Strengths of Single-Node Instances
High cost effectiveness
Computing resources start at as low as 3.685 USD/month, greatly reducing the deployment costs.
Large disks
Up to 30 TB storage space is available, with no limits on disk specification.
High security
Anti-DDoS protection
When your business suffers a DDoS attack, this feature can help you resist various attack traffic to ensure normal operation.
Protection against database attacks
Effectively defense against such database attacks as SQL injection and brute force attacks.
High reliability
The system adopts a distributed three-copy storage mechanism and guarantees that data is written in all three copies before returning a response of successful write. If any copy fails, the backend data replication mechanism can quickly create a new copy by using methods such as data migration, ensuring the availability of three data copies at all times and increasing the data reliability.
Strengths 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
You can monitor resources from multiple dimensions and customize alarming thresholds for them. You can also download reports about slow query analysis and SQL running.
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.
Strengths of Two-Node/Three-Node Instances
Flexible billing modes
Pay-as-you-go and monthly subscription billing modes are available, so you don't have to invest a lump sum of money in infrastructure construction.
Read/Write separation
Read-only instances can be mounted to TencentDB for MySQL. The one-source-multiple-replica architecture allows you to respond to massive requests. RO group with the load balancing feature is supported to greatly optimize the pressure distribution among read-only instances.
Powerful hardware for high performance
NVMe SSD features high IO performance, ensuring smooth reads and writes.
A single instance can sustain up to 240,000 QPS and 6 TB storage space.
High security
Anti-DDoS protection
When your business suffers a DDoS attack, this feature can help you resist various attack traffic to ensure normal operation.
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 to ensure security. Moreover, it can be backed up and stored for an extended period of time, allowing for data recovery in the event 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 7–1830 days based on data backup and log backup (binlog). Such backups can be retained for 7–1830 days.
Automatic disaster recovery
Automatic failure detection and failover are supported. Users are not aware of source-replica switchover or failover.
