Hi, my company is pursuing an solicitation that requires a end user facing accommodation reservation system. The RFP did not state any FedRAMP requirement but the Q&A mentions that the system must be in a "FedRAMP authorized environment". I'm trying to better understand if that means it just needs to run on FedRAMP certified infrastructure (AWS) or if it means we need an agency ATO?
