Product Advantages

  • High AvailabilityHigh Availability

    High availability is enabled by default to prevent downtime and other failures from affecting the cloud memory service. When the primary node fails, a replica node is quickly promoted to the new primary to continue serving traffic. The primary-secondary Redis supports cross-AZ high availability, allowing users to enable this feature based on business needs for improved availability and cross-datacenter disaster recovery.

  • Data SecurityData Security

    Uses a hybrid memory and disk storage approach to deliver high-speed read/write performance while meeting data persistence needs. Supports manual and automatic backup with free backup storage and strong data disaster recovery capabilities. Supports restore from backup and download to prevent accidental data operations and minimize potential business losses. Private network isolation provides security protection, and the primary-secondary version supports password-based access authentication for secure and reliable access.

  • Rich Architecture OptionsRich Architecture Options

    Redis offers two architecture options: primary-secondary and distributed. Primary-secondary architecture: the replica node syncs data from the master node in real time. When the master fails, the system automatically switches within seconds — the replica takes over with no impact on business and full service availability guaranteed. Distributed architecture: uses a distributed cluster where each node adopts a high-availability primary-secondary setup, enabling automatic failover and fault migration.

  • Online ScalingOnline Scaling

    Users can visually scale Redis directly from the console with the entire process transparent to the user, effectively meeting growing business demands. The primary-secondary version supports both scale-up and scale-down. The distributed version offers different capacity configurations for varying workloads, with on-demand performance scaling.

  • Comprehensive MonitoringComprehensive Monitoring

    Provides multiple types of monitoring metrics including memory usage, connection count, QPS, and key count. Supports automatic alerting on monitored items, with alert templates and custom alert configurations, delivered via SMS, email, and other channels.

  • Low O&M CostLow O&M Cost

    Effectively reduces O&M costs. Users create or upgrade instances based on business needs without costly upfront hardware purchases, minimizing initial investment and idle resource waste. Fast Redis deployment and streamlined instance management further reduce deployment and maintenance overhead.
