I'm developing an app that contains next.js as a frontend and separated backend server running on express. I'm wondering about production deploy and costs, I did some research but I'm not sure what's the best way to do it.

My folder structure is following. I have separated packages.json on the frontend and separated on the backend. Two apps also run on different port. Also I'm doing SSR on the frontend.

Next.js already includes a server like express. API Routes allow you to build a backend deployed along with the rest of the next application.

API Routes live in the /pages/api folder.
