1 Introduction
In the world of Spring Cloud, distributed systems have gone through three stages: development, testing, and operation and maintenance. In the development stage, a centralized configuration method is usually adopted to uniformly manage all configuration files on one server. With the continuous expansion of the business system, each microservice module needs to configure its own attribute values. Therefore, a distributed configuration center is needed to solve this problem. Spring Cloud provides a distributed configuration center solution based on Netflix Eureka and Spring Cloud Config. This article mainly takes Eureka as an example for analysis.
Spring Cloud is a collection of frameworks that leverage the Spring Boot technology stack to simplify the development of distributed systems. Among them, the distributed configuration center is a service provided by Spring Cloud to solve configuration file management. In Spring Cloud, there is a sub-project called Spring Cloud Config to solve this problem. Spring Cloud Config can help applications load configuration data from remote Git or Subversion repositories and manage them centrally.
The main content of this article:
1. Introduce Spring Cloud distributed configuration center Eureka
2. Briefly understand the functional characteristics of Spring Cloud Eureka
3. Learn the basic usage of Eureka through Demo
4. In-depth study of Spring Cloud Eureka internal mechanism
5. Analyze Eureka configuration center with actual cases Advantages and disadvantages and improvement direction
5. Conclusion:
1. Eureka is an independent configuration center in Spring Cloud, which has functions such as service registration and discovery.
2. As an independent service, Eureka consumes less resources, and it also provides load balancing capabilities.
3. However, Eureka lacks functions such as authority management and auditing, so there may be certain obstacles to the company's IT security control.
