1. Adapt to the scene
The four configuration centers of Spring Cloud Config, Apollo, Nacos, and Archaius differ in their functions and usage scenarios.
1.Spring Cloud Config
Spring Cloud Config is an external configuration center for distributed systems officially provided by Spring Cloud. It provides server and client support, can centrally manage the configurations of different environments and different clusters, and supports dynamically refreshing configurations.
2.Nacos
Nacos is an easy-to-use, powerful configuration and service discovery platform dedicated to discovering, configuring and managing microservices. Nacos provides a simple and easy-to-use feature set to help realize dynamic service discovery, service configuration management, service metadata and traffic management, making it easier to build, deliver and manage microservice platforms.
3.Apollo
Apollo is an open source configuration management center developed by Ctrip's framework department. It can centrally manage the configuration of different application environments and different clusters. After the configuration is modified, it can be pushed to the application end in real time, and it has standardized permissions, process management and other features.
4.Archaius
Archaius is a dynamic configuration library that assumes that in distributed systems, configurations are dynamic and change frequently. Archaius uses network broadcasts to propagate configuration changes so that the configuration can take effect immediately after the application is restarted.
To sum up, choosing a suitable configuration center needs to be determined based on specific project requirements and architecture, and needs to be evaluated and selected based on the actual situation.
2. Their respective advantages and disadvantages
1.Spring Cloud Config
Advantages: Spring Cloud Config provides centralized configuration management for microservices, supports Git-based distributed configuration centers, and can be used with Spring Cloud to provide the function of dynamically refreshing configurations.
Disadvantages: The Spring Cloud ecosystem needs to be integrated, and Spring Cloud's starter dependencies need to be integrated on the client side.
2.Apollo
Advantages: Centrally manages the configurations of different environments and different clusters. After configuration modifications, it can be pushed to the application end in real time. It has complete permissions, process governance and other features, and is suitable for microservice configuration management scenarios. Friendly interface and easy to use.
Disadvantages: It needs to be integrated into the Apollo client, and a separate configuration management platform needs to be maintained.
3.Nacos
Pros: Nacos is dedicated to helping you discover, configure and manage microservices. Nacos provides a simple and easy-to-use feature set to help you realize dynamic service discovery, service configuration management, service and traffic management. Nacos helps you build, deliver and manage microservices platforms more agilely and easily. Nacos is a service infrastructure that builds "service"-centered modern application architecture (such as microservice paradigm, cloud native paradigm).
Cons: Not explicitly mentioned yet.
4.Archaius
Advantages: Archaius can automatically update configurations based on dynamic changes in configuration files, supports multiple configuration methods, and provides a rich API for operating configurations.
Disadvantages: It needs to be integrated into the application, and it may be difficult to integrate for some large projects.
In general, these four configuration centers have their own advantages and disadvantages. Which configuration center to choose depends on the specific application scenarios and needs.
