Introduction

Connecting to Amazon Web Services (AWS) DocumentDB can be a complex process, especially when you're working with a bastion host and a tunnel setup. In this article, we'll explore the correct connection type for DocumentDB and provide a step-by-step guide on how to establish a secure connection.

Understanding DocumentDB Connection Types

AWS DocumentDB is a fast, scalable, and fully managed document database service that supports popular document-oriented data models, such as MongoDB. When connecting to DocumentDB, you have two primary connection types to choose from: MongoDB and DocumentDB.

MongoDB Connection Type

The MongoDB connection type allows you to connect to DocumentDB using the MongoDB driver and protocol. This connection type is ideal for applications that are already using MongoDB and want to take advantage of DocumentDB's scalability and performance.

Pros of MongoDB Connection Type:

Familiar MongoDB API: If your application is already using MongoDB, you can use the same API to connect to DocumentDB.
Easy migration: You can easily migrate your MongoDB application to DocumentDB without significant changes to your code.

Cons of MongoDB Connection Type:

Limited support for DocumentDB features: The MongoDB connection type may not support all DocumentDB features, such as global tables and document-level encryption.
Security concerns: If you're using a MongoDB connection type, you may be exposing your application to security risks, such as unauthorized access to your database.

DocumentDB Connection Type

The DocumentDB connection type allows you to connect to DocumentDB using the DocumentDB driver and protocol. This connection type is ideal for applications that require advanced features, such as global tables and document-level encryption.

Pros of DocumentDB Connection Type:

Full support for DocumentDB features: The DocumentDB connection type supports all DocumentDB features, including global tables and document-level encryption.
Improved security: The DocumentDB connection type provides improved security features, such as document-level encryption and access control.

Cons of DocumentDB Connection Type:

Steeper learning curve: The DocumentDB connection type requires a deeper understanding of DocumentDB's API and features.
Additional setup required: You may need to set up additional infrastructure, such as a DocumentDB cluster, to use the DocumentDB connection type.

Establishing a Secure Connection to DocumentDB

To establish a secure connection to DocumentDB, you'll need to follow these steps:

Step 1: Create a DocumentDB Cluster

Create a DocumentDB cluster in the AWS Management Console. This will provide you with a unique endpoint and credentials to connect to your DocumentDB instance.

Step 2: Configure Your Bastion Host

Configure your bastion host to allow incoming SSH connections. You can do this by adding a rule to your bastion host's security group to allow incoming SSH connections from your IP address.

Step 3: Create a Tunnel

Create a tunnel using the ssh command to connect to your bastion host and forward traffic to your DocumentDB instance. You can use the following command to create a tunnel:

sudo ssh -o StrictHostKeyChecking=no -i "mongo-key-pair.pem" -L 27017:documentdb-instance.abc123.mongodb-studio.us-east-1.amazonaws.com:27017 o

This command creates a tunnel from your local machine to your DocumentDB instance, using the mongo-key-pair.pem key pair to authenticate.

Step 4: Connect to DocumentDB

Once you've created the tunnel, you can connect to DocumentDB using the mongo command. You can use the following command to connect to DocumentDB:

mongo --host documentdb-instance.abc123.mongodb-studio.us-east-1.amazonaws.com --port 27017

This command connects to your DocumentDB instance using the tunnel you created in the previous step.

Conclusion

In this article, we've explored the correct connection type for DocumentDB and provided a step-by-step guide on how to establish a secure connection. Whether you choose the MongoDB connection type or the DocumentDB connection type, make sure to follow best practices for security and scalability to ensure a successful connection to your DocumentDB instance.
