Cloud Database MongoDB

Cloud database MongoDB supports ReplicaSet and Sharding deployment architectures and comes with multiple enterprise capabilities including security auditing and time point backup.

Core Features and Services

Flexible Architecture

Services are provided by a primary node and three physically separated secondary nodes. When the primary node fails, the system will automatically select a new primary node from the three secondary nodes. When secondary nodes are unavailable, hidden nodes will take over to ensure service availability.

Cluster Architecture

Sharding service (Shard) and configuration service (configserver) are adopted with a three-node backup cluster architecture, making the cloud database more stable and reliable. The Architecture supports proxy service (mongos) and shard service (mongos)  for flexible configuration, as well as linear expansion of the cloud database's storage and performance.

Virtual Private Cloud

Services are deployed on Virtual Private Cloud built on the physical network using OverLay technology and are protected on the TCP layer with network isolation.

Data Security

The cloud database supports automatic data backup and one-click data recovery. Backup copies are stored in ChinaCache Object Storage and protected by multi-layer network protection mechanism to resist against 90% malicious data damages.

Flexible Expansion

A single shard can support a maximum of 25600 IOPS, store a maximum of 2T data, and bear a maximum of nearly 100,000 QPS application pressure. The Sharding mode can also support unlimited horizontal expansion.

DDoS Attack Protection

A monitoring system is embedded in the management console to keep customers updated on real-time database status, set up monitoring strategy and text message alert.

IP Whitelist Configuration

A monitoring system is embedded in the management console to keep customers updated on real-time database status, set up monitoring strategy and text message alert.

Backup and Recovery Mechanism

A monitoring system is embedded in the management console to keep customers updated on real-time database status, set up monitoring strategy and text message alert.

Easy Management

A monitoring system is embedded in the management console to keep customers updated on real-time database status, set up monitoring strategy and text message alert.

Solution Advantages

optimization

Special Performance Optimization

Cloud database MongoDB is equipped with ultra-large memory, brand new PCI-E SSD storage medium and next generation storage engine with an optimized native Mongo kernel. It can support 30K+ QPS.

monitor 2

Integrated Monitoring

Monitor disk usage, CPU load and QPS on single instances, primary nodes and secondary nodes. Customized alerts can be set up to notify abnormal behaviors in real-time.

isolation

Sharding Function

Support distributed cluster architecture with data stored on multiple physical servers through shard keys, and there is no upper limit for data storage.

flexible

Flexible Capacity Expansion

In a cluster architecture, when the database has a capacity bottleneck, it can be expanded horizontally by adding agent services and sharding services, and theoretically there is no upper limit for the expansion.

thumb up

Reliable Storage

Based on a distributed system and SSD high-performance storage, the database has a reliable system, hardware, and architecture. Three backup copies are saved on separate nodes, ensuring data availability at all time.
