Internet

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

Horizontal Sharding

Exponentially improve the processing capabilities of your applications.

Scalable Storage

Rebalance data across all databases after you add RDS DB instances in just a few clicks.

High Read/Write 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.

IoT

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

Highly Concurrent Writing

Allow a great volume of data to be stored and written to your database in real time.

Quick Query

Shard data according to reasonable sharding rules, multiplying the query speed.

Low Costs

Enjoy all the performance of high-end databases if you deploy instance clusters on general computing ECSs.

Traditional Industry

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

High Reliability

You can recover from faults within seconds if you deploy a DDM instance cluster across AZs.

High Security

Secure your data with VPCs, subnets, security groups, SSL connections and audit logs.

Horizontal Sharding

Exponentially improve processing capabilities of your applications.
