# Connect to Amazon DocumentDB
<a name="connect-docdb"></a>

Amazon DocumentDB provides multiple connection options, including programmatic connections using MongoDB drivers, connecting from outside a VPC through SSH tunneling or Amazon VPN, and popular tools like Studio 3T and DataGrip. The service supports replica set connections for high availability. For analytics and reporting, you can connect using JDBC or ODBC drivers. EC2 instances in the same VPC can connect directly to DocumentDB clusters. All connections require TLS and proper Amazon credentials/authentication.
