    Sign in to your AWS account and navigate to the Amazon DocumentDB section.

  2. Choose the Cluster Configuration:

  3. Select the instance size based on your anticipated workload.

  4. Choose a VPC, subnets, and security groups that your cluster will use.

  5. Set Up the Cluster Identifier:
    Provide a unique name for your cluster to help you easily identify it later.

  6. Select the Instance Type:
    Choose from the range of instance types offered by Amazon DocumentDB based on your performance needs.

  7. Storage Configuration:
    Decide on the required storage and enable auto-scaling for optimal performance.

  8. Configure Backup and Maintenance Options:
    Customize your backup window and maintenance preferences to suit your business needs.

  9. Review and Create Cluster:
    Double-check all configurations and create the cluster. This will take a few minutes to complete.

  10. Connect to the Cluster:
    Use your application to connect to the DocumentDB cluster using connection URI.

Connecting to Amazon DocumentDB

To connect your application to Amazon DocumentDB, you can make use of the MongoDB drivers available in various programming languages. This allows you to utilize familiar MongoDB API calls, making the transition smooth.

Here are some example connection strings for Python and Node.js:

  • Python example using PyMongo:
    python
    from pymongo import MongoClient

    uri = “mongodb://username:password@docdb-cluster-url:27017/?ssl=true&replicaSet=rs0&readPreference=secondaryPreferred”
    client = MongoClient(uri)
    db = client[‘your_database’]

  • Node.js example using Mongoose:
    javascript
    const mongoose = require(‘mongoose’);

    const uri = “mongodb://username:password@docdb-cluster-url:27017/your_database?ssl=true&replicaSet=rs0&readPreference=secondaryPreferred”;

    mongoose.connect(uri, {
    useNewUrlParser: true,
    useUnifiedTopology: true
    });
