Is railway.app enough for my app? I know nothing about databases and scaling.

Let's say i'm building a banking app with nextjs and I have an endpoint /api/send-transaction This is POST endpoint and takes sender and recipient details with amount. The future for this endpoint is that it will be used by thousands of people per day. I know about severless and edge functions, but do I need them? Should I deploy to railway or aws with https://open-next.js.org/ ? What's the difference? What is cheaper and scales better for my use case? FYI: I know I'm naive to expect a straight forward answer to this.
