Question

What is the difference between the followings?

• Spring Cloud Config Server with Vault backend - http://cloud.spring.io/spring-cloud-static/Camden.SR4/#_spring_cloud_config_server

Answer 1

Spring Cloud Vault is more lightweight because it does not require to run a java server (Spring Cloud Config Server) as a frontend for Vault, your Spring Boot app connects directly to Vault.
