In my opinion, if you don’t have a viable PaaS available, then this model does a very good job of reducing a system’s overall complexity. Having a single-service-per-host model is significantly easier to reason about and can help reduce complexity. If you can’t embrace this model yet, I won’t say microservices aren’t for you. But I would suggest that you look to move toward this model over time as a way of reducing the complexity that a microservice architecture can bring.
