material?

Students who are interested in Java technology, architecture technology, click to read the original text, learn together, discuss with each other.

Some friends have sorted out the knowledge system (source code, notes, PPT, learning video), welcome to get free.

This article is shared to programmers who like Java, like programming and dream of becoming an architect. I hope it can help you.

It doesn’t matter if you are not a Java programmer, help forward to more friends! thank you

Share a tip click to read the original article can also easily access to learning materials oh!!
