Robust Performance
With DDM, your database can handle up to 9 times more connections than a single-node database can handle. Easily process millions of concurrent requests and retrieve a record from petabytes of data.With DDM, your database can handle up to 9 times more connections than a single-node database can handle.

Traditional Industry
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.
Advantages
Exponentially improve the processing capabilities of your applications.
Rebalance data across all databases after you add DB instances in just a few clicks.
With DDM, your database can handle up to 9 times more connections than a single-node database can handle. Easily process millions of concurrent requests and retrieve a record from petabytes of data.
IoT
Sensing and monitoring devices collect huge volumes of data and frequently issue commands. DDM is a great option for such devices because it supports highly concurrent access and massive data storage while also reducing costs.
Advantages
Allow a great volume of data to be stored and written to your database in real time.
Shard data according to reasonable sharding rules, multiplying the query speed.
Enable you to enjoy all the performance of high-end databases if you deploy instance clusters on general computing ECSs.
Traditional Industry
Governments, large enterprises, and banks have to purchase expensive midrange computers and high-end storage devices to store huge amounts of data and handle highly concurrent requests. DDM can inexpensively resolve all of these problems.
Advantages
You can recover from faults within seconds if you deploy a DDM instance cluster across AZs.
Secure your data with VPCs, subnets, security groups, SSL connections and audit logs.
Exponentially improve processing capabilities of your applications.
