Service availability

99.95%

Requires setting up the primary/standby relationship and HA environment for ensuring the availability.

Data durability

99.9999999%

Requires self-guarantee, primary/standby relationship setup, and RAID setup.

System security

• Anti-Distributed denial of service (DDoS) attack is supported, helping you repair various database security vulnerabilities in a timely manner.
• Supports log auditing.

• Requires procurement of expensive devices and software, as well as manual detection and fix of security vulnerabilities.
• Requires procurement of an audit system.

Database backup

• Supports automated backup and allows configuration of backup policies based on service operating period.
• Supports manually, physically backing up data at any time and increases backup efficiency by 3 times.
• Backup files are automatically uploaded to Object Storage Service (OBS) for storage.

• Requires self-setup and maintenance.
• The open-source version supports only logical backup, resulting in low backup efficiency.

Monitoring and alarm reporting

Interconnects with Cloud Eye, which provides a visualized platform for you to view monitoring metrics in a period of time and set threshold alarms.

Requires you to compile monitoring and alarm scripts, save monitoring data, and draw charts on your own.

Hosting

No need to pay for hosting fees.

Requires purchase of three servers and payment of high hosting fees.

Maintenance cost

Requires no extra O&M cost and supports second-level performance monitoring and threshold alarm and event alarm setting.

Requires large manpower investment and professional database administrator (DBA) for maintenance.

Deployment and scaling

Supports quick deployment, flexible application, elastic scaling, and one-click specification change.

Requires procurement, deployment, and coordination of hardware that matches original devices.

Log transfer

Stores slow query logs and error logs for one month.

Requires you to transfer, export, and query log information on your own.

High availability

Provides high availability capabilities, supporting second-level switchover and failover.

Requires self-setup of HA monitoring. Data may be lost after a manual primary/secondary switchover is performed using commands.

Data management

DAS is used to manage data. It provides a graphical user interface (GUI) and allows you to perform visualized operations on the console.

Requires self-installation of the graphical client, which may incur fees.
