Product Advantages
High Availability
By default, high availability is configured to mitigate the impact of failures, such as downtime, on cloud memory services. When the primary node fails, the secondary node is quickly promoted to become the new primary node to ensure continuous service.
The primary and secondary Redis architecture provides high availability across availability zones. Users can enable the "high availability across availability zones" feature based on their business needs, thereby enhancing service availability and achieving cross-machine room disaster recovery. However, because Redis employs asynchronous replication technology, the secondary node may experience slight lag behind the primary node during periods of high business pressure. Consequently, switching between the primary and secondary nodes may result in a small amount of data inconsistency.
Rich Architecture
Redis offers both primary-secondary and distributed architectures.
Primary-Secondary Architecture: In this setup, the replica nodes synchronously replicate data from the primary (master) node in real time during system operation. If the primary node fails, the system automatically switches to the replica node within seconds to continue business operations. This process is entirely automatic and does not impact the business, ensuring high availability of service.
Distributed Architecture: The distributed instance utilizes a distributed cluster architecture, where each node incorporates a high-availability primary-secondary setup that can automatically switch in the event of a disaster and migrate during a fault. Different capacity configurations of the distributed version can accommodate varying business demands, allowing the performance of distributed Redis to be scaled up as needed.
Complete Monitoring
We offer a variety of monitoring types for users, including usage, number of connections, QPS, Key number and so on.
Online Expansion and Contraction
Users can directly visually expand Redis on the console. The entire process is transparent to users and effectively meets the needs of business growth. Redis in primary-secondary mode supports expansion and contraction. Different capacity configurations of the distributed version can be applied to different business pressures, and distributed Redis can be expanded as needed.
Low Operation and Maintenance Cost
Effectively reduces the operation and maintenance cost. Users can create and upgrade instances according to their business needs, without having to purchase high-cost hardware in the initial stage of the business, effectively reducing initial capital investment and waste from idle resources; convenient and fast deployment management can reduce operation and maintenance costs.
Data Security
Data is stored persistently using a hybrid storage method that combines memory and hard disk. This approach provides high-speed data read and write capabilities while meeting data persistence requirements.
Backup and Recovery: The system performs automatic data backups every day and supports manual backups, ensuring robust data disaster recovery capabilities. It retains three copies of backups for free and facilitates one-click recovery from backups as well as backup downloads, effectively preventing data misoperations and minimizing potential business losses.
Network Isolation and Security Protection: In master-replica mode, users can set a password for access authentication, ensuring that access is secure and reliable.
