Provides multiple layers of security protection (including VPC, subnet, security group, DDoS protection) and SSL secure access for complete protection against network attacks.
Provides smooth scaling without interrupting your services or need to modify code. Distributed architecture scales up storage with easy addition of more nodes to meet your in-the-moment requirements.
Provides two HA architectures: replica set and cluster. Automatically creates multiple copies of your data for fast and assured recovery. Restores data with just a few clicks to avoid data loss caused by operator error.
Allows you to restart, back up, and restore DB instances with just a few clicks on the DDS management console and monitor CPU utilization and IOPS in real time.
With DDS, you can store game data for millions of players and use distributed DDS clusters to cope with high loads during peak gaming hours.
Embedded documents eliminate the need to use SQL JOIN statements, reducing database processing loads and application development complexity. Flexible schemas also facilitate rapid development and iteration.
Sharded clusters provide enough capacity to store data into the TB range.
Mobile apps, including those for shared ride services, live TV, and social media platforms, need to collect user location information and store, query, and analyze various types of complex data. DDS is compatible with MongoDB, which supports unstructured data models and provides powerful query capabilities.
DDS can store geographical location data.
DDS provides 2D geospatial indexes to calculate geographical locations, text indexes to support text search, and TTL settings to limit the lifespan of documents.
Intelligent IoT terminals need to collect various types of data, store device logs, and analyze information in multiple dimensions. In recent years, IoT services have grown rapidly, with huge volumes of data and increasing access traffic that require horizontal expansion capabilities for data storage.
DDS sharded cluster provides high write performance to meet the requirements of terabyte-scale databases.
DDS supports applications with high QPS rates, and its sharding architecture can be scaled in or out to flexibly cope with application changes.
Many organizations need to process and store data into the TB range, requiring data to be written to databases in real time and dynamic analysis capabilities in big data computing.
With a complete data analysis utility, you can query statements or scripts, and distribute requests to DDS.
DDS DB instances can be scaled up to support growing services and data volumes in content management systems.
Stores unstructured and complex types of data and provides powerful query capabilities.
Provides cost-effective single nodes. Three-node replica sets ensure high availability. Distributed clusters support horizontal scaling.
DDS is compatible with MongoDB and supports JSON/BSON data, regular query, array query, and embedded document query.
The single node architecture is suitable for storing non-core data, and is often the preferred choice for environment testing, learning and training, and certain non-critical internal enterprise systems.
A DDS sharded cluster consists of mongos, config, and shard. Data read and write requests are forwarded by mongos, while mongos reads configuration settings from config and allocates the read and write requests to shards. This design helps you efficiently cope with scenarios that require high concurrency.
A replica set consists of three nodes: primary, secondary, and hidden. If the primary node is faulty, the secondary node assumes its role. If the secondary node becomes unavailable, a hidden node will take over services to ensure high availability.
Provides a visualized database management and monitoring platform.
Provides multi-layer protection for data security and works with OBS to restore data quickly.
DDS provides DB instance creation, backup, and restoration functions, and log and parameter management.
DDS provides real-time monitoring information about CPU utilization, IOPS, the number of active connections, and disk usage, and allows you to customize alarm rules.
VPCs allow you to create private, isolated virtual networks.
Security groups define IP address and port rules, enhancing the security of access between DDS and other services.
SSL encryption enables higher levels of security over in-transit data.
Backup and Restore
The automated backup policy is enabled by default. Data is automatically backed up every day and stored in OBS. You can restore backups to a new instance quickly.
