I built a full-stack app, how should I host it? (self.programming)

So basically I built a backend with some working endpoint and I built a React Frontend. I can run both things locally and I hosted the page on Cloudflare pages which is working. But now I’m wondering if that’s a good idea?

I have never done this before and I’m wondering if it’s secure enough to host the backend on some server and allow a CORS header to let the Frontend generate requests?

The alternative would be to host Frontend and backend on a VPS and then route my domain that I bought on Cloudflare there, but then I’m thinking that in case my Frontend is insecure somehow the whole instance would be compromised, no?

I hope this is the right platform to ask as I’m pretty new here.

That’s an interesting perspective. I am pretty paranoid and I run the backend API in docker from a non-root user. I am pretty paranoid but kinda clueless doing all of this myself, I did use an ssh key that requires a yubikey to login to the VPS and I don’t store any secrets on the VPS it‘s all managed via GitLab.

I’m just getting started, so there’s not even a DB currently, not yet needed. I would want to run everything over k8s eventually, and was considering hosting gitlab myself for the experience and because I can’t afford paying for the CI/CD stuff.

Does it make sense to run everything on a separate instance from a security perspective? I’m already having nightmares from thinking about the networking between all of that :D

There's definitely security advantages to running things across multiple instances: if one gets hacked, the others are unaffected.

The networking should be pretty simple for what you're doing. A few things just change to like 127.0.0.1 to something like 172.31.X.X or whatever IPs your VPC ends up using.

It looks like you're doing very well, I've seen big companies with less security than that.
