Network Connection

Configure secure network connections to your Nodegroup using public internet or private VPC endpoints.

Tacnode provides flexible network connectivity options to meet different security and performance requirements.

Connection Options

Public Network (Classic)

Best for: Development, testing, and scenarios requiring simple internet access

• Most straightforward connection method
• Security Note: Public access is disabled by default and requires manual activation
• Access configuration at: Nodegroup > Network

Private Network (VPC)

Best for: Production environments requiring enhanced security

• Each Nodegroup operates within an isolated VPC environment
• VPC access is enabled by default for security
• Uses cloud provider PrivateLink technology for secure connections
• Requires endpoint creation and approval process

VPC Endpoint Setup Process

Step 1: Create VPC Endpoint

The endpoint creation process varies by cloud provider. Detailed instructions are available for:

• AWS VPC Configuration

Step 2: Request Connection Approval

Important: Nodegroup endpoint services require manual approval for all connections.

After creating your endpoint, the connection will remain in “Pending” status until approved. Provide the following information for approval:

• Connection Name: Descriptive identifier for your endpoint
• Endpoint ID: Unique identifier from your cloud provider

Processing Time: Approval typically completes within 1-2 minutes

Step 3: Obtain Connection Details

Once approved, view your active endpoint connections and retrieve connection information at: Nodegroup > Network

Connecting to Your Nodegroup

Tacnode supports multiple PostgreSQL-compatible connection tools and drivers:

Command Line (psql)

psql -h <HOST> -p <PORT> -U <ACCOUNTNAME> -d postgres

JDBC Connection

jdbc:postgresql://<HOST>:<PORT>/postgres?user=<ACCOUNTNAME>&password=<PASSWORD>

Connection Parameters

Endpoint Cleanup

When to Remove Endpoints

Remove endpoint connections when:

• No longer needed for Nodegroup access
• Nodegroup is being decommissioned
• Cost optimization is required

Removal Process

1. Tacnode Platform: Remove the connection from Nodegroup network settings
2. Cloud Provider Console: Delete the corresponding endpoint to avoid ongoing charges
