What Are the Differences Between RDS and Other Database Solutions?¶
Function | RDS | Self-Built Database Service |
|---|---|---|
Service availability | For details, see Elastic Cloud Service User Guide. | Requires self-guarantee, primary/standby relationship setup, and RAID setup. |
Data reliability | For details, see Elastic Volume Service User Guide. | Requires self-guarantee, primary/standby relationship setup, and RAID setup. |
System security | Defends against Anti-DDoS attacks and promptly repairs database security vulnerabilities. | Requires procurement of expensive devices and software, as well as manual detection and repair of security vulnerabilities. |
Database backup | Automated backup | You need to find backup storage space by yourself and periodically check whether backup data can be restored. |
Hardware and software investment | Supports on-demand pricing without hardware and software investment. | Requires large investment in database servers. |
System hosting | Not required. | The hosting cost is high. |
Maintenance cost | Not required. | Full-time Database Administrators (DBAs) are required for maintenance, leading to high manpower costs. |
Deployment and scaling | Supports elastic scaling, fast deployment, and on-demand enabling. | Requires procurement, deployment, and coordination of hardware. |
Resource utilization | Bills users based on the resources actually used, resulting in high resource utilization. | Peak resource utilization is considered, leading to low resource usage. |
