Managing VPC Connections

You can use a VPC connection to connect a cloud data source to DLV for data display on screens.

DLV supports the following data sources connected through VPC:

  • DWS
  • MapReduce Service ClickHouse
  • RDS for MySQL
  • RDS for GaussDB
  • RDS for PostgreSQL
  • GeminiDB for InfluxDB (RDS for GaussDB for Influx)
  • RDS for SQL Server
  • Cloud Search Service
  • Custom data sources on ECSs

Prerequisites

  • Only users with the DLV FullAccess and VPCEndpoint Administrator permissions or users with the Tenant Administrator permission can create or delete VPC connections.

    The Tenant Administrator permission has all cloud service administrator permissions except the IAM management permission. For security purposes, you are not advised to grant this permission to IAM users. Exercise caution when performing this operation.

  • The data source instance to be connected has been created.
  • The corresponding security group rules have been configured.

Create VPC Connections

  1. Log in to the DLV console.
  2. Choose Control Center > VPC Connection Management. Click Create VPC Connection.
