With the need for more flexible backend solutions, NoSQL databases have gained enormous popularity. They power applications that require a more flexible data structure than traditional structured databases can provide.
Two of the most popular market leaders for NoSQL databases are MongoDB and DynamoDB, which provide robust feature-rich NoSQL database platforms.
In this article, we will compare these two databases to help you choose the right database for your project.

What is MongoDB?
MongoDB is a general-purpose, document-based distributed NoSQL database. It offers:
- A free and production-ready community version
- An enterprise edition with direct support from MongoDB Inc.
MongoDB Atlas is the cloud database. Unlike other offerings, MongoDB Atlas is cloud-agnostic and can be deployed on any major cloud provider with guaranteed availability and scalability while conforming to all the compliance and security standards. It also provides a free MongoDB cluster that can be used for application development.
