I’m a fan/user of Pulumi, but this doesn’t feel similar to me. In Pulumi you write code that describes infrastructure, separate from the application layer code you’re deploying.

This appears to be using application code to derive infrastructure config automatically. It’s a but like the https://www.shuttle.rs/ approach.

Edit: after taking a deeper look, a more accurate description might be that it allows you to embed application code within IAC.

Pulumi has both, they have something very similar to what is being offered here: https://www.pulumi.com/docs/tutorials/cloudfx/

I did not know that, I stand corrected!
