DynamoDB vs MongoDB

Amazon DynamoDB is a fully managed NoSQL database service. It provides fast and predictable performance with scalability. You can use Amazon DynamoDB to create a database table that can store and retrieve any amount of data, and serve any level of request traffic.

 MongoDB is an open-source document database and leading NoSQL database .MongoDB is an open-source, document database designed for less of development and scaling.

DynamoDB is for systems that need the ability to scale reading/writing throughput to very high levels, on demand. MongoDB is great way for easily storing and retrieving object graphs (represented as JSON) with great read/write performance and some RDBMS functionality like indexes and queries with predicates.


Let's now get into the main difference between DynamoDB and MongoDB:-














MongoDB, Inc.



Uses JSON only as a transport protocol

Data is not being stored "on-disk" in the JSON data format

Data is stored in BSON format (Binary JSON)

Supports up-to 100 levels of nesting

 APIs and other access methods




Proprietary protocol using JSON


Supported Programming Languages






Licensing and pricing models


With Amazon DynamoDB, you only pay for the throughput and storage you need.


MongoDB database server: Free Software Foundation's GNU AGPL. Commercial licenses are also available from MongoDB, Inc.

MongoDB supported drivers: Apache License.


Application Scenarios


 Ad Tech , IOT , Gaming


Internet of Things(Bosch, Silver Spring Networks),Mobile ,Content Management (eBay, Forbes)





Features of DynamoDB over MongoDB: -

1. Analytics

Extending the application of analytics to a database has not been as easy. Ideally, we would just want to send a request to the database and have it send back the result when ready. But every NoSQL database has failed in this aspect. MongoDB has major limitations when running map-reduce jobs.

On the other hand, DynamoDB integrates with Elastic Map Reduce and reduces the complexity of analyzing unstructured data. This is a BIG plus.

2. Ease of getting started

If you have an AWS account, getting started with DynamoDB is as simple as making a single API call! With other NoSQL solutions, the developer must have the right servers, installations and configurations.

With DynamoDB, they just need to concentrate on the application and let AWS handle the rest.

3. Security

In DynamoDB Authentication, use of latest cryptographic technique, ability to integrate with IAM (AWS Identity and access management).

MongoDB Enterprise Advance provides extensive support authentication, authorization, auditing and encryption


DynamoDB looks a lot like many other NoSQL solutions, but there are some significant design limitations in exchange for its zero maintenance and effortless scaling.

On the other hand spending less time on maintaining and configuring our MongoDB cluster, because that frees up our time to focus on actually building our product on development period.
