They're not quite identical
@tas but Google Cloud Run is the analogous GCP solution. I'm not sure what the setup burden is for it nor what the specifics are for running it with prefect so perhaps some others can chime in if they've experience with that.
In general the setup burden is lowered significantly by using
Prefect Cloud (which is free 😄), which takes care of the database, API, caching, and UI layers, leaving you to set up only your execution environments and Agent.
