Hi SWE @ Brainboard here,

Indeed, managing complexity is one of the most difficult part of making a graphical tools useful, and some architectures cannot inherently be represented only by a simple 2d graphic.

On the flip side, IAC can sometime be complicated to reason about without deep-diving in the source code and having deep knowledge about Terraform and every cloud provider.

We believe that there is a middle ground, where Brainboard helps engineers design and communicate about their architecture efficiently, are able to manually edit the generated Terraform files, while avoiding the churn of constantly redrawing their documentation graphics.

The best answer is really to try it out. Let's do it and see if it works or not. By the way we are implementing complex architectures (that will be available in the marketplace) and it just works as expected.
