**To create a DB instance**

This example launches a new DB instance::

    aws rds create-db-instance \
    --allocated-storage 20 --db-instance-class db.m1.small \
    --db-instance-identifier test-instance --engine mysql \
    --enable-cloudwatch-logs-exports '["audit","error","general","slowquery"]' \
    --master-username master --master-user-password secret99

Output::
