Hi,
My comments may not be relevant to your question as I am not sure if your intention is to learn or use AWS HANA (if instance is HANA one) instance for production.
Some companies can not put their data on cloud. Or you can use AWS HANA developer edition for production.
Anyway, we use SLT for real time data replication to local HANA system. More info can be found here
