If it needs FIPS 140-2 compliance, it will need a FIPs validated S3 endpoint, using AWS Privatelink

  • Not without its constraints, host mappings (like local windows hosts files) are static in nature and typically require manual efforts to accommodate changes in your environment. In addition, in the unlikely event that an Amazon Availability Zone goes offline, multiple host mappings can be utilized pointing to the same bucket name with different interface endpoint IP’s.
