Ask HN: As a solo/micropreneur, what infrastructure are you using?

In these days of Kubernetes and microservices everywhere I am using a monolith in a single server in which I have also the database (Just use S3 for object storage) (servers are pretty powerful nowadays)

I don't have scale and won't have it short-term, but I can't avoid feeling overwhelmed by what I read around here.

What is your real life not so cutting edge infrastructure?
