Overview

Scenarios

This best practice involves two tasks:

  • Create an RDS for MySQL instance.
  • Use DRS to establish a remote single-active DR relationship for the RDS for MySQL instance.

Prerequisites

  • You have registered with Huawei Cloud.
  • Your account balance is greater than or equal to $0 USD.

How Cross-Region DR Works

RDS for MySQL instances are deployed in the production and DR data centers. DRS replicates data from the production center to the DR center, keeping data synchronous between your primary instance and the DR instance.

Service List

  • Virtual Private Cloud (VPC)
  • Elastic IP (EIP)
  • Relational Database Service (RDS)
  • Data Replication Service (DRS)
