Before we head to how to get started with it, let's see the difference between Cosmos DB and MongoDB.

What Differs Between Cosmos DB and MongoDB?

Cosmos DB and MongoDB are both databases, but they have some key differences. So let's explore the difference between Cosmos DB and MongoDB in simple terms:

Technology and structure

Cosmos DB: It is a managed database service provided by Microsoft. This means they take care of the underlying infrastructure and maintenance for you. Azure Cosmos DB sample data supports multiple data models.

MongoDB: It is an open-source database software. One that you need to set up and manage yourself. MongoDB focuses primarily on the document data model. This is where you store data in JSON-like documents.


Cosmos DB: Microsoft Azure DocumentDB core offers a seamless global distribution and automatic scaling. This means your data can be spread across different regions worldwide. Moreover, as your application grows, Cosmos DB can automatically adjust. This is to handle more data and users.

MongoDB: While it can scale, you need to manage the scaling process yourself. Setting up and maintaining multiple MongoDB instances can be more challenging.

Backup and SLA

Cosmos DB: It offers automatic backups and provides a Service Level Agreement (SLA) that guarantees high availability and data durability.

MongoDB: You need to set up your backup strategy and ensure high availability by yourself.
