A solutions architect is migrating a document management workload to AWS. The workload keeps 7 TiB of contract documents on a shared storage file system and tracks them on an external database. Most of the documents are stored and retrieved eventually for reference in the future. The application cannot be modified during the migration, and the storage solution must be highly available. Documents are retrieved and stored by web servers that run on Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group can have up to 12 instances. Which solution meets these requirements MOST cost-effectively?
