First-party SaaS meaning things like RDS, DBaaS, queues, LBs etc? Most of that I would sort of put into a IaaS controlled PaaS, rather than true IaaS SaaS. Yes, these are generally higher on the trust spectrum as they don't involve additional vendors accessing/managing/storing data.

A major one I'm thinking of is BigQuery, also of course all the various db/queue solutions outside of your typical S3 clone as you mentioned. That would make sense viewing them as platforms though
