Personally I'd make sure the various services were at least deployable as Docker containers. That way there's a lot of flexibility in switching providers, and makes it easier to deploy on prem later if/when you need to. As for which platform? IMO the most important factor is which platforms the developer(s) are most comfortable/familiar with. The last thing a new SaaS startup needs is to waste time while the engineers figure out a new platform they've never used... Doesn't really matter how easy or cheap it is to deploy if there's no product ready to deploy ;)
