Question:
In a microservices architecture using Spring Boot, how would you handle configuration management across multiple environments (e.g., development, staging, production)? Can you explain how you would use Spring Cloud Config or other strategies to manage environment-specific configurations while ensuring security and scalability?

Answer:

„In addition to using application-{env}.yaml files like application-test.yaml or application-prod.yaml, we can utilize Spring Profiles to activate these configurations dynamically based on the environment. For example, we could set the active profile using the spring.profiles.active property.

However, for larger and more complex systems, where configuration must be shared across multiple microservices, I would recommend using Spring Cloud Config.

Here’s how I’d approach it:

• Use a Spring Cloud Config Server backed by a Git repository to store all environment-specific configurations. This allows version control and easy updates without redeploying services.
• Implement feature toggles and environment-specific properties to dynamically enable or disable certain features based on the environment.
