At present, the most popular in China is Alibaba’s Dubbo, which has been widely used by many Internet companies. In any case, the software was developed and open-source by some company to solve some of their own problems. Strictly speaking, they are not a complete set of solutions. Abroad, Spring Cloud is popular. Spring Cloud, developed by the Pivotal team, does not reinvent the wheel, but rather looks at various open source distributed service frameworks and integrates proven technologies into the components of the current Spring Cloud.
In this way, Spring Cloud builds a relatively complete enterprise-level implementation of microservices. More encouragingly, the Pivotal team has encapsulated these distributed frameworks with Spring Boot, cutting out the arcane details and providing developers with a distributed system development kit that is easy to understand, deploy, and maintain. After being introduced into China, Spring Cloud has gradually become the main scheme to build microservice system and become the mainstream of the market.
That’s why SpringCloud is so popular right now, and today we’ll learn about microservices from the following 20 aspects by comparing old and new circuit breakers, gateways, and more!
- Overview of distributed and microservices
- Technology base
- Service governance – Eureka
- Client Load Balancing – Ribbon
- Breaker one Hystrix
- New circuit breaker – Resilience4j
- Call an OpenFeign declaratively
- 1 Old API gateway one Zuul
- New gateway – Spring CloudGateway
- Configure a Spring Cloud Config
- Spring Cloud Sleuth full link tracing
- Microservices monitor with a Spring Boot Admin
- Generate a unique ID number mechanism
- Distributed database technology
- Distributed database transactions
- Distributed cache a Redis
- Chapter Distributed Session
- Distributed system permission verification
- Remote procedure call
- Microservice design and high concurrency practices
Below we will differentiation to tell that 20 part of contents, due to the content of the learning resources too much, the following show only a part of the directory contents (complete directory too much, can’t display all), at the same time in order not to affect the overall reading experience, the full version has been done for you, free access at the end of the article!

This learning resource systematically and thoroughly introduces the popular microservice architecture today, especially the implementation scheme of the mainstream Spring Cloud. However, the microservice architecture also has various defects of distributed system, so the common distributed technology is also introduced in the book. The contents of this book are easy to understand and the arrangement is simple. This book is a great reference for those interested in working with distributed and microservices.
