The three-node replica set high-availability architecture delivers extremely high business availability.
ApsaraDB for MongoDB uses a three-node replica set high-availability architecture. The three data nodes are located on different physical servers and synchronize data automatically. The primary and secondary nodes both provide service. When the primary node fails, the system automatically elects a new primary node. When the secondary node is unavailable, the standby node takes over services.
Automatic backup and one-click recovery can resolve over 99.99% of system failures.
Data is automatically backed up and uploaded to the Object Storage Service (OSS) every day, improving data disaster recovery capabilities while effectively reducing the consumption of disk space. The backup files can restore the instance data to the original instance. This prevents irreversible effects on business data caused by incorrect operations or other actions.
The multi-level security defense system can protect your network against over 90% of attacks.
Anti-DDoS protection: Provides real-time monitoring at the network entry point. When high-traffic attacks are identified, their source IP addresses will be cleaned. If cleaning is ineffective, the black hole mechanism is triggered.
IP white list configuration: Supports the configuration of up to 1,000 server IP addresses, which are allowed to connect to MongoDB instances, directly controlling risks at the source.
Ease of use
Sound performance monitoring will manage more than 60% of your O&M workload.
ApsaraDB for MongoDB monitors instance information in real time, such as CPU utilization, IOPS, connections, and disk space, and reports alarms. This helps keep you updated on instance statuses at all times.
Replica sets can be elastically resized.
ApsaraDB for MongoDB supports three-node replica sets to allow for elastic resizing. You can change the configuration of your instance if the current configuration is too high or cannot meet the performance requirements of your application. The configuration change process is completely transparent and will not affect your business.
Cluster mode helps cope with business peaks.
ApsaraDB for MongoDB supports cluster versions. Users can independently select multiple mongos and multiple shard nodes. As your business develops, you can change the configuration for your mongos and shard nodes if their configuration is too high, or cannot meet the performance requirements of your applications. The configuration change process is completely transparent and will not affect your business.
At the same time, you can add or delete mongos and shard nodes as needed, to meet the changing needs of your business.
