After many hours of research and self-studies I found a way to connect my local HANA Studio
to the HANA Server on AWS.
1.) Start your Instances on AWS.
2.) Go to the AWS Dashboard and click on INSTANCES > Instances to list all running instances.
3.) Choose the SAP HANA Server and look at the Description tab.
4.) Remember the long name behind Security groups.
5.) Click on NETWORK&SECURITY > Security Groups.
6.) Choose the line with that long name from step 4.
Click on the Inbound Tab.
7.) Create a new “Custom TCP rule” with Port range = 30015 and Source 0.0.0.0/0.
Add Rule and Apply Rule Changes.
