    Hi, I tried your spring-cloud-aws-example and I have two questions, can you answer me?
    1. Your sample is said to use Spring Cloud for AWS, but I can’t find any jar about Spring Cloud for AWS, I think you only use AWS SDK, right?
    2. I am running your sample on Mac, I can’t view in Safari what you said, do you know why?
