Application Configuration Service (commonly known as App Config Service) provides a Kubernetes-native experience to enable the runtime configuration of existing Spring applications that were previously leveraged by using Spring Cloud Config Server.
Spring Cloud Config Server was an essential component in microservices architectures for providing runtime configuration to Spring Boot applications.
Spring Cloud Config Server did this by enabling configuration management to be hosted in Git repositories on different branches and in directories that could be used to generate runtime configuration properties for applications.
Application Configuration Service is compatible with the existing Git repository configuration management approach. It filters runtime configuration for any application by using slices that produce secrets.
