Overview

Description

You can use real-time synchronization of DRS to synchronize data from on-premises Oracle databases to Huawei Cloud DDM. Full+incremental synchronization can ensure that data is always in sync between the source Oracle database and the destination DDM instance.

Prerequisites

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

Service List

• Virtual Private Cloud (VPC)
• Distributed Database Middleware (DDM)
• Data Replication Service (DRS)
• Data Admin Service (DAS)

Deployment Architecture

In this example, the source database is an on-premises Oracle database, and the destination database is a Distributed Database Middleware (DDM) instance on Huawei Cloud. DRS synchronizes data from the source database to the destination database through the public network. For details about the deployment architecture, see Figure 1.
