Benefits
-
Custom Sharding
Choose from range or hash sharding, or a wide range of other sharding algorithms.

-
High Scalability
With DDM, you can scale your compute and storage resources separately to avoid horizontal scaling bottlenecks of single-node databases.

-
Read/Write Splitting
DDM leverages read replicas of data nodes (RDS for MySQL instances) to reduce latency to less than a second, with no need to reconstruct workloads.

-
Visual O&M
DBAs can manage schemas online and customize DB engine parameters based on monitoring data and logs.

Why DDM?
Different from traditional single-node databases, DDM can store massive volumes of data, handle concurrent requests, and speed up access to large tables and complex computing.
Reliable and Scalable Distributed Relational Database Service
- Highly Reliable
DDM distributes data across multiple data nodes, each of which can offload data storage and computing pressure from a DDM instance even if your service volumes are blowing up. If a fault occurs, impacts on your services are greatly reduced.
- Linearly Scalable
DDM lets you scale compute and storage separately. You can add nodes to a DDM instance or scale up its node class without interrupting services. Alternatively, add shards or data nodes to distribute data from one large table to multiple tables as services grow.
Multiple Security Policies for Security and Privacy
- Unified Authentication
DDM works with IAM to control access to cloud services and resources and provide fine-grained authorization on the management plane.
- Access Security
DDM allows you to set inbound and outbound rules for security groups to control network access to your databases.
- Audit
DDM works with CTS to record key operations on your resources.
Simple Operations, Low Costs, and Sustainable O&M
- Easy to Use
DDM is compatible with MySQL licenses, syntax, and official MySQL drivers.
You can import data into DDM and migrate your databases to the cloud.
Read and write requests can be split without the need to modify service code.
- Easy to Deploy
DDM instances are easy to deploy online. This shortens project cycles as you migrate your services to the cloud. You do not need to purchase, deploy, or configure a DDM instance like you do for a self-built database.
- Cost-Effective and Comprehensive O&M
DDM provides stable performance, comprehensive O&M, and excellent technical support. With these advantages, it is actually more cost-effective than open-source products. Different node classes are available, so there is always a choice well suited to your specific needs.
Application Scenarios
Internet
Market-driven applications in e-Commerce, finance, gaming, and social networking need a database that can handle sudden traffic surges and increased loads caused by dramatic growth in demand of data. DDM is a perfect fit for such highly demanding applications as it greatly improves database processing and speeds up your system.
