What is the difference between DocumentDB and DynamoDB

Question

I’m working on a project and need to understand the differences between DocumentDB and DynamoDB. What should I know?

Answer 1

Understanding the differences is essential. Both are AWS NoSQL databases, but each fits different needs; here’s a quick comparison to help you choose the best one:

Feature	Amazon DocumentDB	Amazon DynamoDB
Database Type	Managed, MongoDB-compatible document DB	Managed key-value and document NoSQL DB
Data Model	Document-based (JSON)	Key-value & document-based
Use Case	Applications needing MongoDB compatibility	Low-latency, high-scale applications
Scalability	Horizontal read scaling, write scaling with replica sets	Fully serverless, automatically scales
Pricing	Based on instance size and I/O	Based on on-demand or provisioned throughput
