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.
