MongoDB
The database must be able to scale based on demand - DocumentDB can be scaled on demand just not automatically and with small downtime; There is no requirement for AUTO scaling. Also MangoDB not always can be migrated to DynamoDB in other hand both support JSON; So if you think about proper auto scaling its - B, you should use Dynamo DB with GW endpoint, but also you will have pain in the a** to migrate it from MongoDB to DynamoDB; if you need only to have functionality scale on demand even with provisioned IOPS its - D, and DocumentDB fully support MongoDB ir easy to migrate.
B is not correct because DynamoDB is not MongoDB-compatible. The legacy application expects a MongoDB API, so using DynamoDB would require significant application changes. Option D (Amazon DocumentDB with cluster endpoint) natively supports MongoDB, allows private subnet access, encrypted connections, and scales automatically.
