You can definitely avoid the hyperscalers, but unless your ops are very simple, you'll end up paying for it with the cost of managing your infra yourself. Think about resiliency for example. What happens if the DC you're in goes down? Have you got another DC to direct traffic at? Do you need that? These sorts of questions are the ones that being in "the cloud" makes simpler to answer. I'm of the opinion that not every app needs 99.99999% uptime and not every app needs to be in the cloud though, so godspeed to you should you continue with this approach. There's no technical reason why you can't dramatically scale from this point.
