Document databases like Amazon DocumentDB and MongoDB store data in documents, whereas SQL databases store data in tables. This fundamental difference leads to some notable variations between the two.

One key difference is the way data is structured. Document databases have a flexible data structure, whereas SQL databases have a rigid one. This means that document databases can store data of varying sizes and structures, making them a good fit for storing complex data.

Document databases are also very performant for handling complex queries, whereas SQL databases can struggle with complex queries. This is because document databases use a JSON-like query language, which is designed for querying semi-structured data.

Another difference is the ease of use. Document databases are often easier to use for developers who are not familiar with SQL, whereas SQL databases can be harder to use for those who are not familiar with the language.

Here's a comparison of document databases and SQL databases in a table:

Overall, the choice between a document database and a SQL database depends on the specific needs of your project. If you need to store complex data and query it efficiently, a document database like Amazon DocumentDB may be the better choice.

Amazon DocumentDB offers compatibility with MongoDB, so it supports the same APIs that MongoDB does. However, the similarities largely end there.

One of the key differences is that DocumentDB is a fully managed document database service, whereas MongoDB is an open-source document database. This means that DocumentDB handles tasks like scaling and maintenance for you, while MongoDB requires more manual effort.

DocumentDB has explicit proficiencies that are compatible with MongoDB. Some of these include the ability to use existing MongoDB APIs for querying documents, as well as existing MongoDB drivers and tools.

Here are some of the specific capabilities that DocumentDB has that are compatible with MongoDB:

In contrast, MongoDB is known for its high levels of flexibility and scalability, which can be beneficial for certain use cases. However, this also means that MongoDB requires more manual effort to set up and maintain.

Ultimately, the choice between DocumentDB and MongoDB will depend on your specific needs and preferences. If you value the convenience of a fully managed service and don't mind giving up some flexibility, DocumentDB may be the better choice.

DocumentDB doesn't have a public endpoint by default, which means it's not intended to be exposed to the internet. It's typically deployed on a private network within a VPC and accessed by applications running on the same VPC.

To access the DocumentDB cluster from an external Public IP, you'll need to create a Network Load Balancer (NLB) in front of the Read Replica. This is a good practice to separate public access and private access.

A Network Load Balancer can enable a public endpoint for the Read Replica, allowing you to access the database from anywhere.

You'll need to put the security group that you created earlier in the security group section of the NLB. This ensures that only authorized traffic can access the database.

To test your configurations, run a PowerShell command from the folder where you downloaded the "global-bundle.pem" file. Replace the NLB endpoint and username with your credentials.
