2. Hardware and Software Deployment Costs Comparison
Comparison Item | TDSQL-C for MySQL | Database Built with CVM | Database Built with Self-purchased Server |
Hardware and spare parts costs | The cost of a TDSQL-C for MySQL instance. For example, the cost of an instance with 4 CPUs, 8 GB memory, and 100 GB storage space is about 1392 USD per year. | At least two CVM instances are required as primary and replica instances. The cost of two CVM instances, each with 4 CPUs, 8 GB memory, and 100 GB storage space (with an IOPS capability of 4,800), is about 1392 USD per year. | At least two database servers are required. The cost of each server, with an IOPS capability of 8,000, is about 1114 USD. One private network switch is used for connecting to the front-end web server (a cheap 1U unmanaged switch costs about 139 USD). Subsequent hardware damage and replacement will incur at least an additional 30% in costs. Hardware cost: (1114 × 2 + 139) × 130% = 3077 USD. Annual cost: 3077 USD/3 = 1025 USD (hardware is depreciated over 3 years). |
Server room hosting costs | Covered by service provider, no charge. | Covered by service provider, no charge. | The hosting cost for 1U cabinet space is 417 USD/year. There are two 1U servers and one 1U private network switch that need to be billed. Server room hosting cost: 417 × 3 = 1025 USD. |
Bandwidth costs | Covered by service provider, no charge. | Within the same region, CVM instances can communicate through the private network without incurring charges.
If in different regions, CVM instances can communicate through the public network, and public network traffic fees will be charged. | For private network use only. There are no public network charges. |
Database O&M engineer costs | Managed O&M, quickly resolving various failures. AI tools assist in resolving optimization issues.
Database maintenance is covered by the service provider, with no personnel costs. | For a junior DBA engineer, assuming the current project occupies 30% of the engineer's workload, the personnel cost for one year would be around 2785 USD. | For a junior DBA engineer, assuming the current project occupies 30% of the engineer's workload, the personnel cost for one year would be around 2785 USD. |
3. Peripheral Ecosystem Service Costs Comparison
Comparison Item | TDSQL-C for MySQL | Database Built with CVM | Database Built with Self-purchased Server |
Database monitoring system | Second-level monitoring data for 79+ metrics is provided for free. | At least one CVM instance is required for monitoring, collection, storage, and display. The cost of one CVM instance with 4 CPUs, 8 GB memory, and 300 GB storage space (approximate storage capacity for one year's monitoring metrics) is about 975 USD per year. | At least one database server is required. The cost of the server is about 1114 USD. Subsequent hardware damage and replacement will incur at least an additional 30% in costs. Hardware cost: (1114 × 1) × 130% = 1448 USD. Annual cost: 1448 USD/3 = 482 USD (hardware is depreciated over 3 years). |
Database O&M system | Covered by service provider, no charge. | The annual cost of a professional database O&M system is about 5571 USD. | The annual cost of a professional database O&M system is about 5571 USD. |
Database backup system | Currently free | At least one CVM instance is required for backup system storage. The cost of one CVM instance with 4 CPUs, 8 GB memory, and 200 GB storage space (can only retain 200 GB of backup data) is about 835 USD per year, and you need to build the backup and recovery capabilities on your own. | At least one database server is required. The cost of the server is about 1114 USD. One private network switch is used for connecting to the backup server (a cheap 1U unmanaged switch costs about 139 USD). Subsequent hardware damage and replacement will incur at least an additional 30% in costs. Hardware cost: (1114 × 1 + 139) × 130% = 1628 USD. Annual cost: 1628 USD/3 = 542 USD (hardware is depreciated over 3 years). |
