Overview

Updated on 2024-12-30 GMT+08:00

This practice describes how to install a MySQL database (community edition) on a Huawei Cloud ECS and create a TaurusDB instance, and use DRS to migrate data from MySQL to TaurusDB. With DRS, you can perform real-time migration tasks with minimal downtime.

Scenarios

  • With the rapid increase of enterprise workloads, traditional databases have poor scalability and require distributed reconstruction.
  • Building traditional databases requires purchasing and installing servers, systems, databases, and other software. Its O&M is expensive and difficult.
  • Traditional databases are poor in complex queries.
  • It is hard for traditional databases to smoothly migrate data with no downtime.

Prerequisites

  • You have created Huawei ID and completed real-name authentication.
  • Your account balance is at least $0 USD.

Solution Architecture

In this practice, the source database is an ECS-hosted MySQL instance and the destination database is a TaurusDB instance. Figure 1 shows the deployment architecture when the ECS-hosted MySQL and TaurusDB instances are in the same VPC.

If the ECS-hosted MySQL and TaurusDB instances are not in the same VPC, you need to configure a VPC peering connection between the two VPCs. For details about the deployment architecture, see Figure 2.

TaurusDB Advantages

  • Robust performance: TaurusDB decouples compute from storage and uses a "log as database" architecture and remote direct memory access (RDMA). It can deliver seven times the performance of open-source MySQL for certain service loads.
  • Elastic scaling: In addition to a primary node, you can add up to 15 read replicas for a DB instance within minutes. You can also scale up or down CPU and memory specifications for a DB instance as needed.
  • High reliability: DB instances can be deployed across AZs and there are three data copies under the shared distributed storage layer. A DB instance failover can be complete within seconds with a zero RPO.
  • High security: With shared distributed storage, TaurusDB ensures zero data loss and fault recovery within seconds. VPCs, security groups, SSL connections, and data encryption are used to strictly control secure access.
  • High compatibility: TaurusDB is fully compatible with MySQL. You can easily migrate your MySQL databases to TaurusDB without refactoring existing applications.
  • Mass storage: Based on Huawei-developed Data Function Virtualization (DFV) distributed storage, TaurusDB supports up to 128 TB of storage.

Service List

  • Virtual Private Cloud (VPC)
  • Elastic Cloud Server (ECS)
  • TaurusDB
  • Data Replication Service (DRS)

Notes on Usage
