    The strengths described in this document are exclusive to dual-node and three-node TencentDB for MySQL instances.

    Cost Effectiveness and Ease of Use

    • Read/write separation is supported
      Read-only replicas can be mounted to TencentDB for MySQL. One-source-multiple-replica architecture allows you to respond to massive requests. RO group with load balancing feature is supported to greatly optimize the pressure distribution among read-only replicas.

    • Powerful hardware ensures high performance
      NVMe SSD features high IO performance, ensuring smooth reads and writes.
      A maximum of 240,000 QPS and a maximum storage space of 6 TB are supported for an instance.

    High Security

    • Anti-DDoS protection
      When you suffer a DDoS attack, this feature can help you resist various attack traffic, ensuring the normal operation of businesses.

    • Protection against database attacks
      Effectively defense against such database attacks as SQL injection and brute force attacks.

    High Reliability

    Data is stored online in a source/replica architecture, ensuring high data security. Moreover, backup data can be stored for an extended time period, allowing for data recovery in case of a database disaster.

    • Data encryption
      Transparent data encryption (TDE) feature guarantees the security of real-time data and backup data.

    • Database audit
      Financial-grade data audit feature helps prevent core data theft, trace non-compliant operations, and locate malicious pulls.

    High Availability

    • Real-time hot backup
      The dual-server hot backup mechanism supports lossless restoration of data from the last 7–732 days based on data backup and log backup (binlog). Such backups can be retained for 7–732 days.

    • Automatic disaster recovery
      Automatic failure detection and automatic failover are supported. Procedures of source/replica switchover and failover are imperceptible to users.

    Advantages over Self-built Databases

    • Easy management of massive databases
      Databases can be managed via command line or console. Batch database management, permission setting, and SQL import are supported.

    • Data import and backup rollback
      Multiple data import methods are provided for initialization. Data is backed up automatically on a daily basis. TencentDB allows data to be rolled back to any point in time within the retention period based on backup files.

    • Professional monitoring and alarm
      Multidimensional monitoring and alarming based on custom resource thresholds are supported. You can also download slow query analysis reports and complete SQL running reports.

    • A variety of access methods
      Access to the public network and VPC is supported. You can connect TencentDB instances to your IDC, a private cloud, or other computing resources for deployment in a hybrid cloud conveniently.
