DocumentDB is a fully managed document database that’s compatible with MongoDB. If a team runs MongoDB workloads and wants them managed on AWS, DocumentDB is the fit.
The tell
Watch for the word MongoDB or “document database with JSON-like documents.” DocumentDB runs MongoDB-compatible workloads without you managing servers. It’s distinct from DynamoDB (AWS-native key-value/document) — DocumentDB specifically targets MongoDB compatibility.
