Various Architectures: Single Shard, Master-Replica, Read/Write Splitting, and Distributed Cluster
Single node instances are suitable for caching scenarios. Master-replica instances feature automatic failover. Read/write splitting instances apply to scenarios where more reads are processed than writes. Cluster instances can be scaled out.
The replica node synchronizes to the master node in real-time. If the master node fails, the system automatically performs a failover and restores the services within a few seconds. Then, the replica node takes over the workloads. Your service is not interrupted during the failover process. The master-replica architecture ensures the high availability of your services.
Cluster instances run in a distributed architecture. Each shard contains a master node and a replica node to ensure high availability. Failovers are triggered when the master node fails. Multiple specifications are provided to deal with different workloads. You can upgrade your instances to improve the performance of the database service.
Read/Write Splitting Architecture
The read/write splitting architecture applies to scenarios where more reads are processed than writes. Each read/write splitting instance supports a maximum of 100,000 writes per second and 600,000 reads per second. This helps you eliminate the performance bottleneck of reading and writing hotkeys.
Data Security: Backup and Restoration, Multi-Layer Network Protection, and Disaster Recovery
Supports automatic backup, quick restoration, multi-layer network protection, zone-disaster recovery, and geo-disaster recovery
Backup and Restoration
Automatically performs backups and supports disaster recovery. You can restore data that is accidentally deleted to minimize your business losses.
Multi-Layer Network Protection
Virtual Private Cloud (VPC) isolates data transmission at the transport layer. Anti-DDoS detects and mitigates volumetric DDoS attacks in real-time. It allows you to configure more than 1,000 IP address whitelists to block malicious IP addresses.
Supports zone-disaster recovery, geo-disaster recovery, and cross-region disaster recovery to avoid data corruption at the physical layer.
In-Depth Kernel Optimization
Alibaba Cloud Technical Experts have optimized the kernel of open-source Redis to prevent out-of-memory errors and patch vulnerabilities.
Elasticity: Multidimensional Scaling and Transparent Upgrades
Dynamic upgrades to improve the performance and capacity of your instances. You can also switch between different architectures without service interruption.
Data Capacity Expansion
ApsaraDB for Redis instances are available in different memory capacities. You can adjust the memory capacity of your instance to meet business requirements.
The cluster architecture allows you to scale the storage and throughput of the databases. This eliminates the performance bottleneck and can handle tens of millions of reads and writes per second.

You can perform common and high-risk operations with only a few clicks in the ApsaraDB for Redis console. For example, you can clone instances, back up data, or restore data.
Visualized Data Management Platform
The DMS console allows you to manage data in a visualized manner. This improves development and maintenance efficiency.
Kernel Version Management
The kernel version is automatically upgraded and defects are patched at the earliest opportunity. This facilitates version control. Configuration parameters are optimized to increase the system resource utilization.
Single node instances are suitable for websites that deal with heavy reads and writes but require cost-effectiveness. Single node instances are intended for caching services. They provide high QPS performance and use RDS to persist data.
High Read/Write Performance
The single threading feature allows Redis to handle up to 100,000 QPS and can withstand more traffic loads if it is upgraded to a single node cluster instance.
Protects your workloads from single points of failure.
Single node instances are cost-effective and applicable to caching services.
Game companies release new games to attract more players and increase market share. ApsaraDB for Redis can reduce the complexity of application development and dynamically scale out to withstand heavy loads.
In the gaming industry, elastic scaling is required when developers create duplicate servers and users transfer data to different servers. Data persistence can decrease the load on the database engine and reduce development complexity.
You can clone instances from backup files to meet the gaming industry requirements of creating duplicate servers multiple times a day.
Backup files are retained free of charge for seven days. You can restore data with a few clicks to ensure data security.
