Connect Google app engine service with outside database server

[Ankit Dwivedi]

We are deploying the python flex application on the google app engine. And from the application, we are trying to connect a database server where IP whitelisting is important but as we find out GAE does not support Static IP and without static IP service IP change with every deployment. Please suggest what approach we can use in this case to connect with a database server.

Hello, 

You're right, App Engine itself does not provide a way to map static IP addresses to an application [1]. However you use Cloud Load Balancing and serverless NEGS to reserve a static IP address for your load balancer, which then directs traffic to your app [2][3].
