If you have the skills, and the bottom line is still positive (include opportunity costs and personnel costs, ease of getting SOC2 / ISO certification if that's relevant to you, ease of scaling up and down), then you should go for other solutions.

I advice CEOs of SMEs on this, and I can tell you that the main concern they have is availability of people to build and maintain the systems. Because cloud / k8s is more popular these days, that's what they go for. If we could reliably find smart system operators that will happily maintain a couple of racks of servers for years, it would be a more viable option.
