What configuration is needed to ensure that Web-based applications send HTTPS requests to specific databases in SAP HANA?

To enable Web-based applications to securely send HTTPS requests to specific databases in SAP HANA, configuring an SAP Web Dispatcher for each tenant database is the optimal solution. The Web Dispatcher serves as a reverse proxy and load balancer that allows clients to interact with different database instances in a secure manner over HTTPS.

By implementing the Web Dispatcher, you can effectively route incoming HTTPS requests to the appropriate tenant database based on the defined rules or configurations. This setup not only secures the data in transit through encryption but also provides an added layer of control over which applications can access particular databases. It fundamentally enables better scalability and manageability of database connections, ensuring that requests are directed correctly without exposing the databases directly to client requests.

The alternative configurations mentioned would not provide the same level of functionality in this specific scenario. While a load balancer could distribute traffic, it may not adequately facilitate the secure routing of HTTPS requests specifically tailored for database connections. Similarly, configuring alias hostnames or setting up firewalls alone would not address the specifics of managing HTTPS requests effectively for distinct tenant databases within the HANA environment.
