If we already have our Terraform and modules, do we have to split them up as separate Nuon components, or can we leave them as one?

QUESTION

If we already have our Terraform and modules, do we have to split them up as separate Nuon components, or can we leave them as one?

ANSWER

No requirement to split. Nuon is agnostic. You can keep a single root module as one component. Splitting is useful to make the component dependency graph visual and to speed up updates when only upstream pieces have changed — but there's no loss from keeping everything together. Action triggers (pre-deploy, post-deploy, post-fail) and troubleshooting actions all work at the component level regardless of how many components you have, so a single component gets everything.
