Managing configuration with Spring Cloud Config
In a microservice architecture, managing configuration is crucial as applications scale and the number of services increases. Managing configuration locally through the application’s configuration presents significant problems, particularly regarding security, such as database passwords and redeployment when a property’s value changes. While simple and suitable for small projects, managing configurations locally can become cumbersome and error-prone as an application grows.
The configuration manager service provides a centralized approach to managing configurations across multiple applications and environments. This service externalizes configuration management, enabling dynamic updates and centralized control. Figure 7.13 illustrates the architecture of microservices, with the addition of a configuration management service.
