**Additional context**
The killer feature of the service is simplicity.
But in fact - it's easy to up and run just a very simple container with one open port.

If we need something a little more complicated, for example, connect to elasticache - this works the same way as ECS - setting up VPCs, networks, subnets, security groups and an expensive NAT gateway and etc.
So my terraform app runner project is actually +/- the same size as the ECS project.

This is so simple use case - connect to DB. Is there a way to simplify this?

**Feature request:**
What I expect is - select image, select the db to connect (maybe even from a drop down list) and boom - I throw money at the screen. Even for NAT gateway (but don't understand why I need this for the so simple service).
