MySQL is the most popular open-source relational database in the world, and Cloud Database MySQL(TencentDB for MySQL) enables you to deploy and use MySQL database in the cloud with ease. With TencentDB for MySQL, it only takes minutes to deploy a scalable MySQL database instance. Besides high cost efficiency, you can enjoy flexibly scalable hardware specs without business interruption. MySQL offers a complete set of database OPS solutions including backup rollback, monitoring, fast scaling and data transfer, simplifying your IT OPS and enabling you to focus on business development.


Easy-to-use Hosted Deployment

With a few clicks in the Tencent MySQL console, you can launch and connect to a production-ready MySQL database within a few minutes. MySQL is pre-configured with various parameters and settings for your selected server types. With the database parameter group, you can control and finetune the MySQL database.

Dedicated Kernel Optimization

MySQL instances provide industry-leading IO throughput capability with highly customized MySQL kernels that outperform self-built open-source MySQL-based databases. The performance advantages of MySQL allow you to use fewer databases to support more concurrent requests and simplify backend architecture, streamlining the overall IT architecture for easier management and OPS.

Completed Guarantee Mechanism

Tencent Cloud provides 99.9996% data reliability and 99.95% service availability with completed automatic data backup and lossless recovery mechanism. With the high reliability of MySQL, you can rest assured to put your data in the cloud with no worry about data loss. Meanwhile, the extra work and additional IT investment required by traditional OPS activities to ensure high data reliability can be eliminated.

Strong Sync Replication

MySQL kernel in many aspects, improving the performance of strong sync data replication. Meanwhile, it improves the phantom reading phenomena caused by the master/slave switching and the critical transactions caused by the recovery of CVM failure, improving data consistency in MySQL v5.6.

Comprehensive Daily Monitoring

You can view over 70 indicators in the MySQL console, including connection access, database load, query cache and storage engine, to comprehensively monitor your database health. You can also create custom monitoring views to compare the running instance loads in multiple dimensions for multiple instances over the same period or for different periods on the same instances. Abnormal databases can be detected fast in this way.

Custom Alarms

Custom alarms for resource thresholds can help you detect issues in MySQL operation which will be reported to and solved by the Tencent OPS team promptly.

Full-Process OPS Services

You don't need to care about the installation, deployment, update and troubleshooting of MySQL. Tencent MySQL team will have free you from worries. Switching between master and slave, troubleshooting and data migration are fully transparent to you. IP addresses and ports remain unchanged. IP drift is no longer a consideration for your applications. All those advantages help minimize your OPS costs.

Data Migration

With Data Transfer Service (DTS), automatic database migration can be achieved easily from self-built MySQL databases on CVMs to MySQL database instances as well as from MySQL databases in IDCs with public IPs/in other vendors' cloud to MySQL database instances, simplifying your database cloudization without manual migration and enabling seamless business transition to the cloud.

Data Disaster Recovery

Real-time data synchronization can be performed between the MySQL database in the local IDC and the Cloud Database through the data migration service. In case of database service interruption caused by power or network failure in the local IDC, backup MySQL instances can be rapidly switched to for disaster recovery; meanwhile, MySQL supports multi-availability zone in one city/cross-city disaster recovery to ensure high availability.
