This document describes the network of TencentDB for PostgreSQL. TencentDB for PostgreSQL offers the network management feature to protect your instance security and provide service to internal and external businesses efficiently and freely.
There are two types of TencentDB network environments: VPC and classic network.
Currently, resources cannot be created in the classic network.
|Interconnection rule||Interconnection in the same region||Interconnection between subnets in the same VPC in the same region|
|Security control||Security group||Security group|
Tencent Cloud services can be accessed over both the public and private networks.
Security groups that currently support public network access are available only in the Guangzhou, Shanghai, Beijing, and Chengdu regions. Instances in other regions may be attacked if the public network access is enabled. We do not recommend that you enable public network access for instances in production environment. If you need to enable public network access, security group rules must be configured.
You can configure one or two networks for each TencentDB for PostgreSQL instance.
In scenarios where the instance supports two networks:
You can add, delete, and change networks in the TencentDB for PostgreSQL console. For more information, see Modifying Network.
