Yeah, definitely. We would like to have modes of operation where Restate puts its state only in S3. In that world, it could potentially run for short periods, and sleep when there's no work to do.

Cloud only has an early access free tier right now. We intend to make Cloud into a highly multitenant offering, which will make the cost of a user that isn't doing anything with their cluster effectively 0. In that world, we can do really cost effective consumption pricing for low-volume serverless use cases. Absolutely this requires trust, and some users will always want to self host, and we want to make that as easy and cost effective as possible. Its worth noting that we should be able to support client side encryption for journal entries, in time - in which case, you don't have to trust us nearly as much.
