Until your (to extend your example) container orchestration is complex enough that that too requires faster/less permissioned iteration than infrastructure-as-code provides, in which case you need to reimplement the paid service locally. Hopefully then the paid service is open source or has some good-enough-for-your-needs analog like this.
FWIW, while the above sort of recommends kubernetes-everywhere, I'm happy to make a bet on a service like AWS Fargate because I _don't_ think I need to iterate on container orchestration much (as an application developer). Something like DynamoDB, by contrast, seems quite treacherous to build atop, given how closely an application's code is likely to be tied to its primary database.
