I agree everything on one box makes sense very early on. I'd add that you do want to put some time into designing your architecture so that it's easier to decouple, so you can iterate and separate services when you have a moment to do so, or you can scale when you absolutely have to. Spending a few hours early on thinking about the following, will save you days of headache. Eventually talk to a database on a different machine. Your web app is either stateless, or has an external session cache. You can have a process that is not your web app process, do "jobs." Etc.
