Here is an example connection string of a Cloud database that is hosted in the AWS region `us-east-1` and listens on port 16379: `redis-16379.c283.us-east-1-4.ec2.cloud.redislabs.com:16379`. The connection string has the format `host:port`. You must also copy and paste the username and password of your Cloud database and then either pass the credentials to your client or use the [AUTH command](https://redis.io/docs/latest/commands/auth) after the connection is established."
