Confusion over - SAP ECC OnPremise and AWS SAP HANA Integration

[former_member184871]

Hello Community,

I have a small requirement - where I need to connect SAP ECC with SAP HANA which is hosted on AWS. Considering the same I am not able to figure out what network connection / VPN / Web dispatcher I need to use if  I need to connect on-premise ECC to  AWS SAP HANA.

It would be great if anyone can point to some documents.

Awaiting response.

Regards

Hello Kumar,

your question yields no simple answer. I'll try to provide some possibilities:

- VPN tunnel : you need to configure a IPSec tunnel from your local site to your AWS VPC where the HANA DB is deployed. For that you need a router/firewall onsite which supports IPSec properly. Take in account that you'll be limited by your internet connection bandwidth.

Adding a Hardware Virtual Private Gateway to Your VPC - Amazon Virtual Private Cloud

- DirectConnect : this is a point-to-point connection from your premises to your AWS VPC. It's kinda expensive, but it has a lower latency than the VPN tunnel.

AWS Direct Connect - Private Network Connection to the AWS Cloud

Hope this answer your doubts. Let me know.
