Preface

With the rapid development of the Internet, technology is constantly being updated, and major companies are increasingly demanding programmers. In recent years, the microservice architecture has become more popular. Many first-tier Internet companies have also invested in the construction of the microservice architecture. The first-tier companies such as BAT have started the practice of microservices early. In the interviews of the major companies, the microservices are also very popular. It has become a compulsory exam question for interviews. It is the key to whether a Java programmer can win an offer to examine whether a programmer can master Spring Cloud technology.

There are benefits at the end of the article, don't miss it!

What is Spring Cloud microservice?

Microservice was first proposed by Martin Fowler and James Lewis in 2014. Microservice Architecture is a popular architectural idea in recent years, and its concept is not clearly pointed out. Martin Fowler, the chief scientist of ThoughtWorks, once explained this concept: The microservice architecture style is a method of developing a single application as a set of small services. Each application runs in its own process and is compatible with lightweight Mechanism (usually HTTP resource API) for communication. These services are built around business functions and can be deployed independently through a fully automated deployment mechanism. These services have minimal centralized management, can be written in different programming languages, and use different data storage technologies.

Features of microservices

Publish for specific services
Small impact, low risk, low cost, frequent releases
Fast delivery of demand and low-cost expansion
Elastic scaling
Adapt to the cloud environment

Write at the end

Microservice design is actually a very early design idea, because with the rise of virtualization technology, microservices can be implemented at low cost, so it has also become popular and rising.

The connotation of microservices is very deep, including automation, decentralization, independence, etc. The details cannot be summarized clearly in an article. When we are making technology selection or solutions, we should learn as much as possible about the technology. Combine the characteristics of our business with itself and origin to make better choices.

Welfare time

The learning document I shared today allowed me to master Spring Cloud proficiently, and also made me a senior Java engineer. This document can learn thoroughly and understand Spring Cloud microservices. If you still don’t understand microservices, use This document is very good to assist yourself from entry to proficiency.
