3. Scalability:
   • Allows you to scale your cluster by adding read replicas to handle increased read workloads.
4. Durability and Availability:
   • Provides high durability and availability by replicating data across multiple Availability Zones.
5. Security Features:
   • Offers encryption at rest and in transit, fine-grained access control, and integration with AWS Key Management Service (KMS).
6. Automated Backups and Snapshots:
   • Enables automated backups and manual snapshots for data protection and recovery.
7. Indexing and Querying:
   • Supports indexing and querying of JSON-like documents using the MongoDB query language.
8. Data Compression:
   • Uses a native wire protocol to compress data for efficient storage and retrieval.

Configuration Example:

Let's create a simple Amazon DocumentDB cluster using the AWS Management Console:

1. Login to AWS Console:

   • Navigate to the AWS Management Console.
2. Open DocumentDB Console:
   • Click on the "DocumentDB" service in the console.

8. Review and Create:
   • Review the cluster configuration and click "Create cluster."
9. Monitor Cluster Creation:
   • Monitor the cluster creation process in the DocumentDB console until the status becomes "Available."
10. Connect to Cluster:
    • Once the cluster is available, connect to it using a MongoDB-compatible query client or tool.
11. Load Data and Run Queries:
    • Load data into the DocumentDB cluster and run MongoDB queries using the MongoDB query language.
12. Scale Cluster (Optional):
    • Optionally, scale the cluster by adding read replicas to handle increased read workloads.
13. Backup and Restore (Optional):
